Defect SummaryToyota is recalling certain model year 2004-2009 prius vehicles manufactured august 6, 2003, through march 30, 2009 and fchv-adv vehicles manufactured december 12, 2008, through september 13, 2011. during manufacturing, a scratch may have occurred inside of the electrically driven water pump at the coil wire. the coil wire may corrode at the scratched portion.
Consequence SummaryThe corroded coil wire may break and the water pump could stop. the corroded coil wire could cause a short circuit between coil wires and a possible open fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. this may increase the risk of a vehicle crash.
Corrective SummaryToyota will notify its owners, and dealers will replace the electric water pump, free of charge. the recall began on january 17, 2013. owners may contact their toyota dealer or the toyota customer experience center at 1-800-331-4331.
NotesOwners may also contact the national highway traffic safety administration vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to www.safercar.gov.

 Odi opened pe05-029 based on 33 reports of alleged gasoline engine stalling on the subject vehicles.the subject vehicles are gasoline/ electric hybrid vehicles that can be operated in gasoline or electric modes, or a combination of both depending on the power demand.all reports allege that the gasoline engine shut down suddenly without warning.some of the complainants reported that the vehicle continued to operate using the electric mode for a period of time after the gas engine stalled and some reported that the vehicle shut down at the same time that they felt the gas engine stalled.some consumers reported that they were able to restart the vehicle either immediately or after allowing the vehicle sit for a short time, whereas others reported that they had their vehicle towed.during pe05-029, additional failure data was identified as noted in the failure report summary above.the complaint data represents incidents where engine stalling was alleged or where the vehicle was alleged to have one of the various conditions that causes the gas engine to stall.in its august 26, 2005 response to odi's information request, toyota identified various conditions that could cause the subject vehicles to experience a gas engine stall.if this happens, the driver is alerted by an audible sound and various warning lights.the vehicle will continue to operate in the electric mode and the electrically-powered brake and steering operation will continue to function normally. analysis of the warranty data indicated that over 97% of vehicles experiencing a gas engine stall resulted from an issue with the program logic in the electronic control module (ecm) system, which may cause the ecm system to not start the gas engine when required.as a result, the vehicle will enter the limited operation mode described above.the majority of the odi complaints also indicated that the driver experienced this condition in conjunction with the engine stall. during october 2005, toyota informed odi that it would initiate a special service campaign (ssc) to reprogram the ecm software on approximately 75,000 my 2004 and early 2005 subject vehicles to address the gas engine stalling condition.during this ssc, dealers will also apply special dielectric grease to a transaxle connector to prevent water intrusion which may also cause similar limited operation conditions.based on odi's analysis, this remedy should address most of the incidents resulting in a limited operation mode.given these circumstances, further use of the agency resources in this matter does not appear to be warranted.accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by nhtsa that a safety-related defect does not exist.the agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.

 We were driving on the highway at night and suddenly, without warning, the engine stalled completely, the car died, and all of the warning lights came on, including a red triangle, check engine, brake, and some others. the prius lost power and i had to turn on the hazard lights and coast to the shoulder. we called the aaa towing service and 911 (as the shoulder was very narrow and we could not get out of the car). the officer and the tow truck driver checked for all possible driver errors, including gas, but did not find anything out of the ordinary (the gas gauge showed 5/8 full). the car was towed to the toyota dealership in sunnyvale who are working to determine the cause. this was a very dangerous situation as we were driving on a highway, with a child in the car, at highway speeds at night and the car suddenly died. it has left us shaken and we will be contacting toyota to see if they have a fix for this.

 I was driving on the highway when my vehicle's check engine light came on. shortly after i saw a large amount of smoke coming from the engine. i pulled over and shut off the car. car smelled like burned plastic and smoke. i was worried that the car could catch on fire or blow up! i had the car towed to my nearest toyota dealership.toyota claimed that the three way coolant control valve had failed and the steam came from a ruptured line in the coolant system. the job cost me $422.32. i didn't mind paying the service but after careful research into the problem with the 3-way control valve on the prius i had learned that this is a wide spread problem.apparently the valve tends to stick causing no flow of the coolant fluid. i feel toyota should fix this problem before someone gets hurt either by getting burned from a ruptured line or the car catches on fire.

 I drive a 2005 toyota prius. my car has 26,000 miles on it; which is very low mileages. while i was on the highway, my car`s lights on the dashboard starts to flash. the brake system warning light and buzzer comes on along with the abs warning light and the malfunction indicator lamp. i had nowhere to pull aside. after two minutes the warning signs shut off so i kept driving. five minutes later, all the warning lights come on so i decide to get off the highway to take it to the knoxville toyota dealer. as i`m exiting the highway, i immediately realized that i had no breaks (when i pressed the brake pedal with my foot it automatically touched the ground)! i remembered that my dad always told me that in case of a brake emergency to pump the paddle until the breaks work. i almost crashed into another car; the exit ramp was very steep. i was going about 50 miles per hr by then; luckily i managed to stop while i kept pumping my breaks. i took it to the dealer right away. they checked my car and replaced: pump assy. water, super long life c, invertor coolant pump, sliding yoke, reflashed engine and hv ecu and shaft kit. steeri. i found my case very dangerous and my life was at risk. not only was my life at risk but as well as other individuals. i would hate for this to happen to someone else! it was scary and i felt like my life might have been over.

 I was involved in an accident with my 2005 prius on 3/29/2006. the cause of the accident remains a mystery. i was sitting at an intersection, waiting for traffic to clear. witnesses reported that i pulled out into the oncoming traffic, resulting in a collision with another vehicle. due to the injuries i suffered (a minor concussion resulting in retrograde amnesia), i had no recollection of the period prior to arriving at the intersection up until the paramedics removed me from the vehicle. as such, i can't explain exactly what happened. while i have no proof of this, it seems that a possibility would be an issue with the stuck accelerator that's being reported relating to the prius. i've been at a loss to explain why i would have pulled out in front of oncoming traffic at an intersection that i was very familiar with. when i heard of the acceleration issues with the prius, i wondered if that could have been the cause. since the vehicle was totaled, it's no longer available for inspection. i thought i'd submit this report to add to the suspected cases of accelerator issues. *tr

 2005 toyota prius stalled while driving and in motion. i own a 2005 toyota prius that i had just driven on highway about 25 miles and then was on local road. the vehicle stalled without any warning and all lights came on. the car was not responsive to gas and engine was shut. so i had to pull over. the car will not start and had to be towed to the dealer. fortunately, it was during off peak time and i was on local road. if it had been during peak time and on highway, the consequences would have been significantly different. the dealer had no technical details as to why this happened. he said it was software issue. *tr

 I have a 2005 toyota prius with 255k miles. i service my car regularly (about every 5 weeks). when i started my car after work, none of the dashboard lights came on. i put my car in drive and the car moved forward. i drove my car about 60 miles and stopped by the store. i became alarmed when the car wouldn't shut off. i pressed the power button several times but the car would not turn off. i drove the car to the stafford toyota at approximately 7:30pm and requested assistance from the sales manager (since the service department was closed). the sales manager confirmed that the car was not supposed to operate without the dashboard lights because there was no way to determine if the car was on and whether the car was in park, reverse or drive. after numerous attempts of holding down the power button, the car finally shut off. when i restarted it, the lights still did not work. *tr

 2005 toyota prius went into a sudden engine stalling mode. i do realize that toyota has a recall on such vehicles, but the toyota dealership that i took it to, the same place where i bought the vehicle, that had a prius expert has been diagnosing this problem for a day with no answers / anticipated fix date. this is annoying to say the least, as toyota does not seem to have taken the time to train it's dealerships on their own recall information. i could steer and operate the vehicle in electric only mode. pressing the power key would not power off the car. hence the battery started to drain. opening the passenger door and pressing the power key, seemed to have been able to stop the car, not sure whether this was timing, or some coincidence. starting the car again, made the gasoline engine come on for the purpose of replenishing the charge for the battery, with the dash still displaying the same issues. also, pressing the accelerator again, does not raise the rpm of the gasoline engine. its stalling continues after a power cycle. *ak

 I took my toyota prius in for the recall noted in pe05029 and since have lost 8 miles per gallon in performance. i contacted toyota customer service to let them know and asked if they could tell me if other customers were experiencing the same problem. the reply was that customer service information is proprietary and that they would record my complaint but could give me no further information. i am not sure the car would still meet the epa mileage rating originally given. *nm

 Possibly relevant to current prius software reliability investigation number : pe05029 i spoke to gilles labelle of westboro toyota in westborough massachusetts regarding the toyota prius (this was a pre-sales conversation; i do not at present own a prius though until this conversation i was very close buying one; now i find myself taking a step back to ensure i've done my own due diligence). he mentioned the use of a reset sequence to reboot the car in the event of problems as a way to avoid the need to have the car serviced; i asked him how often he had to reboot his own prius; he didn't answer directly but instead said that he had helped about 100 customers through the reboot process. i am a operating systems software engineer by profession and was alarmed at this just hit reset attitude towards systems failures; ideally crashes in the field should be rare enough that each one can be root-caused, rather than shrugged off. *jb

 I was driving my toyota prius on the freeway and the vehicle died at 55 mph. the engine light illuminated and there was no power to the accelerator. fortunately, traffic was light and i was able to coast to a secure spot on the side of the road. this happened on the approach to the bay bridge, which would have been a potential disaster had it died on the bridge itself. the car did not start again on my first attempt, but it did start 5 minutes later. i took the car to the toyota dealer and they said they installed new information into the computer. i want to know why, if they know it needs new information, did i not receive a letter asking me to come in for service? this could have been really disastrous, and i fear that it will be for someone else. *jb

 Dear nhsta, on may 20 of 2005 i was driving my 2005 toyota prius when all of a sudden the gas engine stopped working and 4 dash warning/faults lights came on (red triangle; check engine; brake fault; vehicle stability control fault). i continued driving for 3 miles on the electric motor until the battery charge light indicated near complete battery discharge. i turned off the car, waited 30 seconds and turned the car back on. immediately the gasoline engine started and the battery began to charge. at this point only the check engine and red triangle lights came on. i drove to the toyota dealer who said that my problem sounded like the stalling problems with the 33 reported cases of 2004/05 prius stalling. toyota upgraded the engine ecu and the car has been fine ever since. however, i wanted to let nhsta know so that they know that this prius stalling problem affects more than just 33 prius owners. also, i worry that toyota does not know for certain that the problem is fixed premanently. thanks, gary beaupre

 I was driving 20mph when a red alert light came on the screen on my prius; it said gps underneath it so i ignored it, thinking i would be ok since i did not need my gps system. i sped up to about 30mph and suddenly was not able to accelerate although i was pressing down on my accelerator. i came to a stop at the traffic light on a green; luckily there was no collision. the electric mode remained intact for the next 2.5hrs untli the car was towed so i could still turn the car on.

 With approximately 7100 miles on my car on friday march 25, 2005 i was driving on local roads between 20 to 40 miles per hour when the car began bucking very badly .. shortly thereafter the check engine light turned on. worried that the vehicle may completely stall and quit on the open road i returned home and called my local arlington toyota dealer. i brought the car in the following morning (saturday march 26,2005) to check out the problem.they had the car all day and still could not identify why the car was stalling. since i was schedule to be away the following week (trip to las vegas). i gave permission for techs to keep car all week if necessary. on monday of the following week, i recieved a call from tech at my hotel that they had fixed the problem. he claimed it was a misfire in #1 cyclinder. so they replaced spark plug #1. however, he also told me not get the car engine wet. he warned that if i ever returned the car with a wet engine again that my warranty would be voided. i told him that i never open the engine compartment and that i would never intentionally put water directly on the engine. particullary on such a sophisticated car such as a hybrid. in the past 10,000 miles that i have owned the vehicle i have taken it through the car wash a total of three times.i picked up the car upon my return from las vegas on friday april 1,2005. i am happy to report that the car has been running fine ever since. however, since the recent rash of news reports of complaints filed around the country of the prius stalling i am wondering if the tech at arlington toyota had misdiagnosed the problem i experience this past march.

 Reported incident to toyota customer support -- incident: 050412-000111 responses received from toyota was that the computer was fixed based on a technical service bulletin. no recurrence since the fix. to: toyota customer support sir or madam: i bought my 2005 prius new from mechanicsville toyota on december 1, 2004 and generally was quite satisfied with the car and the great gas mileage it provides. however, last thursday, 4/7/05, with 4738 miles on the odometer, while driving home from work, all the lights on the dash went on including the master warning light, check engine light, vsc light, and the multi information display is showing the red hybrid system warning light. the car lost power and i had to limp it home. the energy consumption display for the battery pack showed one red bar and the fuel gauge had two bars left. i called toyota roadside assistance which promptly dispatched a tow truck and delivered the car to the dealer. the dealer did a diagnostic test the following morning, friday, 4/8/05, and could not find anything wrong. the only explanation i got was that this is a known isssue with 2 bars of fuel left and the cause was that the engine sucked in air with stops or turns. is there a further explanation or fix for this problem? i feel that this is a safety issue. i cross railroad tracks to and from work daily and definitely will not want this car to stall on the tracks or anywhere on the road. my wife and i are a multiple toyota owners: 95 camry wagon and 93 previa. i used to own an 83 tercel and my wife and step daughter have and still own a 96 tercel. these cars have been extremely reliable so that my experience with the prius comes as a shock. i look forward to hearing from you on this safety issue. sincerely, apolinar ilog glen allen, va email: pilog@comcast.net

 The consumer had the vehicle for 2 weeks and had an episode where the engine stalled on the highway. the consumer believed it may have been caused by a momentary event to shift it incorrectly from the braking mode. when the consumer first attempted to put it in reverse, it wouldn't take then, and it would not take into the proper drive mode either. the engine had stalled, and would not go into drive. the consumer stopped the vehicle, and was able to restart it. the consumer had not experienced problems since then. the consumer called and reported the problem to toyota. *ak gasoline engine on hybrid vehicle failed to kick in or stalled. *sc *jb

 Gas motor stalled while driving on highway at 55 mph. electric motor continued to operate until the battery was depleted, about 1 or 2 miles. i was unable to pull the car over because i was in a construction zone. it was difficult to turn the car off, because of the lack of a key, but once i did restart it, it worked fine.

 I was traveling at about 70 mph on the interstate, when the engine stalled. i was close to an off-ramp and was able to coast off of the exit. at the bottom on the exit i was able to start up again by shifting into drive.

 I had been driving my 2005 toyota prius at 40mph when i accelerated to pass a car and then had to stop briefly at a traffic light. when i pulled away from the light i noticed that the car felt very sluggish and wouldn't accelerate over 40 mph. i then realized that i was driving on the hybrid system only and that the engine had stalled. a big red exclamation point lit up on the dash and i was able to coast into a parking place off the highway. when i attempted to restart the car it did nothing. i called toyota service and explained my problem and he arranged a tow truck pick up my car but told me that since it was 5pm they wouldn't be able to look at it until the morning. the next morning they told me that the car started without incident and although they ran extensive testing they could find nothing wrong. they wanted me to come and pick it up but i refused stating that there definetly was something wrong with this car and that i was just glad that it didn't happen earlier in the day when i was on i-95 going 80 mph with a semi in back of me. i also told them that i had done some research on my own at priusonline and yahoo prius forum and found that there were more people who had the same problem and in most cases it was found to be due to a few codes that needed to be updated in the cars computer. i then asked them to check these specific codes. when i called back the next day they said that they ran the codes and found nothing and had taken the car for a long drive but had no problems. they released it to me and it has driven just as perfectly for me as it did up until the 1 second before it's engine quit without warning. i know that something potentially dangerous happened to my car that day and that there is just as much chance that it will happen again since nothing was fixed. i hope that you can help to avoid something potentialy tragic happening to me or someone else.

 2005 toyota prius stalled on an overpass with no shoulders. the transmission became stuck in park, and the vehicle could not be pushed since the front wheels were locked up. the car was eventually towed, and it had to be dragged onto the flatbed wrecker since the front wheels would not roll. the problem was determined to be a failed pump for cooling the inverter. the pump failed such that it blew a fuse that also controlled the transmission shifter, preventing the car from being put into neutral so that it could be pushed out of traffic lanes. this is a very unsafe failure mode.

 2005 prius stalling problem!! i never received any notification on this issue. as the article saidtoyota motor sales (tms), u.s.a., inc., will launch a special service campaign involving certain 2004 and early 2005 model year prius sold in the u.s. on the involved vehicles, an issue with the program logic in the electronic control module (ecm) system may cause some or all of the following warning lights to illuminate: master, hybrid system, engine, vehicle stability control, and brake. if this occurs, the vehicle will enter a fail-safe mode which allows limited operation via the electric motor. however, the electrically-powered brake and steering operation will continue to function normally if this condition occurs. the electric motor will also provide enough power to allow the driver to pull the vehicle over and away from traffic. once the vehicle is stopped, the driver may be able to restart the gasoline engine in the vehicle by pushing the start button.toyota is proactively conducting a campaign in the interest of its customers. toyota will inform owners of the involved vehicles with a special service campaign notification letter sent via first class mail beginning in late-october. owners are requested to contact their local toyota dealer for diagnosis and repair upon receiving their notification. toyota will reprogram the ecm system at no charge to the owners of the vehicle. nhtsa action number : pe05029 nhtsa recall campaign number : n/a component : engine and engine cooling engine and engine cooling:engine unknown or other my car have this same issue while i was on a freeway. i called toyota dealership and was told that i would have to pays around $100 to get analysis. what can i do to get toyota to correct this when they never sent me a notice for this problem. i bought this car brand new from toyota around summer of 2005. best regards, james le

 I'm writing about an defective inverter cooling pump in my 2005 toyota prius. i was driving when all of a sudden my car loses the ability to accelerate. numerous warning lights came on as i coasted to a stop in a nearby neighborhood. the car would not shut off at first. after i finally got the car to turn off, it would not turn on again. the display in the center of the dashboard would come on fine, but when it came time for the main engine to turn on (when pushing the start button), it would blink and shut off immediately. when i took a look under the hood, i could smell something electrical burning. i finally got the car towed to a local shop that was toyota/lexus certified. they figured out that the inverter cooling pump was defective and it was blowing fuses (hence the smell of something electrical burning). total cost was almost $500 for the repair: parts and labor. i tried calling toyota to see if i could get any type of reimbursement, but i got many reasons why i should not get one: - the warranty was for 60,000 or 8 years. i was in the 8 years, the mileage was 62,000. (i guess customer service does not mean much - previously i own a 94 toyota corolla - 16 years with a toyota car) - i did not get it repaired at a toyota dealership (even though they were toyota certified) - i did not buy the car new. (so if you buy a used toyota, apparently that does not make the car a toyota anymore.) bottom line, after being fixed the car runs even better then before the inverter cooling pump failure: better gas mileage and no more phantom steering wheel movements when driving on the highway (happened when the engine would switch over to battery and vice versa).

 I am writing about an incident with my 2005 toyota prius. on july 20, 2009 as my wife was driving our prius the engine light went on. she immediately drove into the parking lot of a small business and stopped the car. we had it towed to a repair shop. the mechanics there diagnosed the problem. the inverter pump that supplies coolant to all the engine parts had malfunctioned. the mechanics told us that the toyota company was aware that this problem could occur on our 05 prius. if we had the car towed to a toyota dealer the defective inverter pump would be replaced with a more recent model free of charge. the next day we had the car towed to the dealership. they examined the car and verified that the problem was a defective inverter pump. their codes as printed on their invoice number 524093 [21 july 2009] are 34352 pulled code poa93, sub code 346-inverter cooling system performance. found tsb eg001-07 to correct this concern. replaced inverter water pump as per stb. this catastrophic malfunction occurred without any prior warning. we have maintained the car with regular maintenance as per the schedule in the owners manual. we were very lucky that the malfunction occurred while we were in town. since we live in new mexico the malfunction could have occurred out in one of our deserts or on one of our mountains. we are both 73 years of age and both cancer survivors. the last thing that we needed was to be stranded somewhere or to have the engine completely destroyed if we were not able to immediately stop the car. i do hope that toyota will be required to perform a recall on the prius models that have this type if inverter pump so that owners can continue to drive their cars safely. *tr

 1. i bought a new prius in early march of 2005. i was coasting to stop (around 8-10 mph) for a yield sign and when i hit the foot on the brake, the vehicle started to accelerate. funny, but this problem happens only occansionally! 2. stimes the vehicles seems to come to a stall, at low speeds while making a turn or before coming to an dead stop. i personally have felt the vehicle going off the power during a turn, at low speeds <10 mph. 3. i tried to find any recalls on the vehicle, but was unsucessfull.

 Dt*: the contact stated the vehicle stalled on two separate occasions. the first time it occurred was on april 7th while driving at a steady speed of 25mph. the second time it occurred was on april 21st while driving at a steady speed of 5-15 mph. all the warning lights illuminated and the vehicle was pulled over. once pulled over, the vehicle would not go back into the drive position. afterwards, it stalled and would not restart. the stalling occurred 3-5 minutes after it was pulled over. the vehicle was towed to the dealership both times. the first time the dealer replaced the entire transmission. the second time the dealer replaced the inverter. on april 23rd while driving the dash board lights became inoperable including the speedometer, and the gear indicator. the contact alerted the dealership by phone who explained the problem was likely the circuit board and it was okay to continue driving the vehicle. afterwards, the vehicle began to blow out hot and cold air and the dealership was alerted again which explained it was okay to continue driving. shortly after it began to rain, the wipers were turned on, and the dash lights became inoperable once again. the vehicle is scheduled for inspection on monday may 8th.

 2005 toyota prius: in slippery conditions, when a front wheel slips, both wheels stop rotating and then the wheel that did not slip is given power. this takes about 1 second. during that time the motor has shut down, losing substantial forward momentum. if the second wheel slips,the process is repeated giving the original wheel power. the 1 second time interval occurs again and more forward momentum is lost. on a slippery hill, this basically stops the forward motion of the auto very quickly. if both wheels continue to slip,the auto just sits there , with the electric motor starting and stopping as the power is switched between front wheels. if there are cars behind yours, then backing up is impossible. if the wife and kids are in a bad neighbor hood and this happens,that could mean real trouble. the condition is totally unacceptable. all the prius' should be recalled and the traction control reprogrammed to allow reduced power to the slipping wheel, not zero power. this will tend to maintain forward momentum and keep the motor from shutting down. i spoke to the original dealer and they claimed no knowledge of the design flaw. *nm

 I took my prius in for recall, noted in pe05029, on or about december 9, 2005. i had no problems with the prius before the recall but did the recall because of the problems others were having. i had 25,000 miles with no problems before i took the car to toyota to do the recall. since then on two occasions, on or about january 14, 2006 and on or about january 16, 2006, i have had the engine start to rev up while at a stop light with my foot on the brake. i drive using only one foot so the gas pedal did not have anything. the engine seemed to rev to about 2000 rpms. this is an estimate on my own part from the sound and not a measurement. on the first occasion i turned off the climate control as i was proceeding to shut down the car and the engine returned to normal idle and then turned off as it normally would at a stop light. i left the climate control off and continued to drive when the light turned green and had no more problems that day. on the second occasion i eased up slightly on the brake pedal to see if the engine was actually propelling the car forward and the car moved forward but no stronger than it normally does with the electric motor. so, the engine although revving up seemed to be disconnected from the drive train. i believe i noticed on both occasions that the battery was fully charges with no white space at the top as usual. probably because the engine runs more anyway since the recall as can be noted by the loss in fuel economy. i reported it to the dealers service representative that i took the car in for recall and was told that unless it was a repeatable problem they probably would not be able to find anything. i requested that he report it to toyota anyway. *nm

 I have an early 2005 prius which has stalled i.e. lost al engine power on two occasions. i believe the stalling is intentionally designed into the software to protect the transmission. i think a design decision intended to protect the car is putting my life at risk. my early 2005 prius has stalled twice: once on the freeway at 80 mph when i had to jam on the brakes (someone cut me off) and again on surface streets at 30 mph when i floored it to accelerate suddenly. in each case the transmission's internal components would be under tremendous strain unless it disengaged. in each case all lights, headlights, indicators stayed on, the check engine light came on, the car continued coasting (as if put in neutral), and the car was unresponsive to the throttle and the gear shift. (in neither case did i hit the gear shift nor power button before the stall). in both cases i coasted to a safe spot (try crossing five lanes of 70+ mph freeway traffic at night while coasting). only after parking, turning off power, and restarting power would the car operate...at which point it operated fine. dealer couldn't find anything wrong...in fact the second incident was two days after my 30,000 mile service! they apparently took no action regarding the concern i expressed to the service rep with respect to stalling...he assured me they would check for all available software updates, but corporate told me today there is at least one update (relating to the navigation system) which was not downloaded, so apparently the dealer is not responding to this life-threatening concern. i called corporate today to start a case and was told they are unaware that this is a recurrent issue. this despite discussions in the press and on hybridcars.com. i am contacting you in case i am killed or injured before toyota figures out that this is a serious and recurrent issue. the first incident was around january or february 2005, and the most recent was monday sept 19 2005. *jb

 Driving 65 mph on the freeway, the low-fuel indicator light started blinking. approximately 15 miles later, still driving 65 mph, the engine shut off. dashboard warning light and check engine light illuminated. consumption was highlighted in red. the car continued to drive in electric mode at 52 mph for about 1.5 miles. when the battery was drained, the car came to a stop. after 5 minutes, i hit the power button to turn off the car, then again to turn on the car. the engine started and we drove to the next gas station, 4 miles away. toyota (1-800-331-4331) said to take it to the dealer. the toyota dealer said there is nothing they can do and toyota has not advised them on a remedy. dealer refused to provide me with this agency's name (nhtsa). i left a message with the prius team at toyota 3 days ago and they have not returned my call.

 The prius shut down, stopped using gasoline power, while i was in the passing lane and traveling 70 miles per hour in moderate traffic on interstate 40 in nashville, tn. the red triangle, check engine, vsc and a few other warning signals illuminated. i managed to avoid being rear-ended , pulled to the side of the road using battery power, shut the battery power off, and consulted the owner's manual. approximately 10-15 minutes prior, the add fuel light illuminated and the fuel indicator displayed a single bar. having driven the vehicle for the past 8300 miles, my wife informed me that we had about 2 gallons of gas, and could easily travel another fifty miles. the temperature was near 90 degrees. i started the vehicle and chose to drive it off the interstate. we traveled 2.5 miles and coasted to the side of the road as the battery depleted. i managed to slowly drive the vehicle to a gas station and refueled. the fuel tank could only accommodate 8.1 gallons of fuel; it holds 11.7. once refueled, the warning signals disappeared after 30 seconds, and we drove home. my wife took the car to the dealer, joe heitz toyota in clarksville, tn, the next day for an evaluation. the mechanic said that the computer indicated that the vehicle ran out of fuel. since there obviously was fuel in the tank, i pressed the service manager for answers. by the end of the day and after consulting with prius technical folks in california, the service manager said that the fuel bladder may have collapsed over the sending module thereby signaling the car's computer that it was out of gas, which caused it to shut down. he said toyota is looking into the problem and provided a lame solution; refuel the vehicle before it gets too low. this is an unacceptable answer and i implore the nhtsa to investigate this potentially deadly anomaly. it is only a matter of time before someone is in a fatal accident because the vehicle shuts down while traveling at interstate speeds.

 I purchased a 2005 prius in january 2005. at the time of the incident it had about 8500 miles on it. it had been performing well and i had been getting excellent gas mileage and the internal mileage indicators has proven to be very accurate. while driving on sc highway 31 at about 60-65 miles per hour the gasoline engine quit slowing me to about 40 miles per hour. the dashboard lit up with with warning signals including the red triangle, check engine, vsc, breaking system and i don't remember what else. a few miles before this happened, my fuel indicator started to blink, but was sure that the problem could not be gas since i have often gone many miles before finding gas in similar situation and knew from past experience, my milege,and fuel usage indicator that i had about two gallons left in the vehicle. this was an unfamiliar road to me so i continued to travel using the battery hoping that an exit would appear. the battery quickly became so depleted that i pulled to the side of the road. i tried to turn the vehicle off and found it unresponsive. after a few tries it did power down. i called aaa for assistance. during my wait, i was able to restart the engine, but it again failed within a couple of miles, but i was able to reach an exit and pull off. after the second failure, i tried to restart again and this time only got the red triangle and check engine light. aaa did add gasoline to the car, but the fuel indicator continued to blink and the bar never rose. the car was towed to sparks toyota in myrtle beach, sc who called to say that they believe that the problem is low fuel. i do not believe that it the case as this had not happened before when the low fuel indicator came on.

 While driving my 2005 toyota prius on highway at approximately 65 mph, the gasoline engine completely stalled but the electric motor continued to run allowing me to exit the highway, albeit at a reduced speed. i managed to drive approximately 1 mile to 1.5 miles until the electric motor battery was conmpletely depleted. the vehilce would not restart and i arranged to have it towed. while waiting for the tow service i tried to restart it a number of times and after 35 - 40 minutes it started and since then has had no issues. i believe that when it stalled on the highway the crusie control was set and there were between 1.6 and 2 gallons of gasoline remaining in the tank. this could have been a disaster if i was in heavy traffic in the fast lane as the car went from 65 mph to 35 - 40 mph in seconds! i also barely made it off of the highway and was actually sticking into the travel lane somewhat when the elctric motor also completly died. i notified toyota of the problem but no corrective actions were taken and they did not inform me of any issues.
