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.

 I have recently moved to pennsylvania, a state with many hills, and have found that on icy hills, the traction control causes the engine to shut down entirely when the wheels slip. this creates a very dangerous situation where there is no power at all to the wheels, causing the car to slip backward on the ice. i live on a steep hill and my car has almost rolled off the hill three times due to the failure of the traction control / engine. the prius, unlike many other cars with traction control, has no traction control shutdown/override switch. in researching this online, many other owners report the same problem. toyota refuses to acknowledge that there is a problem. this is very dangerous.

 Tl*the contact owns a 2007 toyota prius. the contact stated that whenever the front wheels began to spin in icy or snowy conditions, the engine completely shut off. the failure occurred multiple times while trying to drive up a hill or an inclined driveway. the dealer inspected the fuel injection system on several occasions and was unable to find the cause of the failure. the manufacturer stated that the vehicle was designed in such a way that the engine would turn off to avoid damaging the stability control system. the vehicle has not been repaired. the current mileage was approximately 36,000. the failure mileage was approximately 2,000. updated 3/16/10 *cn

 Indicator lights flashed. malfunction indicator lamp stayed on. at 2,644 miles, 12 v. battery dead & replaced. i was told to keep the gas tank half or a quarter full or the reserve gas tank would cause the car to run on battery. the battery might have died because the car sat too long before it was sold/at 8,879 miles, i went in. after filling the gas tank & taking out the nozzle, gas spewed & bubbled out. the car stalled while driving slowly & while in park. indicator lights flashed. the malfunction indicator lamp and master warning lights stayed on. it took 5 min. to turn off the car. i started the car. those lights stayed on. i was told i left the trunk door open & ran down the battery. (not true.) there is a gasket around the access hole and if a person is a little bit off, the gas will regurgitate. (i was not off & did not top off the tank.) they reprogrammed the computer. the gas tank had not been filled so i knew they did not fill the gas tank and try to recreate the situation as they said they would. i bought gas at a different pump. i stopped at a stop light. i could feel a loss of power in the car. when i pushed the gas pedal, the car would not move. i turned the car off and on 3 times before it would move. it crept slowly through the intersection as the traffic signal turned red. i took the car in at 8,936 miles. i was told if my problem is associated with the battery that was taken out of my car, it is not at repair person's responsibility because he did not touch my battery. when a battery is disconnected for a certain amount of time, if something is not reset, it could cause problems. then, he said no trouble found/my car stalled and/or had a loss of power. i took it in at 9,014 miles. no trouble found. i was told that my problems could have been caused by a faulty gas pump overfilling my tank. the gas station is new. the manager said the pumps were inspected. if there were a faulty pump, everyone would have problems. *tr

 Toyota has failed to recall the electric water pump in the second generation prius. toyota has recalled the first generation prius for a faulty electrical water pump, which is the same pump found in the second generation. while driving home from work, my check engine light turned on and i had to go to the toyota service to get it checked. after being told that it was recalled on the first generation, i looked up information online on if this was the same water pump. i then came across numerous articles and recalls on other toyota websites (in different countries) stating that the pump has been recalled. toyota however has not recalled any of these cars in the usa.

 I own a 2007 prius with 35,000 miles on it. we have been a 2 prius family for 6 years, so i am highly familiar with driving one. i have had three very frightening incidents happen in about the last 4 months in my car. each has happened in exactly the same spot during a commute that i do several times a week. i have been exiting from a freeway, going 65 mph, down a gentle downslope. when i exit (continuing the downslope) the engine starts revving at a speed that i never have heard during any normal driving circumstance. this is while i am braking to stop at a light at the bottom of the exit. i have had a car next to me roll down the window and the driver ask if i needed help. over the last 15 years i had done this exact exit thousands of times, in many different vehicles, and have never experienced anything remotely like this. each of the three times i shifted the car into neutral, but the high rev continued. the only thing that stopped it was to pull over and to turn the car off and restart. i immediately checked the floor mat each time and it was mounted securely exactly in place hooked on the mounts. this has happened three times, completely randomly. i took the car in to be serviced at toyota of berkeley on 2/2/10 and was told that until the car did this on a frequent basis that there was nothing that toyota could do. he checked the log for warning lights and there were no entries (i checked the dash each time this has happened, and no lights warning lights were on.) *tr

 Date: 02/09/2010 time: 10:01:20 creation date: 02/09/2010 creation time: 09:58:43 i would like to report a braking/traction control/loss of engine power safety problem with my 2007 toyota prius. the problem happens while driving on snow covered flat road surfaces (1 inch of snow), snow covered hilly roads (1 inch of snow), and bumpy road surfaces. when the traction control system (trac) engages on these road surfaces, i lose the ability to brake and also lose power to the engine simultaneously. i have had four (4) near-accidents due to this safety problem. 1.snow covered (1 inch of snow) going downhill (slight hill)- lost brakes after trac traction control system engaged was unable to stop car - went through stop sign. car went onto busy highway (50 mph zone) and would not stop. luckily no cars were coming and i avoided a very serious accident. 2. snow covered (1 inch of snow) going downhill - lost brakes after trac traction control system engaged and almost crashed into cars that were slowing down ahead of me. 3. snow covered (1 inch of snow) going uphill - trac traction control system engaged and i lost all engine power as i was turning left up a steep hill. i almost crashed into large rocks at the roadside. i was able to avoid a crash. 4. snow covered (1 inch of snow) driving on flat road surface. i turned off of snow covered road into a parking lot area. trac traction control system engaged and i lost the ability to brake. my car went at least 15 feet in the parking lot area before stopping. luckily there were no parked cars there and i did not have an accident. a recurring problem with trac and loss of engine power also occurs on the hilly road leading up to my house. when the road is snow covered (1 inch of snow) or icy the trac traction control system engages and i lose all power to the engine. it makes it nearly impossible to get my car up the hill due to the loss of power when trac engages! *tr
