 2005 gmc envoy bought in february of 2011. a few months later the fuel gauge only registers as empty regardless of how much fuel was added to the tank.
04/05/201179032
 Fuel gauge stopped working in april 2011. showing empty even when full. took to dealer. mentioned i heard trailblazers also having issue. was told no recalls. had to pay for repairs. finally got notice can get portion of money back. it took months to get portion of money back. i had to keep following up even though they confirmed they had my paperwork. strike 1. had car in for 100,000 mile service, 9/24 - 9/25/2012, only to go back later because of car seeming to now have issues accelerating and car was not reset after oil change. told needed engine mounts. disputed this as seems strange car was running and sounding fine before 100k mile service. went back and forth with dealer.took car back to have master tech check and also because oil gauge stuck in one spot. went in 12/31/2012. was quoted repair price for oil sensor and now repair quote not only has engine mount replacement but also quoted trans mount replacement. really....refused repair. strike 2 and 3. btw, also needed new tires. i went to other dealer approximately 35 minutes away instead to get tires. on 3/5/2013, on way home notice speedometer showing about 90 miles even though gps says i'm only doing about 67. exited interstate, shut car off and turned back on. no change. got home, turned car off. speedometer stuck at 20 miles. morning of 3/6/13, started car, speedometer stuck at 7 miles. worked full day. got home and it was back to zero after turning car off. current odometer is approximately 106,102. these people need to own up to their mistakes and errors. we spend enough money with them. grass may not be greener with other make vehicle but customer service goes a long way!!!!! will take a lot to get me to buy another gmc or similar vehicle.

 In december of this past year (2012) my 2005 gmc envoy began to have issues with the speedometer. i would be traveling down the a busy road at a traffic light barley moving and the speedometer would read 80mph. the needle would fluctuate anywhere from 20 mph all the way up to 120 mph and peg there. one occasion the speedometer would go back to normal 0 mph and work normally, but now that is an extremely rare occurrence. *tr

 As i was driving on the highway, i noticed that the speedometer was no longer measuring my speed, and was stuck on 70mph. the needle remained there, occasionally lowering itself in 5mph increments after restarting the engine, but then getting stuck again when driving. the needle generally buries itself at 120+ and does not readjust even by small increments anymore. my fuel gauge is also not working, reads on e regardless of how much fuel is in the tank, i wonder if these two problems are connected? *tr

 Almost dusk, high beams were on. thought i saw a flicker. got behind another car and saw that it was my lights. looked to my panel and my voltage was swinging between 9 volts up to 18-19 volts. turned all power draw off except my low beams. needle kept swinging and lights kept flashing. was 6 miles from home. i made it. there was a discharge to my system instead of continueing to charge. took to dealer. nothing found. 11-6-2012 it happened again. has happened inbetween also. very intermittant. had batttery & alternator checked at least 3 times. always good. after incidents, works fine until next time. never happened in summer. always when cooler weather. now that it is december, afraid to drive after dark. there must a bullentin or recall??? too many complaints on this problem. don't want to get rid of my car. engine is good. only 69,000 miles. is dealer just acting dumb? *tr

 As reported by many other gm customers my vehicle has experienced the same fuel gauge/sending unit failure. it began slowly with minor inaccuracies in fuel amount. then it quickly and steadily got worse until the fuel gauge doesn't work at all. i understand that gm acknowledges the problem, but refuses to pay the full price. i believe the nhtsa should force them to fully repair their faulty equipment which renders the driver blind as to how much fuel they may have. this could be very dangerous. *tr

 Repeat problems since car was purchased brand new at dealers. air /o2 sensors defective/replaced. defective fuel pump/fuel sensor/electronic gas gauge; flickering/dimming headlights; freezing/inability to control driver's side seat and controls. 1/4 of front instrument panel lights out; drivers side seat control lighting 1/4 out; check engine light and low fuel light on continuously since 1997. tie rods both replaced as well as both front sway bars. immediately following vehicle purchase, check engine light would continuously go off. i would call onstar at which point i was told to take car in for repair w/i 7-10 days (often told a problem w/powertrain or transmission) . at dealers service dept, told over and over again after tons of worry, concern and time spent, that electrical system on this car tends to trip/trigger check engine light and they would just reset it so after awhile, i began to disregard the light as i was in the dealership almost weekly. approx 2 yrs after purchase, filled up gas tank and fuel light showed low fuel. went back up to full, dropped to 1/2 and back to empty. went back to full after car was turned off and continued to do this. after about 2 weeks, constantly stays at empty. called repair shop and was told approx $700-800 to drop tank and replace fuel sensor which i could not afford and began to track odometer and refill tank after 200 miles driven after fill up. have been doing this for 5 years. jan 29,2011, i go for emission test. fail d/t low fuel and check engine light being on. go to mechanic, approx $950 repair. check engine light goes off...and back on next day. read thousands of posts online and am finding many, many envoy owners experiencing same problems as mine. these are safety issues and gm should issue a recall on entire fuel and electrical system. please call for questions/clarification.

 I was getting my tank filled with gas and the fuel gauge needle pegged out past full, then bounced down to empty. it did this three times then went back to full. since then it has continued to bounce around. the only way we knew if we had enough gas was to fill it and use the trip meter. the fuel gauge has ceased to move at all since april 2011. the check engine light has been on continuously as well since the incident. i love the vehicle but it is a major pain to keep track of the fuel when 3 people in the household rely on it. i looked online to see if there was a recall, only to learn this is a common complaint and nothing is being done about it. i priced a new cluster and it was over $500. needless to say we still have to keep track of the fuel with our trip meter. gm should step up to the plate and fix this issue. they had no problem taking a bailout. my family has been buying gm products for years, however, no one in my family will ever own another gm product if they can't do the right thing for their consumers, and do it now. not 5 years from now!!

 Instrument panel fuel level indicator shows incorrectly. at first it would show half tank or more when in fact there was less gas. now the fuel level indicator shows empty at all times. the audible fuel warning for low fuel also rings constantly. after running out of gas in the middle of nowhere on several occasions the vehicle was taken in to the local dealership. the repair was too costly. we were however charged a $100 fee just for the gmc dealer to look at it. we now track fuel using the trip computer. look online for some help i was amazed to find out that many, many, many people have and are having the same issue.

 The instrument lights regularly blink in and out on my 2005 envoy. there have even been times when the headlights blink off and on for no known reason. has happened a few times over the last 3 or 4 years. scary stuff! plus, i have read on several forums that this is a common problem with these vehicles. one fellow said he took it into the shop and they could not find the problem. recall - and now the problems with the gas gauge and check engine light. my husband was laid off from his job and we can't even afford the 1/2 that gm is offering to fix the thing in their recall. if they knew it was a failure of their equipment why are they not paying the entire amount?

 My fuel gauge stopped working 8 months ago, took to gmc dealer for service estimate. service manager said these fuel gauges always go out on envoys and the cost to repair was $578.00 (plus tax) - i choked and did not get repaired. 3 months later after trying to operate the vehicle without the fuel gauge - it became a nightmare to know if we had gas in the vehicle or not, i took it to an independent repair shop and they said we see this fuel gauge problem all the time on the envoys... they said the gmc parts were a rip-off and expensive, they would have to use gmc parts for the fuel gauge and they quoted $408.00 (plus tax) for the repair. the service manager for the repair shop said he could not understand why they have not had a recall on this since they have seen hundreds of gmc's with the same problem. he said we may want to wait on the repair to see if gm has a recall. on august 30, i received a written notification from gmc stating an issue with envoys and the fuel level sensor failure problem; however, gmc stated they would only cover 50% of the cost of repair. what a joke, 50% of a $600 repair bill for a problem they admit in writing is a scam to try and get as many people to pay for the repair ($300) before the gov't. mandates a recall... i called gmc and requested a 100% paid repair and they refused. i will be glad to forward the fuel sensor failure letter if you need ... can you please help? the are several hundred thousand owners of gmc envoys that would be very appreciative - thank you in advance...

 I purchased this car used with approximately 24,000 miles in 2006. within a year of purchasing the car the cluster panel (gauges) stopped working. i took the car in to have it checked and was told that there was no recall and that it would cost approximately $700 to repair as the entire cluster panel would have to be remove and replaced. after talking with co-workers with the same vehicle experiencing the same problem; i later discovered that there had been a recall on this issue but you had to be the first owner of the vehicle. after having the cluster panel repaired, my gas gauge has stopped working and i am told that the entire tank has to be removed for repair and that there has not been a recall on this issue either. the window and door lock system on the front passenger door also is non-operational. this vehicle seems to have several minor electrical issues but i am most disturbed by the fact that after spending the money to have the cluster panel fixed my gas gauge is still not working properly.

 The speedometer does not accurately record the speed while traveling for my 2005, gmc, envoy, slt model. it will indicate that i am traveling 20 mph or even 0 while on the highway and seems to increase my rpms while malfuntioning. this has caused seveal tickets as i can not personally track how fast/slow i am going while driving. this malfunction happens everyday. my oil gauge is also unable to read, it never moves and reads under the start of the meter (south) at all times, even when the vehicle is not started.

 One day my oil gauge stopped working. a few months later the speedometer stopped working and eventually every gauge in my panel stopped working. this all started around nov of 2008. i could not figure out what was going on. i checked all fuses, bulbs and wiring. now two days ago my head lights stoped working on low beam. nothing was found to be the problem. i recently found hundreds of envoy owners with the exact same issues and now know it is the instrument cluster panel. est cost for the part only $570

 Fuel gauge suddenly stopped working properly after fill up. moves from empty, to 1/2 full, to 1/4 full to empty, back to 1/4 full, back to empty. i can't determine how much gas in may tank. this could cause me to unexpectedly run out of gas while driving in traffic and cause an accident. this is apparently a very common problem in gmc envoy and chevrolet trailblazers. there is no warning in the owners manual or suggestion that the gauge and sensors be replaced. i understand that this is an expensive repair - between $600 and $900.

 For the last few months my 2005 gmc envoy denali has had repeated problems with the fuel gauge. after re-fueling the vehicle, the gauge will go to empty and illuminate the empty tank warning light. the check engine light also comes on. within a few miles the fuel gauge will begin to fluctuate wildly for a period of time, making it impossible to know how much gas is in it. the fuel gauge sometimes begins to operate again after the car has been driven for a few days. car has become unsafe because it is difficult to determine how much fuel is in it and empty tank sensor cries wolf. also, the fuel gauge has begun to register a full tank when really the gas tank is near empty. once you start driving the fuel gauge begins to fall slowly until about 10 minutes later it finally registers the proper gas level... i've thought my husband filled up the tank and almost run out of gas because the fuel gauge didn't tell me i was out of gas until i was on the highway stuck in traffic - away from a nearby gas station. the trip odometer is not an exact science so it cannot be relied upon. (mpg vary depending out temperature, city vs. highway miles, mph, etc). message boards show that this is a common problem and eventually lead to the car stalling unexpectedly, even during highway travel. see http://www.aboutautomobile.com/complaint/2005/gmc/envoy/fuel+system.

 I have a 2005 gmc envoy. i have had several issues with the ignition switch, the fuel gauge sensor, and the rear hatch. i have replaced the ignition switch four times, purchased a new battery, and a new starter, as well as a fuel sensor. i still have intermittent issues with my car not starting for no apparent reason and stalling out while driving and especially when decelerating. the stalling is a severe safety hazard as i travel very busy highways during my daily commute. my wife and children, as well as myself, have been stranded many times when the vehicle would not start after operating fine prior to turning off ignition. we have had the vehicle in the shop many times and have been told there is nothing that can be done for us because they have no idea what the cause is. at this point, i do not allow my wife to drive the vehicle anymore out of fear for the safety of her and my children. this is a significant stress for us that i feel we should not have to endure.

 I was on my way to work during the winter months and my blower fan stopped working. at first i could't see very good out my window and my headlamps started dimming. there is an overload someone near the blower and my vehicle only has 70,000 miles on it. i think this should be a recall because you need heat and light to see when you drive and without it can cause accidents. i was down in a ditch when mine went out and thank god someone was watching over me. the price you pay for a nice vehicle their should be no defects with under a 100,000 miles. i have still from this day haven't had the money to replace it because my truck payments and insurance break my budget.

 The gas gauge stopped working and shows that the vehicle is on empty. the low fuel' indicator on the dash will blink randomly and ding to draw my attention to it. the gas cap was replaced a week later but the problem has not been resolved. it continues to read empty. since then the speedometer has also stopped working. the speedometer hand has completely dropped below the 120 mph mark, although for a few weeks it would register that i was driving much faster than the speed of traffic around me. moreover, it would register 30 mph when the vehicle was completely stopped. yet, it has since stopped working altogether. the vehicle has also recently stalled in reverse and several times has surged/accelerated quickly when i am driving slowly and push the gas pedal to accelerate. i have an appointment with the local gmc dealership and have called the national gmc dealer to document my complaint(s). *tr

 2005 gmc envoy gas gauge does not work. car had 42000 miles when it quit. car now has 50200 miles on it. gas gauge reads empty and sometimes will float just above empty even with a full tank of gas. car has left family along side road while waiting for help. should be a recall as there is thousands of complaints on this issue. *tr updated 02/01/10 *bf updated 02/02/10.*jb

 The speedometer constantly shows different speeds. will be driving down expressway at 65mph and next thing you know it shows 90mph so you slow down 65 again and realize that everyone flies by. the best i can figure is it will suddenly show a different speed than one is actually going from 20mph less to 40mph more. different every time. *tr

 There was ignition switch failure while driving the vehicle. the power steering and brakes gave out, the engine shut off, and all the lights on the dash came on. it resembled the car running out of gas without doing so. after i pulled off the road with great difficulties, i put the car in park and the vehicle got stuck in it. the engine would not turn over after this occurred and needed to be towed. there is no release switch which the tow truck driver said there should be so he could get it onto the truck, so the vehicle has to be drug with the wheels locked onto the flatbed and then pushed off in the same manner. we paid to have it fixed and it has now happened again 5 months later. there are many reports of this online and it is not just with the gmc envoy denali it also includes the chevy trailblazer and possibly other vehicles manufactured by gm. there was one person online that said they keep spare ignition switches in the vehicle and the tools to swap it out because of how frequently it happens. the dealership replaced the part and it is not available as far as i know, because it was not returned to me. the vehicle was a 2005 gmc envoy denali. *tr

 I have a 2005 gmc envoy. the envoy began experiencing problems at approximately 58, 000 miles when the gas tank began reading empty no matter how much gas was in the tank. eventually, after much complaining to my local dealership they stated they would only repair the problem if i paid for half of the repairs. i refused. later, at approximately 80,000 miles, my speedometer began malfunctioning. the speedometer works intermittently, just recently it was stuck at 120 mph even in park. now, the battery gauge has begun to malfunction. the battery charge ranges from the lowest to the highest with no real rhyme or reason. it is apparent by reading on the internet forums that this is a major product defect as it happens to many, many gmc owners, especially 2002-2005 envoy owners. i have filed complaints with gmc directly and received responses that are not satisfactory. these items should be a recall effort and repaired by gmc as they are clearly product default not just general ware and tear of the vehicle. these problems are costly and present safety issues while driving. *tr

 Gas gauge has not worked since 2007. headlights and some dash lights as well as ext temp gauge sometimes flicker. no positive response from dealer for gas gauge. was initially told headlights were supposed to do this, a feature. i asked them to document this for me, they said they would look at it. replace body control module, no change. said it could be this or that, but out of warranty at my expense. i told them i would pay for it, but if it did not fix the problem i would not. they refused to work further on it. *tr

 I have a 2005 gmc envoy that has just started having issues with the fuel gauge. i have filled the gas tank and the gauge reads empty with the fuel light on. then 10 minutes later the light goes out and it reads that i do have fuel. then a little later it starts going down and reads empty again. i have re-stopped to get gas to find that the tank is full. this is wrong and there should be a recall on this item. it draws the driver's attention away from driving and must have caused accidents somewhere in the usa. *tr

 I have had my 05 gmc envoy for several months now and have taken it to be repaired at least once a month! my issue is with the electrical system and the headlights and console flashing at night. i have taken it to the dealership twice and the first time they checked the battery, some cables and gave it back to me saying they could not find anything. the second time i took it back about a month later because the light were still flashing. the dealership had it for 2 days and told me it was my alternator. i did not believe them and did not get my alternator changed ($675.00) and my car has been starting and running fine. my headlights still flicker, but there is nothing i can do about it. i have read several other complaints about this and most of them go through a new battery and alternator and it still does not fix the problem. this is something gmc needs to look into and fix because it is a huge safety hazard. *tr

 The check engine light kept coming on and i took it to the dealer for repair and was told it's ok. forget it. on 01-09-2009 while traveling on texas highway 60, i had the cruise control set for 70 mph. traffic was normal but continually passed me as if i was going slower. i pulled over at a convenience store and parked the vehicle. the speedometer registered 45 mph in park. i continued home gauging speed by the other traffic. the vehicle was parked. on 01-14-2009, my wife and daughter were in the vehicle returning from school. the speedometer appeared to be working. at approximately 3:00 pm while driving home, the electric door locks began to lock and unlock themselves. at the same time, the a/c went to maximum heat and high blower. my wife stopped the vehicle and put it in park. the side curtain air bags deployed, striking my daughter in the left temple resulting in a mild concussion. onstar notified the police of a collision. i contacted the dealer who referred me to gmc customer assistance. the agent told me that this kind of thing happens when traveling too fast and turning too sharp. an investigator was dispatched to gather computer information and determine if there had been a collision. his results were there was no collision and the bags deployed per command from the vehicle control system based on the vehicle traveling 20 mph and turning too sharp. the vehicle was actually traveling 20 mph on a residential street in a straight line. turning right would have resulted in going through a fence and left would have put the vehicle in a park. gmc refused to investigate the discrepancies between the computer and the driver's account further. i contacted a local gm dealer who has as much concern about this incident as i do. no repairs have been initiated to date as it is unclear what is at fault. several gm technicians and service managers believe there is a problem with the vehicle control system but are unable to proceed without approval. *tr

 Tl*the contact owns a 2005 gmc envoy. the contact stated that he was experiencing issues with the headlights. when his wife would drive the vehicle at 50 mph, the headlights would get dimmer and dimmer and then brighten again. on one occasion, the lights turned off completely and his wife had to drive home with the hazard lights flashing. the issue occurred intermittently. the contact took the vehicle to the dealer at least four times and they changed the switches and recalibrated the lights. the repairs caused other failures; therefore, they recalibrated to the original lights. the dealer stated that there was no remedy for the failure. the manufacturer stated that they would start a case for him and call him back. the current mileage was approximately 41,000 and failure mileage was approximately 23,000. updated 11/14/08 *cn the check engine light illuminated. the dealer replaced the o2 sensor. updated 11/18/08. *jb

 Purchased a used (had previously been gmc exec's) 2005 gmc envoy in september 2005. since january 2007 we have experienced multiple issues with the vehicle. we have had problems such as the headlights dimming on and off while we're driving, the airbag sensor saying off even when my wife is sitting in the passenger seat, and the driver side power seat would move up, but wouldn't move forward or backward. however, the biggest problem and safety issue has been the vehicle shutting off while in the middle of driving it. there have been numerous occasions where we have been on back roads, rush-hour freeway traffic, etc. and the vehicle shut off, lost all power including power steering and you can't pump the brakes-you have one shot to hit the brakes. last thursday, march 6, 2008 this happened to us 5 times in one day!! my wife was on her way home from a job interview and the vehicle shut off on her 3 times. then, it shut off on her again when she was driving to pick me up from work. on our way home it shut off for the 5th time that day and it did it in the middle of heavy, rush-hour traffic on the railroad tracks! this is an issue that needs to be fixed. we keep this car in tip-top shape, properly maintained. it is barely 3 years old and having these types of problems is not right. gm needs to issue a recall on this asap. this needs fixed immediately...and apparently this is happening with a lot of, if not all, envoys. one envoy...that could be a fluke, but more than one, even just 2 is a duplicate problem and should be recalled. *tr

 I purchased a 2005 gmc envoy in september 2005. in the past year (since january 2007, at least), i have experienced several problems with my vehicle. the first problem is with the headlights. everytime i have driven the vehicle the headlights appear to dim/flicker and then return to normal. this has resulted in oncoming vehicles turning their bright lights on me thinking my brights are on when in reality my headlights are dimming and then returning to normal. the second problem concerns the passenger side airbag. anytime a certain weight limit is met or exceeded the airbag sensor is supposed to switch to on, but there have been several occasions when someone was sitting in the passenger seat and the airbag sensor hasn't recognized it. third problem, driver side power seat failure. there have been several instances when i have tried to move the driver seat forward, but nothing happened. the motor sounded like it was grinding and wanted to move, but the seat would not move forward or backward. the most extreme problem to date has been with the vehicle completely shutting off without warning while in the middle of driving and then not starting or even turning over at all. every single day for, at least, the last month when i go to start the vehicle it fails to start and it takes a minimum of 1 hour to get it started. one instance in particular when the vehicle shut off without warning was while my wife and i were on the freeway. without warning the vehicle shut down and we were forced to pull onto the shoulder. we sat there for almost an hour in temperatures of 13 degrees trying to get the vehicle restarted. there have been countless complaints and reports of other envoy owners experiencing these same problems. some dealers have actually said that these failures/problems are normal!!!! what!?!?! are you freaking kidding me?! since when is it considered normal when so many envoys are displaying these same problems? *tr

 Tl*- the contact owns a 2003 gmc envoy. the headlights, dashboard, and tail lights flashed randomly at any speed, this failure started in october of 2006. the weather and time of day were not factors in the failure. the dealership said that the failure was normal. there were tsbs for the failure, as well as for several others. the fuel neck had been replaced twice due to a design change. the seal around the licenses place holder came loose and had to be replaced. the brake pedal was squeaking, the contact took vehicle for service on three occasions, and replaced the serpentine belt twice, an airbag sensor, the rear wiper arm, the oxygen sensor twice ,the first time at 7000 miles. there were cruise control failures, when the contact tried to accelerate it hesitated and then surged. the weather stripping on the rear doors has been repaired three times. the abs would skip on a bumpy road and would not engage. at one point the contact could smell fuel in the passenger compartment and vehicle had very poor gas mileage, the dealer stated that there was nothing wrong with the vehicle, but air valve became stuck and would not close. the rear door hinges squeaked. this winter it won't go to full voltage until a minute elapsed after the vehicle has been started. the original failure mileage was 3829, and the current mileage was 23700.*ak the brakes were inoperative, the belts squeaked, there was a problem with the abs, the air bag light illuminated, the cruise control didn't work properly, the rear wiper would only wipe the middle of the back windshield. a new fuel neck was installed. updated 03/15/07. *jb

 I have an '05 gmc envoy slt. i've only owned it six months, since nov '05. i've dealt with flickering headlights and dash lights until just a couple of months ago. i had that issue looked at while installing step rails. i was told this was a typical issue with envoys and they only needed to 'tighten' some bolts. when i initially mentioned the problem i also commented that i would get the 'shock' of my life while exiting the envoy and asked if it could be a grounding issue but they said no. anyway. the problem was solved for a few days but it started all over again and it gets worse as time goes on. before i took it in the first time it was so bad i could feel the engine surge in unison with the flickering of the headlights and dash lights. i feel this could be an extreme safety issue since it involves the headlights and it more noticeable in the dark hours. *jb

 (2005 envoy) about 1 month ago i noticed that my headlights were dimming while driving at night . this happened sporadically. when the lights dim, the heat slows down as well. the interior lights occasionally dim when this happens, too. my husband and i thought it might be the battery and started to look at the battery gage, while one of us kept an eye on the lights. this problem has happened about 7 times over the last month. last week it happened about every 2 minutes while driving down the road. very scary, as i thought the truck was just going to shut down. i took the truck to my gm dealer and the mechanic said that there is nothing wrong with the truck. the battery, alternator and wires were fine. he stated that with new vehicles and everything that is run in them this is normal. although he also stated that he has never seen this problem before. their computer told them that nothing needed to be fixed. we have no aftermarket products in the vehicle and the only things running were the heat and radio. *nm

 On the night of saturday (at 9 p.m.), december 10, 2005, i drove my gmc envoy slt to michael's. when driving through the parking lot, my daughter and i heard a loud grinding noise from the underside of the vehicle. we parked the car, turned off the engine, then turned the vehicle on again. several icons that had never been displayed on the dashboard screen appeared, and my vehicle's clock reflected 12:00. the clock was set for the correct time initially, and never tampered . we shopped for 20 minutes and returned to the vehicle, started it up and again several icons appeared. the clock said 12:00 though it was 9:30 p.m. we drove through our neighborhood viewing some christmas lights for about 10 minutes. as i pulled onto our driveway and began breaking to stop the vehicle and and park it outside of our garage, it did not respond to breaking. when i pushed the brake pedal down harder, the vehicle continued at the same speed. i screamed that we were going to hit the garage door, and at that moment felt the vehicle accelerate although i had the brake pedal pushed down all the way. it slammed through the garage door, i quickly shifted into park and shut off the engine. my front and my daughter's front passenger door could not be opened and we smelled gas. my husband called 911 and emergency vehicles responded. they determined it should be safe but asked the furnace be turned down so that it would not cause any combustion and to keep the area ventilated.. the garage door was totally demolished, and drywall damages in several spots. a technician from overhead garage doors removed the remnants of the door. my daughter's car had minor paint and dent damage as it was in the garage already. gm's roadside towing hauled the envoy onto a flatbed to take to the dealership. we explained the accident to gm when we contacted them for roadside assistance. the vehicle is now at our dealership, andy mohr, noblesville, in. *nm

 Dt: consumer owns a '05 gmc envoy and has difficulty towing a trailer within gm rates, gm states that his envoy can tow a weight of 5,800 pound capacity, however he feels the vehicle is unable to maneuver a travel trailer of 3,400 pound capacity. the consumer has been to the dealership twice for this. the dealer stated there was nothing they could do. consumer has pulled the trailer with other vehicles and it pulls fine but when attached to the envoy there is a problem. consumer feels it is not with the suspension of the vehicle but within the engine which is a v6. when pulling trailer for a distance as little as 2 miles the engine heats up, and he experiences a loss of speed and engine the bogs down to 30 mph. envoy is equipped with the 373 axle ratio and can not pull an enclosed 24ft travel trailer on it's 6 cylinder engine. the 2nd trip to dealer, the service manager did duplicate this problem and suggested the consumer needed a v8 engine. also, there is a electrical problem that only occurs when the engine is running. consumer gave examples of automatic door locks unlocking by themselves and the anti theft system enabling itself resulting in a shutdown of the vehicle. took to dealer 10 times for this problem. dealer could not duplicate problems. the dealer said gm would not authorize repair unless they could duplicate problem. has contacted gm customer service at least 100 times for these issues without any luck. no repairs or corrections as a result. consumer is still experiencing these problems as a result. *jb
