Engine And Engine Cooling Problems of GMC Envoy - part 2

Accelerating while entering a freeway, took foot off the gas and the vehicle continued to accelerate. Applied brake but vehicle continued to accelerate. Put vehicle in neutral to try and slow down and again applied brake. Vehicle began to spin to the right and we hit the guard rail, hitting the passenger rear bumper and the driver's side front bumper. Side air bags deployed. Car spun into the middle travel lane and began to spin around. Car was slowing down and was able to turn car off. Fortunately no other cars were involved. An off duty sheriff's deputy stopped and said he noticed smoke and thought the car was on fire but no fire occurred. When state police arrived they asked us to move the car to the break down lane. Was able to put car in reverse and backed car to breakdown lane. Tried to put car in drive but car wouldn't go forward.

Was driving and service engine soon and reduced engine power loss came on. The car basically starting shutting down but I was able to coast out of traffic before it stopped completely. Turn it off, back on several times, until the lights went off then drove it home. I've replaced the throttle body twice and the gas pedal for the sensor located behind it. Went from happening sporadically to almost everytime I drive it. Can't drive 3 miles without reduced engine power loss coming on. Now there's about 155,000 miles on the vehicle and it's happening all the time. Needless to say, it's sitting on the driveway. I'm aware other customers are having this same issue from reading comments online. I don't understand why gm has not done a recall to fix the issue. Perhaps it can't be fixed.

The oil pressure gauge is reading above 80. Had oil changed immediately. Was told that there have been complaints regarding the mis reading of the instrument panel. Contacted gm and was told that at this time they are not covering the repairs and that it is the consumers responsibility to replace the engine sensor system. Gm has some of the rudest and nastiest customer service representatives. I had to call 3 times in one day. They even hung up on me . I spoke with jonathan, connie and veronica. I asked about the safety of the vehicle and other potential problems, such as engine fire or entire system shutting down and not responding. They had absolutely no answer for me other than they are not covering the cost of the repair.

Rough idle while in park and while shifting to second gear. Engine light flashing, oil in spark plug wells, cylinder misfire on cylinder #4. Changed spark plugs & wires, this did not remedy the situation. I had the SUV for 1 month and the drive train went bad. Two months later, I got my truck back from the mechanic because parts needed to be certified by a gm engineer. I have had nothing but mechanical failures since 2010 when I bought the vehicle. Now I have at least five troubleshooting codes and now I'm being told that the cylinder head needs replaced. This shouldn't be happening and I know now that I will never buy another GMC product ever again.

I got into the truck to leave work shifted into reversed half way thru the turn the wheel locked up and truck shut off. I put in park and restarted no problem the next day same thing at a red light wheel lock needs to be restarted. It sounds like the same issues on the recall but my truck is not on the list.

Ive had car one month to the day were do I start . The car cuts out while driving. Shows codes one sec. Next sec I have several looks clean but so many probs I reall feel fucked. I purchesed a lemon.

It started with engine misfiring causing engine to jolt which damaged #4 coil pack seal to failed allowing water intrusion. In 2008, the GMC mechanic replaced all six coils seals but in 2013-present p0440 engine code is a leak in the evaporative emission (evap). Loose fuel tank filler cap is the most common cause that triggers the p0440 code. I failed a few smog check spending hundreds of thousands of dollars yet my problem still existence. I've contacted the bureau of automotive repair because purrfect auto in fullerton,CA lied about fixing my car. The bar made purrfect auto replace the gas tank and gas cap yet the engine light is still on displaying code p0440. Its been 14 years and I'm still dealing with this problem.

Luckily I stopped at a traffic light and the car quit. I put it in park and tried to re-start it but had nothing. A police officer pulled up behind me and radioed for a tow truck. They took it to the dealership and $300. 00 dollars later said it was the ignition switch. They gave me the old switch and I still have it. Now I would like to know what would have happened if I had been on a major freeway traveling at 75-80 mph and the switch were to go out? g m is just recalling certain vehicles, what about all the rest that still have the same thing wrong with them. Is it that you have to loose your or someone you love's life before they are made to fix faulty parts? maybe they should be made to produce parts up to american standards and not third world country standards. Thank you.

While driving another motorist saw smoke coming from rear of vehicle and got vehicle stopped on side of road at which time the engine compartment was engulfed in flames. Called fire dept and police. Fire spread through the hearer box into the vehicle and across dash until it began burning the headliner. Fire dept put out fire but was a total loss. There was no indication on instrument panel of any problems (all gages showing normal readings).

In the rear compartment of my 2006 GMC Envoy denali there is a compressor. There must be a leak because my car looks like a low rider in the morning until I start it and the compressor comes on and in about 3 or 4 minutes it is back to it's normal driveable height. Has there been this problem with anyone else and is there a recall to fix this problem?.

The contact owns a 2006 GMC Envoy. The contact stated that when coming to a stop, the vehicle would shake violently. The vehicle was taken to an independent mechanic, who diagnosed that the cylinder head valve seats were wearing out prematurely and as a result, the cylinder and the valve seats needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 98,000 and the current mileage was 138,000.

We were again driving on interstate 5 at 60 mph when the engine just stopped. We were once again able to coast to the side of the road. This is the 2nd time our Envoy just stopped running at 60 mph. Again, the mechanics could not figure out why this happened. I happened one more time, but I do not have the date. So that makes three times our 2002 GMC Envoy suddenly quit running while at a high speed on the freeway. We are concerned this is an ignition problem like with the other gm vehicles this has happened to.

Engine wouldn't crank at times. Starts normally when it does. After about a week of having this problem I took a the car in for service. Diagnostics determined the ignition switch was bad and should be replaced. I had the ignition switch replaced 14 months and 6070 miles prior to this incident. They replaced the ignition switch. The part was under warranty but diagnostics and labor was $220. The first ignition switch failed at 65-70 mph on the freeway. I understand that gm has recalled ignition switches on several models but the Envoy is not part of that recall. Obviously my vehicle has the same problem as the recalled vehicles, why is it not part of the recall? this is a very dangerous problem. Since the rest of the electronics are connected to the ignition I have no safety equipment such as air bags. If I would have been in an accident, it could have been fatal.

The contact owns a 2008 GMC Envoy. The contact stated that the check engine warning lamp illuminated on the instrument panel. The vehicle was taken to the dealer and they stated that the seal that was on top of the fire wall was damaged. As a result, the water was sipping into the engine compartment and was getting on the coil packs and the plugs. The vehicle was not repaired. The manufacturer was not notified. The failure mileage was 59,000. The VIN was unavailable.

While traveling on the interstate this morning, the speed on my 2006 GMC Envoy dropped suddenly and I had to pull to the side the road where the car completely stopped. I notified onstar, who performed a diagnostic test and indicated there was an issue with the fuel delivery system. The car would start up again, but only momentarily and the engine would die again. I had it towed to my home and am contemplating what to do at this point in terms of repair. There was another issue just over 2 months ago when the fuel gauge was not working and it ran out of gas. No indicator light ever came on. There was at least 15 gallons of gas in the vehicle today, as I had just filled it up a few days ago and had not traveled far. I have filled it up every weekend since the indicator light incident. About 2 years ago, I had to replace other parts related to the fuel. . Possibly called a fuel regulator?? which was mounted to the gas tank. This occurred at 37,000 miles. I was denied an inspection sticker because of an issue with emissions and had to replace that part as well.

Tl- the contact owns a 2006 GMC Envoy denali xl. The contact stated that the vehicle failed to accelerate over 40 mph. The contact also stated that the engine and the low fuel warning lights illuminated although the fuel level was at max. The vehicle was taken to the dealer where the contact was informed that the throttle body and fuel pump needed to be replaced. The failure mileage was 128,623 and the current mileage was 138,182. Mah.

Without any warning/indication [nothing light up on dashboard]; the car started jerking & slowing down. It sounded like rocks was rolling around under the hound of the car. I pressed the onstar button [which the car has been monitored by for the entire time of ownership, and all reports have always been egine/drivetran/transmission good] and the was told there was and engine misfire. All maitnenace has been kept up to date; and again the car monitored by onstar and never have I received a bad report. I donot understand how/why something like this could happen w/o any warning! I tried working with the local dealership; GMC fianncing office ~ and nothing!! this car is paid for & I cant afford the repair cost associated with it. Thia has to be some sort of defect!!!!!!!!!!.

The contact owned a 2003 GMC Envoy. The contact stated that while driving 30 mph, the engine compartment engulfed into flames without warning. The fire department was notified and no injuries were reported. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure and did not offer any assistance. The VIN was not available. The vehicle was declared destroyed. The failure and current mileages were 79,000.

Driving on the highway the vehicle suddenly read empty on the fuel gauge, then the panel said low oil pressure shut off engine. I ran out of gas on a busy highway passing lane almost causing a bad accident with my 5 year old in the back seat as I could not tell my fuel level. The fuel gauge would work sporadically over the next few days and the low oil pressure would go away and come back. When I had this checked out it was thought to be the oil sending unit so it was changed along with the fuel sending unit. The fuel sensor was resolved at a cost of $300 but the low oil pressure came back on even though oil was well maintained. Suddenly on 3/1/2012 the engine ran load when started up. I had towed to the shop where (gm where they determined the engine was no good. I had it towed to another shop that determined the engine was no good as well. I had to pay to replace the engine almost $5000. I then looked online for this issue and found a website trailvoy. Com (represent chevy trailblazer and GMC Envoy). Here I found 1000's of post of people having the same issues looking to file law suits and wondering why we can have no recall on this dangerous vehicle. There ore 1000's of people having low oil pressure, dead engines with low mileage vehicles, run out of gas on busy roads such as myself and much much more. The gm issues we've experienced and are experiencing has been here long before the current issues of gm vehicles. How can we get someone willing to have this vehicle and issues on the recall list and get reimbursed for the 1000's of dollars spent to repair this very defective vehicle. If a petition will do it please shine some light on this. I had received post on the forum from numerous people willing to join a class action suit and many were consulting attorneys on how to move forward with this. This is a major issue that we desperately need the NHTSA to look into.

On Thursday 12/27/2011 on my way to work pulled into hess gas station put my truck in park look up and I was rolling back. . . Look at the gear shift and it was in park but on my dashboard the truck was in 1st gear tried to pull it out of park by the hand gear and it kept rolling back and forth then it finally lock up in park but still on the dashboard it said it was in 1st gear unable to change gears, had to have my truck towed to where I purchased it from autoline in jacksonville fla. Found out the shifter cable pop in half had to have it replaced purchased the shifter cable and shifter assembly costing just for the parts over $200. 00 at 292. 00 labor I only had the truck 3 months and since they claim it was wear and tear it was not covered under my extended warranty I purchased. This was a very scary morning glad I was not driving it and pulled over to purchase gas that morning. What I don't understand is why is this considered wear and tear. . . . .

The cataytic converter broke into pieces and the car would not go above 25 mph.

We were driving on interstate 5 at 60 mph when the engine just quit. We were able to coast to the side of the freeway. Had to have the Envoy towed to our mechanic. They could not find anything wrong with it. We now believe it was an ignition problem like with the other GMC vehicles.

Reduced power light came on when on the highway. Almost got hit by a semi. This has happened many times. The engine has only 8k miles since engine was replaced under warranty.

The contact owns a 2006 GMC Envoy. While driving approximately 35 mph, the contact noticed smoke escaping from the air conditioner unit. The contact stopped the vehicle, looked under the hood and noticed that the resister and motor wires were melted. The vehicle was not taken to the dealer for diagnostics or repairs. The approximate failure mileage was 100,000.

2005 GMC Envoy xl has several issues with the instrument cluster. The battery and temperature gauges are reading off the scale past their maximum readings. It should also be noted that this vehicle also had issues with the fuel gauge sending unit and the engine thermostat.

While driving at approximately 65 mph on the 405 freeway, the a/c was turned on and the engine died. Previously about 3 days earlier, while stopped at a traffic light, the a/c was turned on and the engine died. Following both incidents, the a/c was turned off and the engine was restarted without further problem.

The guages have gone crazy, eng light pops on and off, abs light?, I am afraid that the computer may shut down while driving? have been told mechanic that the entire instrument cluster will need to be replaced and reprogrammed.

2005 GMC Envoy xl - my car has died on me while going down the road on five different occasions. It has been to the dealer twice now, and they say they can't find anything wrong. I feel very unsafe driving this car, and I am afraid my family or someone else could get hurt. Looking online, I have found other Envoys have done the same thing. One time it did lead to a death. I am hoping my complaint may be the one needed to do something about this dangerous problem. Each time someone has taken their vehicle in for this problem they get the same response I have gotten, nothing done!! my vehicle is still under warranty and I will continue to take it back in hoping they will find the problem. Please investigate this. It's very scary to be going down the road and your car just dying on you for no reason.

I own a 2002 GMC Envoy. For the past year or so, I've been having trouble whenever I stop at a red light, the car starts to shake and sometimes turns off. I usually turn the car off and start it up again. On Monday, July 27th, I was driving when my car suddenly shut down. Luckily I was able to get the car to a safe spot and no further damage was done to my car or other property. I tried starting the car again and it would not start. I had to get the car towed to a nearby mechanic. Once there, the mechanic looked over the car and determined that it was the computer engine and that it was under recall. He had me call GMC so that I could report the incident. When I called, I was told that there was no recalls on my exact car but that she would contact the mechanic and get some more information. After a couple days of waiting with no vehicle or call from GMC, I finally get a call back from the mechanic telling me that he spoke to the GMC representative and that they would be calling me back to set up a date and time to take my car to the dealership to have fixed and that the recall information was correct. About an hour later, I received a call from GMC and she told me that they were not going to cover the repair. Never having to deal with this before, I was completely confused as to what was going on and why GMC was not covering it. This is a huge safety concern for me and I would like to get some resolution from it.

The contact owns a 2004 GMC Envoy. While driving approximately 45 mph on normal road conditions, the contact rear-ended the preceding vehicle. There were no damages to the vehicles or the occupants. He pulled over to the side of the road and noticed smoke suddenly appearing from the front end of the vehicle. Immediately, the passenger compartment became engulfed in flames. The contact safely exited the vehicle. The police and fire departments were called to the scene and a report was filed. The vehicle was completely destroyed and towed to a collision center. The insurance company was notified; however, the cause of the failure has not yet been determined. The VIN was unknown. The failure and current mileages were 75,000.
