When backing the vehicle to leave a local restaurant, driver struck vehicle behind her. This happened so quickly that it was unknown to the driver how the vehicle traveled so quickly that driver had not even had a chance to turn the steering wheel to avoid striking the other vehicle. Driver placed vehicle in drive to pull over to assess the damage. When placed into drive, the vehicle lurched forward and continued to accelerate despite the brakes being applied. The vehicle struck a brick restaurant. Damage was also done to the interior bathroom of the facility and the business had to close to assure safety of it's staff/customers. Witness states the vehicle was obviously lurching and appeared to have a mechanical problem. The driver's foot bounced off of the brake pedal on impact lodging it underneath the brake pedal. It was also noted that neither front airbags did deploy. Driver did not seek medical attention however driver's foot was badly bruised.

On July 28, 2014 I was going down a hill and the engine shut off completely. Fortunately I was only going approximately 5 mph and was able to coast across the main street and was able to coast into a parking spot. I tried restarting my Envoy with no luck so I had the truck towed to the local GMC dealership and was told that the ignition switch had gone bad. I hate to think what would have happened if I was going faster or going down a steep mountain because where I live I am surrounded by mountains. I am not sure if anyone else experienced this problem with a similar vehicle. I do know that other GM cars and vehicles are being recalled for this same situation but was told that mine is not under a recall at this time.

My 2005 GMC Envoy has started experiencing a knocking sound in the right rear passenger side. It starts approximately a minute after the vehicle starts and stops within a minute or so. It happens when the car is moving or idle. This started yesterday evening. Not sure what is causing it. Everything is running fine in the vehicle. There must be other similar complaints and resolutions.

I have had a problem in the past with the fuel gauge reading empty continuously as I have read from many other complaints. Recently I experienced a problem with the oil pressure gauge. At first the check engine light appeared intermittently and then the oil pressure gauge dropped to zero, at which time the message in on the lcd reading said "stop engine" and "oil pressure low". I immediately went to my gas station and checked the oil, which was only down a 1/4 tank. My mechanic stopped the car and started it again and the oil pressure gauge reset itself but once I started to drive the car again, the oil pressure dropped. My mechanic believes it is another sensor problem like the fuel sensor but is not completely sure. I only started with this issue today but it is more worrisome to me than keeping track of how much gas should be in my tank. I am curious to know if others have started to experience this problem. I have had the car since it was brand new and have drive 79000 miles. I also had a major issue with the suspension system with I believe is common in this vehicle.

2005 GMC Envoy would not pass state inspection after 3rd year; fuel meter no longer works. Dealer wanted $400 to repair. Dealer wanted $1600 to replace air injection unit and fuel sensor and thermometer so car could pass inspection. I had all the items repaired and engine light still comes on. It has approx 60K miles. The dealer is refusing to repair air injection unit stating it is not under warranty. When I purchased car it came with 100K warranty for drive trane. After taking to certified GM mechanic who fixed everything on list the car still will not pass inspection because the air injection unit continues to take on water. This car is a lemon and GM should not be able to get away with this. I cannot afford to get it repaired therefore, I am subject to get a ticket. I still owe money and cannot trade it in. How much longer are american made car manufacturers going to screw the american people!!!"?" I will never purchase another american made car as long as I live!!! I have not even mentioned the fact that the car loss complete power while I was driving at 60 miles/hour on the trnpk. Everything shut completely down. I could not steer. Fortunately there were no curves and I was able to drive to side of road as the car slowly came to a halt! there must be a law against this!!! what recourse do I (we) have"??"

The vehicle has a severe hesitation when the engine is under a load. This has been called a surge by one mechanic. Had truck 2 months bought it used with 29,000 miles it's a GMC Envoy. While going up hills on the highway at 60 mph, the engines starts to miss/surge/hesitate causing the vehicle to lose speed and RPM's. as you slowly press the gas pedal to gain speed the engine misses more. I had this truck to the dealer 6 times for this problem. They changed the fuel module on the engine then rebuilt the transmission. I was told by them it's the characteristics of the vehicle.

- 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. 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.

I purchased a 2005 GMC Envoy sle in March of 2006. Since I purchased the vehicle it has stalled several times. Once while stopped waiting for traffic to resume and numerous times while driving at a very slow rate of speed. I have taken it to the dealer twice and both times they have said that they can not find what the problem is.

When driving at slow speeds, in the process of slowing down or at a complete stop the truck experiences engine surges. It happens unexpectedly and gives no warning. It's extremely dangerous because I've almost rear-ended people numerous times due to the surges. It was brought into the dealership for service and they said they did a software update but could not duplicate the problem. I'll be making an appointment for another service call within the next week. I thought it was just me but then a co-worker said she had the same issues to the extent that she sold her car back and bought a completely different make & model.

: the contact stated while driving uphill at no particular speed, the engine stalls and operates at a reduced speed. Additionally, the headlights intermittently work at night and the gas gauge provides an incorrect display of the proper fuel level. Although the vehicle was seen by a dealer numerous times, the dealer was unable to duplicate the problem. The consumer stated the electrical system is faulty. The left front window dropped the lights became dim and the battery failed. Updated 04/06/06.

Consumer 2005 GMC Envoy has a defect that can not be repaired. Vehicle stalled. The hazard lights came on when the turn signal was in use. The dealer replaced a bad flasher.

- Rochester, NY, USA

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.
