The contact owns a 2004 GMC Envoy. The contact stated while driving at various speeds, the vehicle would independently accelerate without warning. The vehicle was taken to a local dealer where it was not diagnosed but continued to experience the failure. The manufacturer was informed of the failure and informed the contact that they were unable to assist. The failure mileage was approximately 135,000.

This suv made a loud sound, began to drift, in the rear, at hwy speeds before it tipped over and began to roll, ejecting my two minor sons from the passenger cab before it eventually landed on its side. the roof was molded in a triangular shape, preventing it from resting on the roof as it tilted back onto inside and remains after the last roll The triangular shape was created in the metal after the stabilizing structures gave way almost immediately providing possibly no protection to the patrons inside the carrier cab of suv. demonstrating its inability protect its occupants.

The initial time (3/14) it occurred, I was out of town with my family, embarrassed to say the least. However, mainly uncomfortable, tired, and frustrated because my 87 years old dad was stranded for hours as well as my 66 years old sister who is recovering from cancer. This problem was a serious problem because of our location. We had gone to get dinner and ice cream after getting ice cream we back in the vehicle for it would not start. I called 911 no police ever showed nor would even stop to assist. After 2 1/2...

I was driving down the road when the car shut down everything I was scared because I had traffic right behind me going 45mph and then they car would not run again. I was right in the middle of an inter section at hall road and 59 it was the scariest thing that has happened to me. I bought this vehicle as a used auto and I'm not sure if the emmission system ever got changed and this happened once before and the dealer said not to drive with my house keys attached. I had to get the auto towed home.

Vehicle was stationary and in drive when it had a uncontrolled acceleration resulting in a collision with a garage where it was being parked. Extensive damage resulted to the home and vehicle. No injuries.

The dash cluster does not work correctly, all the lights turn on and doors lock while I am driving on in town or on the highway , all the gauges come on at once while driving on the streets at random times.. The rear has airbags in the suspension and and aren't working properly, I took it to the shop and they said it had 30 codes on the diagnostic machine but they couldn't find the problem

My envoy's cruise control will not engage at any speed above 60 mph. When the cruise control button is pressed the cruise control light will come on and go off again, without engaging the cruise control setting. However, at anything 55 and under the cruise control will engage fine. Also my 4x4 will not work either.

This is a very unsafe vehicle. I purchased it for my husband and have seldom drove until recently when he was injured driving it. He drove through our garage and demolished it. I how drive it and find the brake and gas pedals the worst problem. No matter what shoes or boots you are wearing you cannot control the vehicle. It has cost us thousands in damage and repairs. I do not have pictures, but will obtain them and forward them. The car was just pulling up to be parked outside by out garage when the problem...

Speedometer flucuates past 120 and sometimes drops past 0 while driving. The fuel gauge will show full even when it's not.

I was stopped at a light when the car accelerated on its own, I pressed the brake but the car would not stop . I hit car the car in front of me, I had to put car in neutral to stop the car. Car was towed to dealer, the cause was a internally shorted throttle body. The throttle body was replaced. This was the third time car accelerated on own and would not stop. The first two times my mechanic could not find any problem.

The vehicle will abruptly go from 70 mph to 30's (semi-trailer closing in fast) and I can't do a thing about it!! Service stabilitrack has been a thorn while under warranty and persists to be a problem now that it is out of warranty! From early on, <10,000 miles and over 10 times since, this vehicle had been in to two different dealers and the problem, though intermittent, still exists and is a huge danger to me and my kids but I can't just go buy another car or trade this in like some people (including the car...

After driving vehicle tends to lunge forward even after brakes are stepped on or after parked at a red light, in the first case driving at highway speeds, the speedometer freezes and hangs, during this occurrence we do not know what speed limit we are going which is scary and a safety concern especially with children in the car, to troubleshoot the problem and bring speedometer down to zero mph, the car would need to be turned on and off numerous times to set back to zero

While driving my 2005 gmc envoy my speedometer will stop working and register as 0 mph even when I am moving. It also has shown me travelling at a much higher speed at times. There are many issues with this that I've found while searching the web. It is unnerving and dangerous to not know the speed you are traveling. I have started to use a gps system when I drive to show my speed.

THE CRUISE CONTROL IS INTERMITTENT. *TR
