Engine Failure Problems of GMC Envoy

Over the years I owned this vehicle, I had it serviced numerious times for engine failure. The last and final time, the dealership (ewing automotive) could not find anything wrong. However, while traveling on the highway at 60 miles an hour with a full tank of gas, I lost all power steering control and the car stopped dead. This was extremely dangerous and led me to take a minimal amount in a sale, just to get rid of this dangerous car. It is very disappointing to learn that gm was fully aware of this deadly issue.

The contact owns a 2002 GMC Envoy. While driving 50-70 mph, the engine failed and the vehicle lost total power. The failure has occurred on four occasions. The vehicle was taken to the dealer from where it was purchased three times, but they could not duplicate the failure. The vehicle was taken to an out of town dealer and has currently been in the shop for four weeks. The manufacturer stated that they could not assist because the failure was not under warranty. The current mileage was 67,000 and failure mileage was 56,000.

While passing another vehicle we lost engine power, no acceleration power, foot had gas pedal all the way to the floor. We were facing a car head on and a ravine on the left. The car we were passing realized there was a problem and we were able to manuver back into the right lane without being hit. We stopped and waited and then tried to restart and was able to have engine power and gas return. I called the dealership and they first told me it must have fixed itself. I was really afraid this would happen again and requested they take the vehicle and run a computer history to see if it stored the code. They confirmed that the throttle body was defective. Dealer replaced. I reviewed your website and see all of the same complaints about stalls, engine failure, no acceleration. I contacted gm and requested they take my vehicle as trade in on 2003 yukon that had 2500 miles but, was comparable to my 2002 Envoy. I would be back in a 5 year note but, I would feel much safer. The gm complaint clerk I was assigned told me there was not anything he could do because my vehicle was repaired and still under warranty. But, he called the dealer and told them he would allow me a $1000. 00 cash voucher to use toward the purchase of a new vehicle. I did not ask for a new vehicle, I was willing to trade for the 2003 but this is a slap in the face. They didn't even want to give me the trade in value on my Envoy. I would have then been upside down in a vehicle loan. This is the worst service and treatment I have ever received. These vehicles are dangerous. . Just look at the complaints for the same problem. We were so close to being killed!! do something! I really hope you will do something to help the consumer before someone does die. (this veh was in the dealer in July and I complained then that I was getting 14mpg in town and 18 on the hwy. They tried to sell me an engine flush. I no longer feel safe in this vehicle.

Engine failure due to manufacturers factory defect to one or two pistons in the engine. Engine was replaced by leith GMC service center on 05/10/02 with a new engine.

Engine failure-car stalls out while driving in traffic for no apparent reason. On 1 occasion, after pulling over to side of road vehicle was able to be restarted, other times it was towed to dealership. Have taken back to dealer 3 times where computer system was changed out but problems are still occuring. Contacted gm hdq in detroit, sent area zone manager who states nothing wrong with vehicle and refuses to buy back vehicle. I fear for my safety as well as my life when driving this vehicle. Have noticed numerous complaints for this same problem, please help to take these dangerous vehicles off the road.
