Example complaints

“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.”
NHTSA complaint #10597490, filed 2014-06, 100,000 miles“Severe electrical problems in vehicle,everything stopped working on it!!!! Vehicle shut down in a middle of a busy intersection, I replaced transmission 2 times as well!!!!had no lights,turning signals,no heat heat then the vehicle just stopped completely nothing just dead!!!

Only had it 2 months and transmission went out pd that then once again electrical problems!!!!!”
NHTSA complaint #11298334, filed 2020-01, 140,000 miles“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.”
NHTSA complaint #10597491, filed 2014-06, 112,000 miles“Over the years I owned this vehicle, I had it serviced numerous 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.”
NHTSA complaint #10585999, filed 2014-05, 73,710 miles“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. …”
