“In the morning the car run fine, but once the engine is warm and I start to run errands it stalls. If I wait about 10min or so... I must speed home or to a safe area to let the engine cool. If I come back in a few hours,the truck will start with no problem. It has been to the shop more often then I remember. Is there anyone having these same issues?”
NHTSA complaint #10586255, filed 2014-05, 83,000 miles“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 drivable height. Has there been this problem with anyone else and is there a recall to fix this problem?”

The engine resumed running at full speed. A few seconds later the engine shut off. I was able to coast long enough to pull off the freeway. But without power steering and brakes this was not an easy task. Once the car stopped I turned off the ignition and put the car in park. I tried to restart the car but nothing happened. …”

The vehicle dramatically lost power and the check engine light came on. I was able to avoid other traffic and pull over on the freeway, I then drove off the freeway on the shoulder and into the nearest GM dealer at maximum speed of approximately 30 MPH. The problem was diagnosed several times resulting in rewiring of the throttle body connector and finally replacement of the throttle body after the third incident of the same issue. …”
