“Reduced engine speed warning light comes on and drops truck to an idle. I feel this is very dangerous in traffic and on highways. My mechanic has not been able to locate problem. All forums and online help has brought me to dead ends. This is my last resort, I believe GM knows what the problem is and am hoping they will do the right thing and recall before someone is seriously hurt or killed from this issue.”
NHTSA complaint #10438674, filed 2011-12, 120,000 miles“This vehicle displayed a message thet the engine was running at reduced power. The vehicle's engine slowed to idle speed while we were driving on a public street. We had been pulling a travle trailer just prior to this happening. This created a possible danger to us as well as other drivers on the street since we could hardly get the vehicle to power up so we could get off the street. I called the local dealer in beaumont, tx. I was told that this was a commom operation to protect the enging from damage and that there is no recall for this problem. …”
NHTSA complaint #10398842, filed 2011-05, 71,511 miles“Had truck for one week, having a good time, and then the car stalled eleven times on me. Wheel locks up and I am traveling at 60 miles per hour. Even stalled on top of the greater new orleans bridge with a truck full of kids. Very scary I am terrified to go anywhere far and am not pleased with the fact I had to pay a hundred deductible to have it repaired. I haven't paid the first note and shelling out money for repairs. I hate this. Then the dealerships treat you as if you are crazy. They claim it was the fuel pump! Now the service crew at (?) thinks I'm crazy, I'm just scared. …”
