Example complaints

“Don't understand why 2002 trucks were not included in this recall, I had the same problem with crank sensor and engine stalling at highway speeds. I had the senor replaced 3 years ago. The national highway traffic safety administration (NHTSA) is directing the recall of 11,974 2001-model-year heavy duty pickups built by general motors to fix faulty crankshaft position sensors, under NHTSA campaign id number 07v521000.”
NHTSA complaint #10312694, filed 2010-02, 60,000 miles“Vehicle stalls out at any speed and will not restart for several minutes. It is random and does this intermittently and is gradually getting more frequent. Based on our research, we understand that the NHTSA is/was aware of this problem. We will be having the crankshaft sensor replaced. This is a serious safety issue for the driver and for anyone traveling behind the vehicle when it loses power.”
NHTSA complaint #10236712, filed 2008-08, 89,000 miles“My 2002 Chevrolet avalanche has stalled on me several times and on a number of occasions in heavy traffic. This is a serious safety concern that I need help with. The local Chevrolet dealer says they are not aware of any problem that would cause this.”
NHTSA complaint #10180674, filed 2007-01, 80,000 miles“On several occasions while driving at highway speeds (60-70) the engine has stalled and left me drifting with no power on the interstate. After drifting off the highway with no power assist steering or brakes to stop and letting it sit and turn the key off and put the vehicle transmission in park the engine will start back up in a few minutes. Sometimes however it may take several minutes for a restart to occur. I can not be certain, but I believe this to be temperature related. …”
NHTSA complaint #10179005, filed 2007-01, 81,000 miles“My 2002 chevy AVALANCHE 2500 has the problem of the engine dying as I am driving down the road at freeway speeds and any other speed for that matter. When the problem occurs, I loose power steering and braking ability.”
