“While driving our 2006 Colorado truck, the engine quit running placing us in danger from the vehicles near us. This has happened three times. We were able to navigate to a safe zone. The engine started and we continued our trip. We are concerned that we may be injured or killed. We are not driving the truck until it is fixed.”

NHTSA complaint #10240684, filed 2008-09, 2,400 miles

“Truck will go into reduced power mode while driving. When it does this it will chime a few times and then drop the speed you are driving at to whatever it wants usually it's 40 to 20 MPH, you cannot go any faster, and there is no warning to this at all, and no pattern as to when it will do this. But it has always done it while I have been driving. This is not the first time that this has happened and luckily no one hit me that was behind me. …”

“Gm passlock system in my 2006 chevy Colorado fails daily leaving me stranded for 10-15 minutes until it resets itself. If engine stalls in a turn lane, it creates a hazardous situation.”

NHTSA complaint #10419998, filed 2011-08, 20,000 miles

“I have a 2006 Colorado 2006 crew cab l-5 engine. I have owned it for 2 1/2 months. It has been to the dealer for 1. Rear main bearing seal leak three times. 2. Two wheel alignments. 3. Auto- transmission cable fell off. This was when I was bringing it in to the dealer for one of the many repairs. 4. It still has to go back for replacing the rear window (on order). This vehicle has been in the shop for 25% of the time I have owned it.”

NHTSA complaint #10152534, filed 2006-03, 1,828 miles

“Engine loses power over 55mph and misfires on cylinder one. Engine light comes on. Dealer refuses to fix after looking at it and saying nothing has completely failed yet. They are waiting for me to be stranded on the side of the road I guess.”
