What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Brake pipe blew out from corrosion... Light front damage to gmc and rear end damage to car in front from lack of braking power.
Fuses, fuel pump and filters, oil, and everything else as recommended. It put me in the ditch. It stranded me in the center of a freeway in winter. When it sits for a while, it resets, only to do it again. T/c light turns on also.
When the traction control engages, a total loss of input to the engine results and the vehicle does not move (it essentially stalls). I was almost struck in an intersection while waiting to make a left turn on a green light in early december of 2011.
I let my freind take vehicle and she said when she braked the pedal went to floor.she was half mile away and made it back .I looked at level in master cylinder and had to put fluid in.noticed brake fluid on the undercarrige which led me to rusted brake line up front.
Just bought car electrical has been acting up for a while now (30 days) and now dash has gone out sunroof wont open pr close and driver side passenger window doesnt work auto store wont fix or take back car
Vehicle went into reduced engine power and stabiltrak warning light came on. Reduced speed from 60 to 10mph. Now occurs on a regular basis.
The contact stated that while driving 1 mph and making a left into a parking lot, the vehicle power steering failed. The vehicle was shifted into neutral and was able to resume to normal. The failure occurred on numerous occasions. The vehicle was not diagnosed or repaired.
Intermittently at hwy and side road speeds, truck will shut down, check engine light comes on and extremely rough idle and loss of engine power occurs. Have followed all recommended fixes but problem persists. Engine code 1516, throttle position sensor out f range +- .05 volts.
