“I was driving my yukon 2003 denali and the error message showed up reduced engine power . I wasn't able to get the speed up to 30 MPH on the highway. I pulled into a parking lot and had someone come pick me up. When I went to pick up my vehicle, the message no longer appeared and it functioned at normal speeds. I am nervous about traveling with my family in the vehicle now.”
NHTSA complaint #10432820, filed 2011-10, 175,981 miles“When driving at low speeds (less than 10 miles per hour) or starting from a stop, the traction control will automatically engage when the gas pedal is applied. 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 was stopped in the middle of the intersection waiting to turn left. …”
NHTSA complaint #10441727, filed 2011-12, 68,650 miles“Driving to work and reduce engine power came on. Engine stalled out and would not gain speed. I was in a lot of traffic when this happen and my vehicle cause a incident because of the sudden engine reduced all speed. Gmc should do some research about this problem and inform the public of all the dangers these vehicles are causing for public transportation. This is ludicrous that Gmc does not have these vehicle off he streets and destroyed knowing that they are putting people lives in danger. I will never ever buy a Gmc vehicle again.”
NHTSA complaint #10543184, filed 2013-09, 181,000 miles“Vehicle powers down without any pattern, rhyme or reason. It will do it at 5 MPH, and at 55 MPH, when driven a lot, and when not. Reduced engine power light turns on, vehicle suddenly slows to 25 MPH max, steering becomes hard, brakes too. Then will totally shut off immediately. I have replaced the battery, throttle body assembly and wiring harness twice. 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. …”
