Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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.”

“Have a 2003 yukon denali and when it hit the 131000 miles mark the fuel gauge stopped working leaving me to tell how much gas I had left using the automatic computer telling you how many miles to empty. Next the oil gauges stopped working. My speedometer quite working leaving me to not knowing the speed I am traveling this quite working while I was driving down a highway. To make matters worse my rpms are starting to go goofy which means that to is going to stop working as well. I was told that having my dash taken off and fixed could run anywhere between 700$ not including labor fees. …”

NHTSA complaint #10735912, filed 2015-07, 217,000 miles

“Reduced engine power/stalility control disengaged message displayed, engine went to idle and would not exceed 5-10 MPH. Traffic from behind served to avoid decelerating vehicle. I understand this is something that is somewhat common with these GM models. The possibility of rear end collisions may be experienced due to rapid deceleration due to loss of power. Happened intermittently again during the day. It clears itself after the vehicle sits for a while but there is no warning when it might happen again. …”
