Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Was driving up a grade and the vehicle failed to downshift to climb the grade properly on the freeway so remained at 60 MPH while in drive. Vehicle also seemed to accelerate under its own power where I had to stop the vehicle by putting it into neutral in order to brake safely almost as if I was braking as the vehicle was accelerating. I was at 55 MPH on a flat service without even touching the accelerator. I did notice higher rpms while in neutral. I did take it to a garage and they could not duplicate the problem and my front brakes needed to be replaced under the circumstances. …”
NHTSA complaint #10965991, filed 2017-03, 130,000 miles“Horn button is part of air bag. The horn button shorts out and the horn blows all the time. Have to remove fuse to stop horn blowing. Had to replace air bag to fix. In a few months the problem reoccurred. Its too expensive to replace air bags so I am left without a horn this is a safety issue. Can the manufacturer provide a fix? The internet shows this is a very common problem for a lot of GM cars.”
