Example complaints

“Abs stability tracking lights come on, car dies no power steering or brakes seems like a safety issue driving a car that is still moving with no steering or brakes. In the past the fuse box under the hood caught on fire and my electric seats would not shut off and burnt out.”
NHTSA complaint #10794556, filed 2015-11, 110,000 miles“Reduced power/traction control light came on suddenly and reduced car power immediately. This made for a very dangerous situation while passing a truck and entering the highway. The car dropped speed very quickly making for a potentially deadly situation. This problem comes and goes with no warning until it happens. Research shows this is a big problem for GM vehicles especially the 2009 Buick lacross models. It's a disaster waiting to happen if it hasn't happened already. This needs to be recalled asap.”
