NHTSA complaint #11710568, filed 2026-01“There are 2 issues with this vehicle: #1) The rear window defrost causes an electrical issue that melted the plastic on our rear sliding window. Dealer claims we put something hot against the window but we did not. This appeared after we used the rear defrost. Several other owners have complained about this as well. #2) The vehicle is advertised as having adaptive cruise but it does not have this feature.”

We took it to the dealer and they also do not know what is the issue. We found several other blogs where owners have had the same issue. …”

We purchased the truck because it had these features. Four days later, on a trip out of town, we found that the adaptive cruise control and lane keep assist did not work. We looked online and saw similar GM vehicles with the same buttons, showing how to use the systems, but ours didn’t work. …”
