Electronics of varying degrees. Will not recognize thumb drives with mp3 music on it. At times. Sometimes will/sometimes not. Bluetooth phone system has a mine of its own. Several problems too long to go into here. Dealer cannot find a problem says no software issues for this car has been issued. Just use a thumb drive that works. I love this car’s performance, drivability and looks, but without some help from GM this puppy is gonna be gone. Help. The dealer can’t/won’ help.
Selling a car after 1 yr is usually a good way to waste money.
