NHTSA Complaint #11424772 — 2011 GMC YUKON

I have replaced the battery and alternator. My door locks keep locking and unlocking on the own while driving, all my electrical in my car dim and keep resetting, my gauges are going all over the place. My car will turn itself off. While stopped at a red light, it seems to want to go on its own. While not running, I get in to leave, and my key at times don’t want to turn over. Then at times I try to start it and it will tell me theft control and won’t crank. When I’m out of my vehicle at home, my car will lock itself when the setting is turned off. The problem has been going on for a year but only getting worse now.
