2009 GMC Sierra electrical issue?

Asked by Nov 09, 2017 at 01:33 PM about the 2009 GMC Sierra 1500

Question type: Maintenance & Repair

I have a 2009 GMC Sierra. While driving the locks will randomly lock and unlock, the gauges will jump all over the place, the warning lights on the dash will come on and off, and when accelerating from a stop it will stutter and have trouble going. It seems to happen most often when starting from a stop or when hitting the brakes but it also happens at random other times. I am assuming it is an electrical issue but i am not sure where to begin on finding the culprit. Any suggestions would be greatly appreciated. thank you

Maybe a bad ECU or BCM.
