Asked by Guru9JJM68 May 20, 2023 at 11:08 AM about the 2017 Chevrolet Silverado 1500 LTZ Crew Cab 4WD
Question type: Maintenance & Repair
My truck, while driving, locks and unlocks. Engine running or not, sitting in the
garage, my lights will come on out of the blue. Or all of my windows are down
when I walk out to my truck after work. Help, please.

My first suspects would be a faulty key fob and a bad BCM (Body Control Module), in that order. With the key fob, if you keep it in your pocket and have other stuff in your pocket the buttons on the fob may be getting pushed as you're walking, bending over, etc. I used to have that problem with my Grand Marquis. I'd come out from work and sometimes the trunk would be popped or the doors would be unlocked. The body control module is my second suspect because it controls everything you've mentioned. Hope that helps! Jim
RF interference, key fob going bad, BCM programming issues.
