NHTSA Complaint #11692403 — 2017 CHEVROLET SILVERADO 1500

When driving all gauges go to zero, truck doesn’t illuminate which gear it’s in, warning lights come on (service 4WD, service stabilitrak, service traction control, reduced power steering, service traction control, service trailer brake system ). When NOT driving if these issues show on the dash when parked and the car doesn’t illuminate which gear it’s in, it does not crank over, does not start, there is no clicking noise either like if it was a bad starter. All the dash lights, gauges, radio goes black as if I turn the vehicle off instead of on. This has been happening since around 2020-2021 in Colorado. It was in a shop for over a month with no resolution. In Idaho in 2022-2024 in a shop for a month with no resolution, and now CA in 2025. No mechanic shop can figure out what is wrong, no “certified GM” shop or “certified GM engineer/technician can tell me what’s wrong. I have had the following replaced already and still having issues. Body Control Module (BCM), the Transfer Case control Module (TCCM), and the Brake Control Module (BCM).
