NHTSA Complaint #11702451 — 2024 CHEVROLET SILVERADO 2500

Very limited while driving in the dark cause head lights go off and can’t drive in the rain or snow cause wipers turn off not save for my family and I and other drivers on the road Thai all happen, After the dealer (Lithia Chevrolet of Redding, CA) performed GM recall programming on the Serial Data Gateway Module (SDGM) and related software updates, my truck began having serious electrical failures. Immediately after the recall work, all exterior lights, interior lights, and trailer lights began flickering on and off while driving. The windshield wipers also pause or stop for a moment when this happens. None of these issues existed before the recall. This appears to be a module reset or corrupted calibration caused during the recall reprogramming. GM has already told NHTSA that they have hundreds of field complaints about flickering headlamps on 2024 trucks, and they identified lighting flicker as a safety defect. My symptoms match those issues exactly. The dealer refuses to accept responsibility, saying the recall is “closed,” but the electrical failure only began immediately after their programming. This is a safety hazard when driving at night or in the rain, and it affects the trailer braking/lighting circuits as well. I have an active GM case opened for this issue. The truck is unsafe to operate in this condition. I am requesting that NHTSA investigate whether the recall programming is causing electrical module failures and whether additional action is needed.
