CHEVROLET Complaints

Transmission failed to engage gear properly after backing up. Grinding sounds heard when vehicle was in drive. Problem has been confirmed and inspected by Chevrolet dealership. Vehicle is available for inspection. Occupants safety was at risk because gears could have locked up during commute causing vehicle to be undriveable, leaving driver and passengers stranded. Blind spot feature is unavailable randomly, which can cause a possible side swipe crash. When radio is playing suddenly switches to bluetooth randomly.

On July 16, 2025, with 4,514 miles on the odometer, the dashboard displayed warning messages for “Service ECS” and “Service Brake Assist,” along with illuminated indicators for BRAKE, ABS, and Traction Control. At 4,598 miles, the master cylinder was replaced. However, after installing a new brake master cylinder, power brake booster, and Electronic Brake Control Module, the brakes failed. As a result, an independent certified dealer had to reinstall all components to address the issue.

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.

Safety was put at risk when the car lost power while they’re celebrating install in the floor of traffic, causing other cars to swerve around and blow horns. The underlying issue with the car was confirmed by independent service center. There was no reason to have your vehicle inspected all by manufacturer , police insurance for others the warning sign once the car installed and attempted to like it was gonna turn off with service ESC and the light stayed on for four hours

My 2025 Chevrolet Tahoe Z71 3.0L LZO Duramax with approx. 3,380 miles experienced a sudden and complete engine failure while towing my camper on the interstate at night, in the rain, while traveling alone 375 miles from home. The vehicle lost power, displayed warnings, and became inoperable, forcing me onto the shoulder in unsafe conditions. The engine has been diagnosed as requiring full replacement due to a defective crank end play / thrust bearing, under Technical Service Bulletin (TSB) 25-NA-307. This is a significant safety concern for a new vehicle and could have caused a crash. GM has multiple documented issues with this model year, and the car has also experienced unresolved infotainment defects, as outlined in TSB #PIT6393F. Requesting NHTSA to investigate a potential safety defect.
