My 2025 GMC Sierra 2500 experienced repeated electrical failures that caused complete battery drainage and multiple overnight noâstart conditions within the first year of ownership. These failures occurred in extreme desert heat, where temperatures in [XXX] reach 120°F. A vehicle that repeatedly fails to start in these conditions creates a serious safety hazard, including risk of heatârelated medical emergencies if stranded. The defect persisted despite multiple repair attempts and two battery replacements. The dealership ultimately told me I would âneed to replace batteries as needed,â instead of diagnosing the underlying electrical issue. Detailed Description of the Problem…

My 2025 Sierra 2500HD repeatedly displays âTrailer Brakes DisabledâService Requiredâ with a lithium- and solar-equipped trailer. The truck passes the EL-52641 simulator, but the failure occurs intermittently while towing and resets after Park or reconnecting the trailer. This closely matches the higher-trailer-battery-voltage/backfeed condition described in N232414840. Please open a TAC case and determine whether my 2025 has the revised Trailer Brake Power Module or whether GM engineering authorizes module replacement.

Normal driving 40mph brake failure and power steering loss. Towed vehicle to dealership
Jun 17, 2026Steering
Power steering pump failed when decelerating after 9500 miles. When power steering pump fails, power assisted braking also fails. Upon deceleration, I could not turn the steering wheel at all or stop the vehicle without extreme pressure on the brake pedal. I narrowly avoided impact with a concrete barricade at the entrance to a parking lot. GM issued a technical bulletin (DCS7112) on January 16, 2025 identifying the problem and failure and directing dealerships to replace the pump on inventory vehicles. No mention was made to repair or notify owners of the potential problem.

Reverse lamps are not bright. Camera does not brighten area either. Very unsafe to reverse in the dark. Have to touch the brake pedal to be able to see while backing. Also have tried the LEDs in the mirrors while backing- although the LEDs are bright- lights to see while backing are insufficient on the stop lamps.
