GMC Sierra 2500

DOT AH9K82 3425 LT265/70R17 121/118Q All four brand new tires on my brand new truck have bulges on the sides of the tires. The truck feels floaty and unsafe at highway speeds. The car dealership is saying it’s fine, won’t replace them, and says it’s a known issue with the tire.

I recently purchased my vehicle from Big Star Dealership in Baytown Tx. At a little over 1000 miles i was towing a camper. The vehicle stalled, fuel pouring from engine. It was towed and repaired due to fuel pump failure. At a little over 3000 miles the vehicle would not start. Dealership initially said water contamination then changed it and said gasoline contamination and now they say DEF contamination. The vehicle stalling the first time almost caused me to wreck the vehicle

Intermittent trailer disconnect and loss of electric trailer brake output while towing Airstream. The truck is connected to the trailer through the seven Way plug. There are no modifications to the truck. This is a safety hazard as I pull a 9000+ lb trailer. Trailer connection drops momentarily and integrated trailer brake controller loses communication with trailer brakes. I went on a 5000 mile trip and my trailer brakes were connecting in disconnecting consistently. Every time there was a…

The curtain airbags on both the passenger and driver side deployed while driving down the road. The truck is available for inspection although the deployed bags have been cut off in order to drive it home. Pictures were taken before doing so and are available for inspection. My son is pretty shaken up and has injuries to his shoulder, face and his ears are ringing.

GM Duramax L5P diesel engine electrical connector for #4 fuel injector. This failure caused the Diesel exhaust brake, which controls downhill speed, to disengage, extreme shaking of the vehicle, emissions system warning and speed limiting. This occurred while descending a steep grade while towing a 34 feet long, 10,000 pound trailer. This is a known issue with this diesel engine and documented in GM Technical Service Bulletin 23-NA-027. Inspection and repair at a GM dealership confirmed a…

During normal use, the factory wireless phone charging pad in the center console overheated, produced visible smoke inside the cabin, and melted the charging surface area. No liquids or foreign metal objects were present. The phone was placed normally on the charging pad. The incident created a burning smell and visible damage to the interior trim. The system did not shut down before damage occurred. This appears to be a potential electrical or thermal safety failure in the factory-installed…

My 2022 GMC Sierra 2500HD was previously repaired under GM safety recall N232426400 / NHTSA recall 24V060 for the power-unlatching tailgate switch, which can fail from water intrusion. The recall repair was completed and the recall now shows as closed. Recently, the same tailgate switch problem occurred again. The dealer diagnosed water intrusion/corrosion affecting the tailgate release switch circuit, including damage to the related wiring harness/connector. GMC customer assistance stated…

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…

Brand new delivery there was a noise that changes with engine RPM. It also changed with turning the steering wheel. The dealer diagnosed a bad power steering pump. Due to possible metallic contamination all related parts that are connected to the power steering pump including the HydroBoost brake assist are going to be replaced
