2026 GMC Sierra 2500 Recalls & Complaints

Incident: June 9, 2026 · Filed: October 26, 2026

My 2026 GMC Sierra AT4 HD intermittently has no power steering assistance when I start the vehicle, making it extremely difficult to steer. This occurs randomly, approximately once every one to two weeks, and has nearly caused me to hit another vehicle on multiple occasions. A few months ago, the dealership inspected the truck, performed a software update, and told me the issue should be resolved. However, the same problem occurred again after that service visit. I contacted the dealership and requested another service appointment and a loaner vehicle because I need transportation to work. I was told there is a waiting list for loaners. GMC customer service has opened a case and is contacting the dealership to help arrange service sooner. The steering issue remains unresolved, and I am concerned it could cause a collision.

Vehicle experienced a complete loss of audio, to include warning chimes, bluetooth audio, radio, and blinker on/off notification warning. This can be a serious issue because without hearing the click notification That your blinker is on, another vehicle may think you are turning and pull out in front of you, possibly causing a serious crash

While driving, the vehicle audio system intermittently loses all sound for approximately 1-2 seconds. During the audio loss, entertainment audio, turn-signal click sounds, and vehicle warning chimes all disappear simultaneously and then return. Vehicle is currently running infotainment software version 662.11. Issue occurs while driving and has happened multiple times. Concern is that loss of warning chimes and turn-signal sounds may reduce driver awareness of safety-related notifications. During complete audio loss (Blinkers, chines, etc), vehicle needs to be shut off for several minutes to recover audio loss.

Aug 14th, 9:49 pm - Vehicle was placed in park and driver got out. A few seconds later the vehicle started moving forward under its own power towards the driver who was now infront of vehicle walking foward away from vehicle. Passenger hopped over the driver seat to press on brake pedal to stop vehicle. At same time, driver turned around and noticed vehicle moving towards him. Passenger was able to stop vehicle but not before it ran off the driveway and into and over a recreational firepit area. Driver was on opposite side of this. Driver got in to vehicle, verified transmission was now fully engaged in Park, and reversed the vehicle off firepit area. Damage to both vehicle, and firepit ring and landscaping area. Security footage later confirmed vehicle was placed in park, brake lights went out, and vehicle remained stationary for approximately 3 to 5 seconds before driver exited vehicle. It was when driver shut door that vehicle then moved, as if the Parking pin did not engage or failed to stay engaged. Owner traded vehicle in with another dealer soon after, due to other ongoing issues involving the steering and brake system that had not been resolved. Approximately 11,580 miles on vehicle at the time of incident. No personal injuries reported.

Ongoing issues with Steering pull to right, and brake pull to hard right when applying brakes, which also turns steering wheel to right upon application. Have to keep steering wheel towards left with constant pressure to go in straight line and when braking. Driver has to be aware of changing road conditions that could affect that. Multiple inspections at multiple dealers have found no obvious issues, and multiple alignments performed, with tires also being replaced have had no success in correcting issue. Front suspension starting to feel loose due, and rear suspension squeak when going over bumps. Also recently found rear axle is shifted slightly to right. Suspect all are related. No parts replaced to date other than the tires. Happens daily. No accidents to date. Daily driver with long trips at times. Steering pull Issue has present since new but everything else has occurred since about 1800 miles and has progressively become worse. Conditions becomes worse at highway/freeway speeds of 65 to 80, but occurs as low as 10mph. Going back to 3rd dealer to look at it again. Truck is 2026 with 10,583 miles.

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

Incident: May 7, 2026 · Filed: May 8, 2026

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 wireless charging system.
