NHTSA Complaint #11707972 — 2023 GMC YUKON XL

I am writing to formally file a complaint regarding a serious and ongoing issue with my vehicle that has placed my safety at risk and resulted in significant inconvenience and financial burden due to General Motors’ failure to honor my warranty in a timely manner. While driving on the highway, my vehicle suddenly began losing power and displayed flashing warning messages indicating that it would not shift into gear or out of gear and that power could be lost. This created an extremely dangerous driving situation and posed a serious safety risk to me and other motorists. I brought the vehicle in for warranty service, but General Motors was unable to honor the warranty repair in a timely manner. As a result, I was without my vehicle for several months while it sat undrivable on the dealership lot. Once the vehicle was finally repaired and returned to me, the exact same transmission-related incident occurred again. Once again, I was left without the vehicle for an additional period of days. This repeat failure has severely shaken my confidence in the reliability and safety of the vehicle. When I picked up the vehicle after the subsequent repair, I was informed by a General Motors technician that the brakes and rotors were most likely pitted and damaged and would need repair or replacement because the vehicle had been sitting undrivable for such an extended period of time. I was explicitly told this damage was expected due to the prolonged inactivity caused by the unresolved warranty issue. It is critical to stress that the vehicle only sat undrivable for such a long period of time as a direct result of General Motors’ inability to honor the warranty in a timely manner. Despite this, I am now being told that the brake and rotor damage is considered a “maintenance issue,” even though a General Motors technician directly advised me that this damage would occur as a consequence of the vehicle sitting for months due to warranty delay
