2023 GMC Yukon: problems, recalls and reliability

“Engine seized up on the highway after recall was performed. I nearly avoided a wrecked getting it off the road. I had to wait over 5 hours for gm to tow me then ended up having it towed myself. Now the car is at the dealership with backordered parts, they agreedto pay for the tow now it seems to be an issue that I paid the to trcuk driver cash, & parts have no ship date. Gm customer servive agents are rude & do not seem to ave any sence of care in the world about anything”Owner report · Engine · Sep 2026

“My vehicle was with ANCIRA GMC Boerne for approximately three weeks where they replaced the transmission control system/module, the centralized OnStar module, and diagnosed both rear screens for replacement. Approximately one month after getting it back, at only 49,800 miles, I experienced a complete loss of propulsion. The vehicle shut down while I was driving. Given the recent transmission repair and the fact that this failure occurred while the vehicle was in motion, I no longer have confidence in the safety or reliability of this vehicle. I have young children riding in this vehicle daily and I'm not comfortable accepting another repair and simply being told it's safe to drive.”Owner report · Fuel/Propulsion System · Sep 2026

“The powertrain malfunctioned and it at the dealership for an engine replacement. The vehicle lost propulsion on a 2-lane road while passing another vehicle. It cut off completely and started to decelerate. There was no warning or indication that this would happen and was dangerous in that I was accelerating to pass another vehicle when the event occurred. I was able to safely pull into a driveway, but the vehicle would not crank as it could not detect what gear it should be in. It was towed to a GMC dealership locally who confirmed 2 days later that the engine would have to be replaced. It is under warranty and will take 3-4 weeks.”Owner report · Power Train · Aug 2026
