2026 GMC YUKON XL

I am submitting this complaint to report a safety defect involving a 2026 GMC Yukon XL AT4 equipped with the GM Brembo brake upgrade. The vehicle is sold as equipped with a full-size spare tire; however, the spare tire/wheel supplied cannot be mounted due to interference from the brake calipers. This incompatibility was discovered only after a flat tire event on [XXX], during which the vehicle could not be safely returned to service. The Brembo brake upgrade is a GM-designed option that is ins

On [XXX], I was driving on the highway with my family in the vehicle and the check engine light came on, then it started running roughly. I headed off the highway on an exit ramp and the engine died about halfway down the ramp. It wouldn't restart after that. This happened about an hour away from my house in Painesville, OH. I live in Erie, PA. I had to tow it to the nearest GMC dealer. They've since concluded that the engine failed and have ordered a replacement engine from GMC. The yuko

This issue affects all vehicles in the GMC lineup. The forward collision alert system is so sensitive that it gives false positives constantly which causes 2 major safety issues with the vehicle. First is that it brakes without warning and when completely unnecessary. The 2nd is that vehicles like mine with a heads up display, have the entire display flash a very bright yellow blocking the field of vision to the front of the vehicle. The system is not able to be disengaged permanently and ca
