Owner report 11696961 · 2025-11-01 (November 1, 2025)
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 can cause rear end collisions by braking when no obs…

Owner report 11716907 · 2026-02-10 (February 10, 2026)
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 installed by the dealer in all cases. Despite this, t…

Owner report 11734291 · 2026-04-28 (April 28, 2026)
On 3/14/26, on I-75 in Troy, Michigan at 70mph the vehicle, with 4000k miles on the odometer completely shut off. I pushed to restart the engine and it would not restart. My whole family was in the car and we were on a curve. I was able to coast to a flat shoulder. The vehicle would not restart or shift out of park. OnStar took seven hours to tow the vehicle. The dealer is installing a new L87 6.2L engine. I do not have the vehicle back yet. I received an economy car as a loaner. The dealer says GM will not extend the factory warranty desp…

Owner report 11758602 · 2026-08-21 (August 21, 2026)
9 months into ownership, with 24,000 miles I had complete engine failure pulling into an intersection. Slamming into park while moving and shutting down. This is a known issue with the GM 6.2 liter engines but I specifically waited to order a 2026 as this was far outside the recall window GM had in place for this known issue and was led to believe the issue was fixed going forward. The car was towed to a GM dealer and sat for 39 days for a complete engine replacement. Now, a week after it has been returned it has sputtered and shut off as I am …

Owner report 11741588 · 2026-06-02 (June 2, 2026)
While operating the vehicle, I began to hear a metallic grinding noise originating from the center of the engine compartment. The sound was clearly audible within the cabin. Approximately one mile before the vehicle ultimately failed, the engine began to malfunction. As I slowed to a stoplight, the vehicle started to shake before shutting off abruptly and entering a coasting state. All electrical systems powered down and the vehicle would not restart. Shortly thereafter, heavy smoke began to emit both inside and outside the cabin, visibly comin…
