2026 Gmc Yukon Complaints

The vehicle was parked and turned off for approximately 45 minutes on a residential street along the curb in front of a house when the rear window suddenly shattered. I was inside a nearby house at the time. A landscaper working in the area reported hearing a single loud pop and then my vehicle’s alarm sounding. He stated he was not close to the vehicle and did not see any object strike it. When I inspected the Yukon, the entire rear window had exploded outward and inward, leaving no glass remaining in place. Glass was scattered both inside the cargo area and outside behind the vehicle. The upper liftgate section had also popped open, which is consistent with the sudden pressure release that occurs during spontaneous tempered‑glass failure. There are no impact marks, dents, or paint damage that would indicate a rock strike or external force. Given the circumstances, the debris pattern, and the absence of an impact point, this appears to be a spontaneous failure of the tempered liftga...

The center screen (infotainment), which shows controls for cabin climate (A/C, heat) and many more functions of the vehicle fails to turn on at random times. It is available for inspection. The external air temperature is in the upper 90s; temperature inside the car’s cabin is easily 115 or higher. This makes safe operation of the car not possible. Additionally passengers cannot occupy the vehicle safely at these extreme temperatures. The problem has been reproduced by dealers. UNKNOWN whether the components have been inspected by the manufacturer. No warning lamps or lights.

Engine failed at 12, 430 miles. Dealer said it required a new engine. This happened on 06/06/2026 and I am still without my very expensive vehicle. There were no wanring lamps or other engine failure notificatioins before this occurred.

**Incident / vehicle info:** - **Year / Make / Model:** 2026 / GMC / Yukon (Elevation) - **Date incident began:** ~mid-March 2026 - **Odometer / mileage:** under 1,000 - **Component:** Back Over Prevention: Rearview Camera (and/or Electrical System / Visibility) - **Crash? Fire? Injuries? Deaths?** No / No / No / No - **Vehicle still owned:** Yes - **Dealer or manufacturer contacted?** Yes — servicing dealer Rick Hendrick City Chevrolet (Charlotte); GM Customer Care cases 101763052 and 102071761 - **Description (paste this — ~1,700 characters, under the ~2,000 limit):** My 2026 GMC Yukon Elevation experiences intermittent total failure of the center infotainment/display screen, beginning around mid-March 2026. The failure is heat-related and intermittent: the screen functions on cool days, and on hot days it fails the vast majority of the time, unpredictably, after the vehicle heat-soaks in the sun. When it fails, the entire screen goes dark and I lose the backup camera and surround-...

So the ultimate failure is from a catastrophically failed crankshaft journal thrust bearing. Which could be caused from one of two things: 1) The crankshaft thrust bearings they are putting in these motors are made with inferior materials, probably cheap Chinese crap or 2) The crankshaft end play tolerance was never set properly, giving the crankshaft the ability to move forward and backward in the engine more than it was designed to. Which will over time beat up on the thrust bearing until it fails. In either case it would result in the same progressive issue showing itself. It will start as a squeak here and there. Which, as the soft thrust bearing material is unable to hold the proper oil film thickness for lubrication, will spiral into more and more heat being sent into the adjacent components, plus the buildup of metal particles being sent through the entire engine oiling system. Which will then start killing connecting rod and crankshaft bearings one by one. If the engine survive...
