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 vehicleâ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 temperedâ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 liftgate glass, likely due to internal stress or a manufacturing defect. I am requesting that the dealership inspect the liftgate assembly, confirm the cause, and consider warranty coverage for the glass replacement and any related components.

GMC YUKON 2026 STRUCTURE:BODY

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 survived to this point, itâs now a ticking time bomb. It is either going to just seize up and not run anymore or the exciting route would be a connecting rod breaks and makes a window sized hole in the side of the engine block.

The contact owns a 2026 GMC Yukon. The contact stated that while driving at 65 MPH the engine seized. All the warning lights illuminated after the failure. The vehicle was towed to the local dealer, where it was diagnosed that an engine replacement was needed. The vehicle was not repaired due to the part being backordered. The manufacturer was not contacted. The failure mileage was approximately 10,000.

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-view cameras, all HVAC/climate controls, audio, navigation, and most secondary controls. Steering, brakes, and engine are unaffected.  This creates two safety hazards. First, loss of the rearview camera image eliminates rear visibility when backing â the exact risk FMVSS 111 is intended to prevent â raising the chance of a backover crash. Second, loss of all climate control in extreme heat endangers occupants in North Carolina summer temperatures, and a blank, unresponsive screen is a driver distraction.
