Wiper problems of the 2026 GMC Yukon

While operating my 2026 GMC Yukon at4 (VIN [xxx] ) on [xxx] pelahatchie, mississippi, the panoramic moonroof spontaneously shattered at highway speed. No impact, no debris strike, no external cause. The failure produced a violent report and showered tempered glass into the cabin, forcing an emergency stop on the shoulder during heavy commercial truck traffic — a serious secondary-collision risk caused directly by the failure. I spent hours roadside clearing glass and duct-taping the open roof aperture to make the vehicle minimally drivable. Nighttime wind forced an unplanned overnight stay in north alabama before a multi-hundred-mile drive back to washington, DC with the vehicle compromised. In DC, I was forced to park the visibly compromised vehicle in a high-foot-traffic area with work valuables that could not be removed, then drive 20 miles to the dealer in heavy rain the next morning — exposing cabin, electrical systems, child seating positions, and headliner to water intrusion. The shattered glass fell directly above the second-row positions where my [xxx] and [xxx] daughters ride daily. They were not present. Had they been, close-range tempered glass would have created serious risk of injury to face, eyes, and airway, plus driver-distraction crash risk at highway speed. The vehicle is approximately [xxx] weeks old. This is the second manufacturing safety defect in under one month — the first a second-row driver-side captain's chair latch defect, filed separately. Replacement moonroof glass is on national back order until ~June 1, 2026; the vehicle will be out of service over six weeks. Nhtsa's 2017-2021 panoramic sunroof investigation closed without action despite thousands of similar complaints. The pattern continues into the 2026 model year on gm's flagship full-size SUV. I urge NHTSA to track this and similar reports across the 2025-2026 Yukon, tahoe, suburban, and escalade for a defect investigation.

In the 2026 Yukons, almost all physical buttons have been replaced by the giant center touchscreen. When starting my vehicle, about a third of the time the screen will not come on, and can’t be turned back on by any means. It will randomly come back on after a few more trips/restarts. This renders several critical systems inoperable. All hvac does not work, defrosters aren’t available, back up cameras and parking assist is not available, and control of any navigation functions or options (ie heated/cooled seats) are not possible. There are no physical buttons for these items, so there are no other options. Voice commands do not function properly when the screen is black, so no option there. After my third visit to the dealership and an open case with gm, they are finally authorizing a screen replacement. We will see if this fixes it. However, my previous explanations from gm pointed to a nebulous future software release, with no date or detail.
