NHTSA Complaint #11697539 — 2024 FORD F-350 SD

The vehicle part ML3Z-16500A18-E, or rear panoramic sunroof panel, spontaneously shattered while the vehicle was parked and turned off. I was not driving, and nothing impacted the vehicle. There were no signs of attempted break-in, falling debris, or vandalism, and there was no object inside or around the vehicle that could have caused the breakage. With this being tempered glass, it fragmented violently. This sudden failure created a significant safety hazard, as shattered glass covered the interior. If occupants had been inside, this could have caused serious injury from falling glass. If this unexpected failure occurred while the vehicle was in motion or at speed, it could result in distraction, loss of control, and/or a potential collision. The dealer had inspected the vehicle in person and was unable to determine the reason for the failure. The manufacturer has been contacted, but they do not accept responsibility and have not provided a cause for the failure. The issue has not been reproduced, but spontaneous panoramic sunroof glass failure appears to be a known concern on other Ford models. The vehicle had no warning messages, noises, cracking, leaks, or other symptoms prior to the failure. There were no safety alerts or warnings on the dash. The sunroof glass failed without any prior indication.
