On XXX around 4:15PM, i was driving my 2024 volkswagen Jetta at approximately 65 mph onXXX in [XXX] under normal weather conditions. Without warning there was a loud explosion resembling a gunshot. The panoramic sunroof glass spontaneously shattered and exploded, showering the inside of myself and my car with glass fragments. There was no leading vehicle, overpass, or evidence of road debris or rock failure. The sudden explosion caused immediate driver distraction and created a severe safety hazard. There was no crash, thankfully, and no injury other than minor scratches and earaches due to the sound. Unknown if hearing problems were caused at this point.

While sitting in the passenger seat of the car, the sunroof spontaneously exploded, causing shards of glass to go everywhere and putting my and the driver’s safety at risk while traveling at 70 mph. No one has inspected it yet and there were no warning messages prior to this issue. This happened on July 3rd, 2026 at 2pm.

My 2024 Volkswagen Jetta has about 14,429 miles, driven almost entirely on the highway between two Texas cities, with little city traffic and no mountain driving. The rear brakes are wearing out far faster than normal. At a dealer inspection on June 15, 2026, the rear linings measured 1 mm and 2 mm, nearly gone, while the front linings still measured 10 mm. This is the reverse of normal wear, since the fronts do most of the braking and should wear first. The vehicle is available for inspection. This is not sudden. A prior dealer inspection on July 7, 2025 already showed the rear linings (9 mm) more worn than the fronts (11 mm). Between the two inspections the fronts lost about 1 mm while the rears lost about 7 to 8 mm, so the rears are wearing many times faster than the fronts. Both inspections were done and documented by an authorized Volkswagen dealer. Given the low mileage and highway-only use, this cannot be normal wear. The rears are approaching metal-to-metal at very low mileage, which compromises braking and is unsafe. The pattern points to a mechanical defect, such as a seized rear caliper or a dragging or malfunctioning electronic parking brake that keeps the rear brakes partially applied. Premature rear brake wear is widely reported on this model, and the manufacturer issued a rear brake pad warranty extension for affected vehicles, acknowledging excessive wear and possible workmanship issues. No crash, fire, or injury has occurred. I am reporting this so the defect can be investigated and other owners protected.

The rear service brake assembly—specifically the rear brake pads and rotors—suffered premature wear and catastrophic structural failure. The defective parts are not available for inspection, as they were discarded by Firestone during the emergency repair to restore the vehicle to a safe operating condition. The problem was first confirmed by an authorized manufacturer dealer, Larry H. Miller Volkswagen Tucson. It was subsequently confirmed, documented, and repaired by an independent service center (Firestone). The vehicle and the failing brake components were physically inspected by the manufacturer's authorized dealership service department at Larry H. Miller Volkswagen Tucson prior to the repair. No dashboard warning lamps or error messages illuminated. The symptoms appeared suddenly at approximately 33,200 miles in the form of severe metal-on-metal grinding noises, a vibrating brake pedal, and noticeably reduced stopping power during routine deceleration.

Transmission control module light comes on and the light states safely pull car over and put in park. It’s tried to been fixed multiple times, they are waiting on a software update. I’ll drive the car and have to pull over because the TCM light comes on and can’t drive/ accelerate. The dealership told me to drive the car and deal with it until it gets fixed. The issue first appeared in Nov of 2025 and it’s been a recurring issue since. I can’t take it anywhere without it happening, then i have to get towed.
