I'm filing an urgent safety complaint regarding a series of severe defects in my 2026 Volkswagen Tiguan (VIN: [xxx]) that pose immediate, life-threatening hazards. On xxx, I took delivery of the vehicle, which was refueled by the dealership. By xxx, with temperatures soaring to 104°f, I encountered three critical issues: 1. **engine stall during low-speed turn**: while turning at 2 mph, the engine shut off without warning, losing power steering and brakes, and displaying a message to "manually restart the engine. " 2. **engine stall while reversing**: the engine stalled again while reversing into a parking spot, triggering the same emergency warning. 3. **structural window seal failure**: at 55 mph, the driver-side window seal tore away, becoming a projectile that struck the passenger-side window, creating a severe distraction and road hazard. Despite reporting the engine stalling issues to the dealership, the service manager didn’t open a formal repair order, citing the stalling as "intermittent. " on July 5, while attempting to refuel with half a tank, gasoline violently sprayed from the rear undercarriage, indicating a catastrophic failure of the fuel tank venting system. These incidents within 72 hours of delivery highlight systemic manufacturing and quality control failures. I have had the car towed back to the dealership via flatbed tow and the Volkswagen roadside assistance representative assisted with this transaction. I urge the NHTSA to investigate the fuel tank venting mechanisms, engine management software, and exterior seals of the 2026 Volkswagen Tiguan. Immediate action is necessary to quarantine this VIN ([xxx]) and assess potential safety recalls or stop-sales. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

I was driving in 4 lane town traffic going under 10 mph and the hazard lights came on by themselves, and the car died. Propulsion stopped. Fortunately I was able to pull onto a striped median, and once I was over shock, 3-5 ish minutes, I started the car and drove to the dealership. I don’t remember any warning message, and it seems like the steering and brakes were hard once it was dieing, but I was so shocked it’s hard to remember exactly. This happened in rainy weather, about 65 degrees around [xxx] on [xxx], in bentonville, ar. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
Unknown road hazard was hit by first car and then hit mine which the hazard rolled underneath and gashed my fuel tank.
