NHTSA complaint #11656000

Owner complaint summary

The vehicle brakes stopped working on the highway moving at 75 MPH. It felt like the brakes were locked mechanically after all the vehicle electronic fault codes appeared in the dash. The incident occurred [XXX] traveling down a highway right after a vehicle battery charge at a charging station. While driving, all error lights came on, including turtle mode, high voltage battery pack fault, front collision warning failure, failure in all 4 motors, failure of ABS and traction control, and most importantly failure in brake. Tried pulsating the brake, pressing as hard as possible on the brake pedal, but the brakes would not activate. The pedal was mechanically locked like when you try to turn a steering wheel without a key - that kind of lock. We pulled to the emergency lane and let the vehicle coast to a stop. We did a soft vehicle reset and then a hard vehicle reset. It continued locked. After about 5 minutes, all the error lights went out and vehicle worked again. Drove it home and called Rivian, who had the vehicle towed to their repair facility. While this is the first time the brakes failed, it was not the first time all the error lights came on after a battery charge at a charging station. The first time it happened, i took it to Rivian and they said it was a software glitch and gave it back to me without any repair. If a software glitch can cause your brakes to lock up at highway speeds, this needs to be addressed. This has happened 3 times since December of 2024. I also have a video that i can’t upload, but can provide through email. I can’t trust this vehicle with my life anymore. The vehicle has been in service over 12 times with suspension components replaced multiple times, vehicle error faults that can’t be traced to an issue, and now brake failure. This needs to be thoroughly investigated or someone can get killed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
