The records describe a possible crash, fire, injury, or loss of control.

“The contact owns a 2020 BMW 330i. The contact stated that upon starting the vehicle, the starter made an abnormal, grinding metal-like sound. The vehicle was taken to the dealer, who diagnosed that the starter had failed. The starter was replaced under NHTSA Campaign Number: 26V056000 (Electrical System); however, the vehicle failed to start one morning post-repair. The message "Engine Cannot Start" was displayed. The vehicle was towed back to the dealer, where it was diagnosed that the starter failure had caused damage to the battery. The dealer informed the contact that the battery needed to be replaced prior to the starter replacement. Additionally, the contact was informed that the transmission harness, signal wire, and ending harness had overheated and needed to be replaced. The manufacturer was made aware of the failures, and a case was opened. The failure mileage was approximately 110,897.”

“Good afternoon. I have called and spoken to my local BMW dealership at Grayson BMW service department many times. As of today they report no remedy and have no idea when a resolution will be available. Filing this complaint (second formal written complaint) due to lack of this not being in any sort of "timely manner." This recall is noted as an URGENT FIRE RISK WHEN PARKED for almost seven months now. I have parked the car outside and through the winter and now getting into the summer. In looking up this recall and reading associated documents, it seems there has been a remedy to many makes and models but still nothing for the 2020 330i, and no word on what to do, advisement, or timeline on resolution. I called the NHTSA hotline but after waiting, decided to attempt another written complaint. Previous complaint #11712900. Thank you, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)”
