“I was driving a car with family and all of a sudden we all started smelling a burning smell but we thought it must be from outside. However, in just few seconds the vents started throwing vapors so I stopped the car hoping it may stop if some minor damage. However, the hood started throwing oranges color fumes and by the time we all left the vehicle the entire front hood/engine area started burning. There were no indications of any faults in the car. …”
NHTSA complaint #11447812, filed 2022-01“The IP cluster (gauges that display speedometer, fuel levels and other ADAS features) was blanking intermittently, BMW service center suggested software update as they believed it to be a software bug. Later, when the software update did not work, they suggested we replace the battery even though we tested it months ago and it was fine. After the battery replacement when the IP cluster was still inoperable, BMW recommended i pay another $3k for the IP replacement. I am seeing Hyundai have a similar issue but they have shared a proper recall and repair notice to consumers at NO COST. …”
NHTSA complaint #11754501, filed 2026-08“Dear NHTSA Vehicle Safety Hotline Team, I am writing to formally report a serious safety concern regarding my 2021 BMW X7. My vehicle is exhibiting a dangerous condition where it fails to start on the initial attempt, displays a Repeat Start Attempt warning message on the dashboard, and then heavily strains to turn over on the second attempt.While I am aware that BMW issued a safety recall (NHTSA Campaign Number 24V-576) regarding starter motor overheating and engine fire risks for certain 2019–2021 models, I believe the current remediation or scope may not fully protect consumers from the…”
NHTSA complaint #11745413, filed 2026-06“Under FMVSS 101, if a screen experiences a momentary black screen or reset cycle while driving, it is considered non-compliant because the driver loses immediate access to the speedometer, safety and ADAS functions of the vehicle. The OEM (BMW North America) does not acknowledge this issue in their vehicles and ignores repairs violating NHTSA standards.”
NHTSA complaint #11758150, filed 2026-08“The entire car shut down while on the highway with no prior notifications on/from the system. The entire safety of myself and family was put at risk because there where several cars behind us on the highway that could have hit us. I am not sure the dealer has been able to reproduce the issue - Unknown. There was no warning lamps, messages or symptoms of the problem prior to the failure or the car shutting off on the highway.”
