Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

Percentages are of component mentions. A single complaint can name more than one component, so these do not sum to the total complaint count.

That does not guarantee a specific vehicle is unaffected — recalls are issued against VINs, and new campaigns are announced regularly. Check a VIN on NHTSA.gov.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The suspected failed component is the front differential carrier bearing on my 2021 BMW 750i xDrive. [XXX] BMW of Westmont, Illinois diagnosed carrier bearing damage and oil leaks and recommended replacement of the front differential. The vehicle has approximately 53,791 miles. The failed differential/carrier-bearing assembly is currently available for inspection, subject to the vehicle remaining at the dealership and before the component is replaced or discarded. I have specifically requested that BMW and the dealership retain the failed component if inspection or engineering analysis is necessary. The dealership's repair order is XXX, dated XXX. 2. How was your safety or the safety of others put at risk? The vehicle developed a significant grinding noise during acceleration from a stop. The grinding continues for approximately 5–15 seconds, depending on how long the vehicle is under acceleration, and goes away after the vehicle reaches approximately 30–40 MPH. I am concerned that failure of a major front drivetrain component could result in an unexpected loss or interruption of proper power transfer, particularly during acceleration from a stop or at low speeds. The vehicle also has a documented differential oil leak progressing to a drip. I am concerned that continued loss of differential lubricant could contribute to further mechanical damage or failure. I have therefore limited use of the vehicle while seeking diagnosis and determining the appropriate repair. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The vehicle was inspected by Laurel BMW of Westmont, Illinois, an authorized BMW service center. The dealer documented the customer's complaint as a grinding noise when accelerating from a stop and documented the diagnosis: “Front differential replacement due to carrier bearing ,oil leaks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
