NHTSA Complaint #11525863 — 2020 BMW X3

The rear differential bolt is a known failure point on these cars. I see it time and time again where there is a clunk noise coming from the rear of the car and sure enough, the bolt has broken on the rear differential and leaves the car undriveable. BMW has said that they are unable to do anything without NHTSA informing them of the issue. There needs to be a recall or active service bulletin to address this issue. This failure is not a matter of “if”, it is a matter of “when”. There needs to be a stronger bolt in place otherwise it is a near $5000 repair to replace the rear differential if not covered under warranty.
