2020 BMW M550I Problems

Owner-reported complaints filed with NHTSA, grouped by component

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.

report

From owner reports, verbatim

The front differential and rear drive train has been problematic and has failed in model years starting 2019. My car is a April 2020 car with 34,000 miles and has already failed. There are numerous cars that share the same V8 engine and drive train, has similar front differential failures at very low mileage. BMW USA seems to not car and address the issue after it being brought to their attention.
