There are 2 owner-reported brakes complaints for the 2021 BMW 2 Seriesin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2021 BMW 228I. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the rear brakes. The service brakes warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the rear brake rotors. The contact was also informed that the rear brake pads needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 25,000.
I have a 2021 with 25000 miles and a 2023 with 6000 miles which make noise when in reverse. The dealer has stated the rear brake pads likely need replacement and rotors as well. It seems questionable that two exact models two years apart and 20000 miles apart are encountering the same issue.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
