NHTSA Complaint #11619246 — 2024 BMW X7

BMW replaced the brake system twice to fix the brake failure issues we had on our 2024 BMW X7. When we brought our vehicle in for the 1st brake system replacement in June 2024 at 12,000 miles, the dealership inspected tire tread depth and all tires are in green. When we brought our vehicle in for the 2nd brake system replacement in September 2024 at 15,000 miles, both rear tires tread depth became red, indicating that the rear tires need to be replaced immediately. The rear tires had excessive wear in 3 month or 3,000 miles. We did not let anyone else driving the vehicle. So, the excessive rear tire wear was not caused by driving habits, but by the bad/defect brake system BMW replaced. This bad brake system will affect use and maintenance cost of the vehicle in the future. BMW needs to take the responsibility. The dealership technician also expressed the brake concern causing excessive tire wear issue. BMW denied the replacement of the tires upon the dealership technician requested. We as customers need the help of NHTSA. Thank you very much. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
