The recall 25V-636 remains unresolved after more than 6 month passed since the manufacturer issued the campaign regarding the engine starter. I would like to see the NHTSA to put the manufacturer on notice that this is unacceptable. We cannot park the vehicle outside of structures permanently as this devalues the vehicle and creates a loss of use.

SERVICE BRAKES — Filed 11/09/2025

In November 2025 my breaks quit working. I had AAA haul my car to a repair shop. They ran the codes on the car and found that it was related to a recall on 2021 BMW 540i's for the oil vacuum pump assembly, pan and gasket. I then had it towed to BMW and found out that my vin was not in the recall. BMW quoted me $4587 to repair this on a car with 45,000 miles. I then had it towed to a repair shop that replaced the oil vacuum pump assembly, oil pan, gasket and bolts for about $3700. I think that my vin should have been included in the recall. It was a obviously a common problem with my model and I should not have to pay this much on a car with 45,000 miles. I also had to pay $283.81 for BMW to diagnose it.

UNKNOWN OR OTHER — Filed 01/10/2026

Good afternoon, I am writing regarding the recall affecting my BMW 2021 530i, VIN [XXX] . While I understand the importance of safety recalls, this issue has had a direct and measurable impact on the market value of my vehicle. Due to the recall, I have received reduced trade-in and resale offers, with dealers explicitly citing the recall as a reason for depreciation. This loss in value persists regardless of whether the recall remedy has been completed. I am therefore requesting compensation ($6000) for the depreciation caused by this recall, or financial adjustment or trade in. Please open a case on my behalf and advise on the next steps. I would appreciate this matter being reviewed by a regional case manager if necessary. Thank you for your attention. I look forward to your response. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
