I own [XXX] BMW vehicle affected by a safety recall for a defective engine starter relay that may corrode, overheat, and cause a fire. The recall notice dated November 2025 states the vehicle is not safe to drive, with no remedy available, rendering it unusable and hazardous. Recall N0.25V-636. Under Kansas Lemon Law (K.S.A. 50-645 et seq.), I am entitled to a refund or replacement for this substantial defect impairing use, value, and safety, which BMW cannot repair. I demanded a full buyback at original purchase price, including fees, taxes, and incidental costs, or a comparable replacement. I requested a response within 10 business days. I sent this demand in November 2025 and have heard nothing since. The statute of limitations for lemon law claims in Kansas is four years from defect discovery, per UCC provisions for warranty breaches. If unresolved, I want to pursue legal action for breach of warranty, lemon law violations, and negligence, seeking damages, fees, and costs. Please investigate BMW's handling of this recall and failure to respond. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The Oil filter housing on my BMW 330i failed randomly while driving causing my vehicle to be depleted off coolant within seconds. If you want to inspect the part you will have to reach out to bmw of Columbus for documentation and I can provide the service records for repair. This caused my vehicle to have to be brought to an immediate halt to not cause overheating or engine destroying failure at a time where service/repair isn’t available. There were no warning lights or leaks prior to the vehicle malfunctioning all at once. I ubered to get coolant and once filling the reservoir the coolant immediately leaked out resulting in me needing a tow to the dealership. This problem has been reproduced with many dealers as there’s numerous of report of this online and I believe the dealer has inspected this part but is refusing to replace or recall this part under any type of program or create any type of solution to make this not happen again. There wasn’t any small leaks or warning lights shown before this issue spawned all at once then showing the low coolant light.

While driving, my 2020 BMW 330i suddenly entered “drivetrain limited power” mode, severely restricting acceleration and overall performance. Upon diagnostic review, the cause was found to be a failure of the Heat Management Module (HMM). This created a hazardous situation as the vehicle unexpectedly lost power while merging into highway traffic. Researching online, I’ve discovered numerous reports from other BMW owners experiencing the exact same failure on this model and other recent 3-series vehicles. This component failure is both common and costly, and yet there has been no recall or formal action from BMW to address it. Worse, the HMM is not covered under third-party powertrain warranties because it is considered an electronic part, leaving many owners with unsafe vehicles and no support. Given how widespread this issue appears to be — and the serious safety risk posed by sudden engine power loss — I urge the NHTSA to investigate this component for a potential recall or required manufacturer remedy.

Failed Component: Driver Side (Left) Exterior Mirror Available for Inspection: Yes Safety Risk: The mirror does not stay securely unfolded, requiring manual adjustment while driving, which creates a major distraction and increases the risk of an accident. If not manually secured, it shifts unpredictably due to wind resistance at city speeds, creating a dangerous blind spot that makes lane changes and merging hazardous. Glass isn't adjustable with buttons.The heating function is non-operational, which may impact visibility in cold/wet conditions. Problem Reproducibility: The issue is persistent. Dealer or Independent Confirmation: The problem has not been diagnosed by a dealer, but has been check for DTC and there are no faults. Multiple reset attempts have been performed, including iDrive reset, manual folding/unfolding, and a BMW battery reset procedure, CLS was allowed to shut down fully, with no resolution Inspection by Manufacturer, Police, or Insurance: No Warning Lamps or Symptoms Prior to Failure: None. The mirror was working perfectly before it failed suddenly with no warning signs, noises, or gradual malfunction. No known fault codes prior to the issue. Additional Details: The mirror does not respond to electronic adjustments and must be manually repositioned. The glass will not adjust either unless by hand. When fully open or fully folded manually, makes a loud, forceful clunk and becomes slightly harder to move, but can still be adjusted moved with some effort. It opens far past the normal open position. In any other position other than fully extended or fully closed, it moves freely due to any external forces such as wind force while driving or lightly pushing it. The passenger-side mirror functions normally, including folding, heating, and glass adjustment. No OBD error codes, warning lights, or system messages have appeared related to the failure. Mirror has not had any physical damage or abuse in any manner.
