The vehicle is subject to an urgent safety recall (NHTSA Recall 25V636 – engine starter fire risk when parked). BMW has confirmed that there is no available remedy and no estimated timeline for repair. Due to the open recall and fire risk warning, the vehicle has been restricted from commercial use and removed from a car-sharing platform, resulting in loss of use. BMW has stated that there is no approved interim repair, workaround, or guaranteed loaner or rental assistance. The recall remains open despite the stated risk of fire when the vehicle is parked, creating an ongoing safety concern and consumer impact.

Re: 25V-636 We received a recall notice for the above notice over a month ago. No further communication has been sent from BMW in the status of new part availability and they refuse to assist with accommodations because of the scale of the recall. The letter clearly states that there is a fire risk and to not park near structures. This leaves almost everybody who owns affected cars with no option but to put themselves or someone else at risk of this car catching on fire - where else can you park a car that might catch on fire? Its been 4 months since this recall has been issued nationally and no communicated resolution or targetted timing for resolution. Im concerned this recall will potentially start a gigantic car fire and harm someone, their homes, or their neighbors' property. I find it completely unacceptable that there's not even clear resolution timing for this problem which is essentially a ticking time bomb. People with these cars need help beyond what we're able to do as individuals. Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

I started my vicheal up and turned the heater on on my 330i 2020i bmw I sat there for about 15 mins and noticed a smoke smell I stepped out my car and realized my car was on fire! No sensors went off saying car had any issues regarding coolant or engine oil or anything so I have zero idea what started my car fire Police and fire rescue was there Fire investigation is making a report an insurance representative will be inspecting From what I see online bmw was been having issues with 3 series randomly catching fire either by faulty water pump? By a short circuit? The vicheal is completely totaled my safety was at risk if I wouldve started driving and didn't notice it would've been way wrose than what happened unsure where insurance will be taking the vicheal to

Both the UPPER and LOWER active grille shutters for most BMW models in the 5 model years prior to mine had extended service warranties due to frequent failures of the part. It appears that the design was not improved with my model year and yet my vehicle is NOT part of the extended warranty. My vehicle is only 4 years old and BOTH the upper and lower air flap control motors have failed. The motors are not sold individually, but are sold as a part of the entire shutter assembly which has a part cost of $250 - $350 each with comparable installation costs. The lower shutter assembly requires the removal of the entire bumper. Why is the extended service warranty not applicable to newer models?
