A useful visit to this page takes five minutes. YearTell does not score years and cannot see the vehicle in front of you.

  1. Look up the VIN for open recalls at nhtsa.gov. This year has 7 campaigns on file below.
  2. Electrical. Have a shop scan for stored codes and check battery, charging and any warning lights that stay on.
  3. Engine. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise.
  4. Automatic braking / collision warning. Ask whether the warning lights stay off and whether related recalls were done.
  5. Skim a few owner reports below for Electrical. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.

I am submitting a claim pertaining to NHTSA Recall Number 25V636000 which pertains to a engine starter issue that can result in fire. This recall was reported first on September 23, 2025 and has been gone without a remedy. Since as of today, it has been 212 days without a solution that I am driving a car that may catch fire. This is too long and I am seeking remediation in the form of a replacement vehicle.

I phoned BMW today for an update on this recall. After 6 months, Manufacturer still does not have a fix or repair for your recall 25V636000 and no solution date. This is completely unacceptable.

In September of 2025, I was notified twice by BMW via mail that my car is under recall. The NHTSA Recall Number is 25V636000. It is possible for water to contact and enter the engine starter. This could lead to corrosion which could cause a short circuit and ultimately a fire. They told me it would be fixed free of charge and I would be notified when the remedy was available. There were no such warnings or messages of the problem prior to being notified of this potential failure. Their mailed instructions told me to park the car outside which I did. My car was exposed to storms and hickory nuts from trees fell on my car causing damage. The extent of the damage was classified as the equivalent of "hail damage" and I had to pay $2000 out of pocket to a Paintless Dent Repair shop to get the damage fixed. I called multiple dealerships back in October and they told me to check in February of 2026. It is now March and a remedy is still not available. I called multiple dealerships today, March 16th 2026, and they have all told me that parts are still not available. This is infuriating. I had to pay a significant amount of money due to a defect on BMW's part. I now park my car in my garage where it belongs. It is infeasible for myself and many others to park a vehicle outside. My safety is put at risk every day and I worry constantly that my vehicle will spontaneously combusts and burns my house down. BMW must make this right. I am seeking a timely resolution to this recall as well as a reimbursement for the cosmetic damage I was forced to repair.
