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.

Message on console - " passenger restraint system malfunction ". Took vehicle in for repair; BMW dealership "thinks" it may be a wiring harness electrical short. They evidently need to discuss problem with BMW corporate to figure out to properly diagnose problem and how to repair. My husband and I are very concerned about driving this car even after it may be "so called" repaired. We are concerned that if an accident does occur, and one or more of the airbags do not deploy; there may be serious injury or death to myself, my husband, grandkids, or other passengers.
Engine wiring is made of soy products with attracts rodents to feed and destroy the wiring. When this occurs it puts the driver ad passengers in danger because certain functions such as brake light, headlights and windshield wipers may not work properly. This is becasue when the wiring is compromised , circuits are broken which causes the vehicle's systems connected to that circuit to partially or completely fail, rending a vehicle partially or completely inoperable. The vehicle was inspected the the BMW dealership service center and they confirmed it was rodent damage . Geico insurance also inspected the vehicle. The vehicle started to restrict engine performance and the engine service light came on stating there was a drive tran malfunction.
