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.

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.

1. The engine starter motor (specifically the pinion starter) has failed, and the auxiliary battery is also showing reduced capacity (only a portion of its 660 cold cranking amps). The vehicle is currently at a service center where the technician has diagnosed these issues. The components should be available for inspection upon request, as they have not yet been replaced. 2. The failure of the starter motor and battery primarily affects the vehicle's ability to start. While this could potentially strand you in an unsafe location, the information provided does not indicate any specific safety incident or risk that occurred during operation. No direct safety hazard has been reported. 3. Yes, a technician has diagnosed the problem and confirmed a fault code in the drivetrain related to the failed starter motor. The technician also identified the auxiliary battery's reduced output. This confirmation comes from a service center, which could be a dealer or independent shop. 4. The only inspection mentioned is by the technician at the service center. There is no indication that the manufacturer, police, insurance representatives, or others have inspected the vehicle or components. 5. Yes. Prior to the failure, when starting the car in the early morning, a "drive train service" message appeared on the display, advising you to visit a service center as soon as possible. This warning was the first symptom of the problem before the starter ultimately failed and the battery drained. This aligns with the technician's diagnosis of a drivetrain fault code related to the starter motor.

While driving approximately 70 mph on the highway, my vehicle’s sunroof suddenly and violently shattered without any warning. There was no impact from debris, no vehicle in front of me throwing objects, and no prior damage to the glass. The explosion was extremely loud, resembling a gunshot. The sunroof glass appeared to burst outward and then collapse inward, sending broken glass downward. Thankfully, my vehicle has a canvas sunshade beneath the sunroof, which was closed at the time. The sunshade prevented glass from falling directly onto me and my passenger. Without the shade, we likely would have sustained injuries from falling and flying glass. There were no road hazards, weather anomalies, or external impacts that could have caused this failure. The failure appears to be spontaneous. This incident created a significant safety hazard due to: The sudden loud explosion at highway speed The potential for serious injury from falling glass The risk of loss of vehicle control due to distraction or injury The possibility of future occurrences in similar vehicles I believe this may be a manufacturing defect involving the tempered glass panel.

I bought my car in 2023 with 12,000 miles. I currently have 43,000 on it. I don’t drive it hard and have always had the maintenance done. I had my rear brakes replaced today at BMW and I was told my engine mounts have failed and need to be fixed asap. Was given a quote of 3000.00. My warranty expired literally 2 months ago. I’m told it’s dangerous to drive but how does this happen? Everything I read says they should be lasting 60,000-100,000 miles at least.

The front axle support and the right front control arm bearing bracket may be separating, which is causing my vehicle to continually fall out of alignment. This ongoing issue is leading to accelerated tire wear, despite the fact that I have not driven many miles. The manufacturer needs to address the underlying cause, as the dealership continues to recommend alignments without resolving the root problem. I have already paid for two alignments, yet the vehicle consistently goes out of alignment again.

I just became aware from Consumer Reports about an upcoming recall on BMWs because of a potential fire hazard with the engine starter relays. I own a 2021 BMW 330i which is one of the models listed. I entered my VIN on the NHTSA and BMW websites and both sites indicated my vehicle has no open recalls. According to NHTSA, BMW will start notifying owners on November 14 about the recall. In the Consumer Reports article and several other articles I read about the recall, owners are being directed to park their vehicles outside and away from buildings and other vehicles. Owners are expected to wait until November 14 to see if their specific vehicle is included in the recall. This is not acceptable! NHTSA needs to hold BMW and other manufacturers accountable for informing owners of a recall in a timely manner; a month and a half delay in notification is unacceptable. Owners need to know if their specific vehicle is one of the ones being recalled. I understand the potential delay in scheduling the repairs because of a shortage of parts. However, there should not be a delay in informing owners about the recall status of their specific vehicles. Please escalate this to whomever is involved in the decision making process at NHTSA.

No entity at BMW, not the dealership, not the sales, not BMW Financial Services or BMW of North America LLC could provide any information regarding the original tires or provide any warranty information regarding the tires - this impact mileage efficiency, miles per gallon and is a way to game the systems. BMW front sensors on act erratically sometimes working and sometimes going off without anything present, during rain/snow sensors would constantly go off for no reason.

In Buford GA at the corner of Elm Tree Terrace and Buford Dam road, I was waiting for the light to turn on a decline. It is important to note that the car was driving in all-electric mode on a full charge. Once the light turned green I stepped on the accelerator to go and the car stalled. I believe the transmission slipped. The gears caught at high torque and jolted the car involuntarily forward. I didn't notice it at first but after a couple of sleepless nights with shoulder pain: I got an MRI and was found to have a torn rotator cuff. It is difficult to associate the injury as it is hard to access the force applied to the jolt. The only word I can use to describe the force of the jolt was violent. I believe there is a safety issue when a high torque electric motor is being run through a slipping or failing transmission and I suspect as a result I have suffered a injury as a result.
