“Unknown . The safety recall is extremely dangerous and I drive my child around. This is unacceptable and very unavoidable by providing a remedy or give me a new car. This is not my fault and my life and my family’s lives are in danger.”

NHTSA complaint #11698060, filed 2025-11

“The BMW X3 went in for a recall to reprogram the DME. After updating the DME software by BMW the DME was no longer talking to other modules. The BMW Assistant Service Manager said and I quote him IT'S A KNOWN ISSUE WITHOUT A FIX . I ask for clarification and I was told that there were some 100 modules or so that are in the car and that they now no longer reliably talked with other modules as a result of the updating the DME recall software. …”

“The passenger side daylight running light stopped functioning. I called BMW dealership while it was still under warranty and was told that if it was simply a light needing replacement it would be $500. At the next oil change I had a diagnostic test done and was told that the modules for both daylight running lights had overheated and melted and that a headlight also would need replacement. The cost of this was quoted at $4,200. This is a huge safety concern as this could easily cause an electrical fire. …”

“Car spontaneously caught on fire. Total loss. Drove car home from haircut appointment 5 to 10 minutes away. Parked car as normal and went inside. Within approximately 5 minutes loud knock on door “Your car is on fire!” I came out of my home and saw my car in driveway with fire erupting from engine area onto windshield, and through hole in middle of hood. Took a few seconds of video, then ran into house for large fire extinguisher. Emptied fire extinguisher contents into hole of hood and into fire area coming out from engine area onto windshield.”
