My 2013 BMW 535i (VIN [redacted] ) caught fire spontaneously while parked, turned off, and unoccupied on 11/18/2025 in Westbury, NY. A passerby saw smoke and called 911. Nassau County Police and the Westbury Fire Department responded. Firefighters informed me at the scene that the fire was mechanical in origin. The vehicle was completely off and had been parked for about 20 minutes. I was not in or near the car. The fire originated under the hood. This matches known fire patterns in BMW 5-series models from this generation involving electrical/engine components, even though my VIN shows no open recalls. The previous owner did not register the car, so any recall notices may not have reached them. The vehicle is a total loss.
Heard a clicking noise behind the steering wheel for a few days then I'll the sudden the horn stopped working and all the controls on the steering wheel stopped working. I'm a mechanic so I took apart the clock spring stealing wheel compartment to find all of the wire broken and very very brittle. Cause for concern due to airbag malfunction and is no longer connected properly!!!I've been hearing a clicking noise behind the steering wheel for a few days. Then, suddenly, the horn stopped working, and all the controls on the steering wheel stopped working as well. Since I'm a mechanic, I disassembled the clock spring and the steering wheel compartment to find that all the wires were broken and extremely brittle. This is concerning because it could cause an airbag malfunction, and the wires are no longer connected properly.
