I was came back from work to have lunch. Car was parked in drive way. After 30 mins of lunch when I came out of the house, I saw smoke coming from the front of the car. Car was not running. Keys were in my pocket. I opened the hood and saw fire in the cooling fan. I pulled my water hose to stop the fire. Waiting for towing truck to come and take it to BMW service. I am surprised to see how a non-running car can catch fire. There is something wrong with Bmws.
Brake lights keep failing due to metal used for connections or computer allowing too much electrical juice to connection. This happens every few months when the metal connection turns black. It now has melted & damaged the tail lite unit and the entire tail lite assembly must be replaced to fix it. The unit is very expensive. I have not replaced it. I have been scraping the black off the metal connector for probably 4 years. Now the mechanic says the entire tail lite assembly needs to be replaced. I have not replaced it. I ask if there was a recall and they said no.
The consumer experienced sudden acceleration. There were random problems when the vehicle was accelerated from stop. The electronic system would fail 3-5 times per week. The problem was unable to be solved.
