My vehicle engine cooling fan caught fire one evening while following behind someone to make sure they made it to a parking lot safely due to their own vehicle having problems requiring them to stay under around 20mph. Once we made it to a parking lot, i exited my vehicle to check on the other person, and realized there was smoke starting to come out from under my hood. My husband waited for me to pull the hood release and then proceeded to lift the hood, only to discover my car was on fire, and it was coming directly from the cooling fan. After almost a minute we were able to put the fire out, and discovered the whole electrical area for the fan was melted and destroyed. There was never any type of warning light or any information at all that would have told me a problem was imminent. Im thankful it wasn;t myself alone or with my kids just driving down the highway because it would have taken over the whole vehicle before i would have known it was having any issues at all. The part is still on the vehicle, which has become inoperable and now any attempts to check the vehicle out have realized that another issues with BMW's is also causing problems with my vehicle. It appears an actual recall was never issued for my actual VIN, rather a collection of years and makes. Any further information or remedy that might get me the ability to actually use my vehicle again would be greatly appreciated. I can also include photos and witness statements if needed,. Thank you for your time.
