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. …

I have had continuous issues with the electrical system in the front drivers side headlight with burnt plastic housing to the main headlight and the plug for the blinker system. Sometimes it will work and most of the time it won't. I cant tell you the amount of times it has stopped working in the middle of using the blinker. Every time I attempt to change it out, the bulb ends up still in good shape after looking it over. I have always inserted a new one but the issue remains. I have had to replace the whole headlight unit because of the melted plastic not holding the plug any longer and the issue remains. The passenger side seatbelt light has been on for the past several years and will not go off. It shows a light stating the airbag is off. …
Two years ago, the driver side door would not open from the inside or outside of the car (pulling on both handles didn't open it) and attempting to unlock it by the dash unlock button didn't work. . The only way to exit the car was to crawl across the front of the car and exit out the passenger side. Was told that the problem was caused by a faulty door actuator. Fast forward to today and the same thing is happening again. I can't open my front drivers side door from the inside or outside which is obviously a major safety issue. Pulling on the handle on either side doesn't open the door and using the dash unlock button doesn't help unlock it either. After doing some research on this, it looks like this is a chronic problem with BMW E90 models (mine is a 2008 328i). With this being a major safety issue and is common with this model of vehicle, is there the possibility of a recall?
Due to the CRANKCASE VENTILATION (PCV) VALVE HEATER problem and BMW claiming they have no remedy for it yet, this has caused my engine to overheat smelling like burning electrical, The Container holding reserve antifreeze has broken off plastic components that may somewhere be in the cooling system. The valve cover gasket that was replaced only 3 years ago is beginning to fail and is leaking oil into the brand new spark plugs and coils. This is unacceptable. They say to stop driving the car if you smell burnt electrical. Heck, I have smoke coming from the engine at times. How are people who only have this 1 car suppose to get places when BMW delays repairing people's vehicles. They are wasting our money! They should have to repair all of the parts that this issue has caused damage to while they have us wait for remedy that seems to never come!
