I bought a 2008 528i July 2024. Got Emissions & Tag at the end of August. Oct 5 2024. My car was on Fire. Drove the car 11 mins got out for a few mins got bk in crunk the car and a flame shot out of what I'm assuming is a fuse box on the driver side. The car had flames coming from under the steering wheel area in the dash. When we crunk the car we could smell wire burning at first. Then flames..The vehicle has an active recall that clearly says A Pcv heater valve will cause the vehicle to over heat and short circuit causing a fire. Wiring harness needs to be replaced by adding a fuse to keep this from happening. The car was having issues passing the emissions. It was throwing a code something to do with the crankcase positioner something to do with Emissions. The car started running rough and idling rough before the fire happened.I sent bmw pics and the fire report. …
Been smelling burning plastic/or oil thru air vents. as if the pvc valve was melting per recall description on probles, it fits the description, the only thing that happened to the car recently is one of the windows regulator anti trap functions it says antitrap function window disabled, then slowly started noticing burning smell for the first 10 minutes of everyday drive, my safety and many others could be very compromised , as I live on a mobile home community, and these properties have a high risk of fire hazard, and the fumes I am smelling, also I dont wanna get caught in a vehicle fire anywhere, much less on traffic, freeway or cause an accidents because of disabled vehicle, - the list goes on . thanks For allowing me to make a complaint and bring awareness for many other owners

Driver side headlight went out, so I automatically assumed that the bull was blown. Went and bought $100 bull that controls the high beam and the low beams, replace the bulb, and the headlight still doesn't work. Took the ball back and got another bulb, and the headlight still doesn't work. As I was replacing the bulb I noticed bare wires showing, on multiple wires, as far as I could see. This is definitely a safety issue , as it could cause my car to catch fire.
All of the internal headlight wiring insulation on both headlights is crumbling off which is exposing the copper wire, causing sparks and shorting out. I have performed much online research and apparently this is a known problem by BMW. Currently it's a huge safety issue because it's unpredictable when headlights will short out while driving, losing sight of the road and possibly increasing risk of accident.
2008 BMW 528i automatic sedan with 104K miles... Head light wiring harness (driver side and passenger side) insulation is degrading resulting in bulbs malfunctioning/burning out regularly/shorting out/blown fuses, and possibly an electrical fire. An employees at one BMW dealership, said BMW is aware of the issue and refuses to address the issue' until they are forced to by the government or a lawsuit.
Insulation covering headlight wiring cracks off leaving large amounts of bare areas. This resulted in electrical shorts, draining battery, erratic electrical system behavior, blown headlight bulbs, and an intermittent burning smell in my car.
