Insulation crumbling on all wiring inside both headlight (driver and passenger sides) units resulting in malfunctioning headlights, running lights, and marker lights. Unfortunately, a common problem and a huge safety concern. Issue is exacerbated but not caused by heat. Insulation on wiring to navigation, radio/media player, climate control unit, or ccc (car communication computer), crumbling causing malfunctions to occur in all the above sections. I suspect much of the car's wiring to be in similar, poor condition. I have read that many european cars from the '80s, '90s through the first ten or so years of the 21st century used a soy based, biodegradable wire insulation as part of a "green movement". This early implementation of said wire does not last much longer than 10 years, much less than that when exposed to heat.

There are thousands of cars on the road like this. The manufacturers keep producing vehicles with this type of wiring. It's wonderful that the insulation degrades. It's absurd to start biodegrading when the car is just five or so years old.

I ordered new light bulbs to change out my halo angel bulb lights (running parking lamps) .which said they were out on my screen inside of the bmw . When I twisted off the housing cap in the back ,the wiring inside of my headlight housing which turns on my parking lights left and right is totally degraded and flaked off ,the copper cables were touching everywhere .I read this is because germany use biodegradable material but this is a very dangerous fire hazard for driving on the highways and road in florida . We as 5 series owners for these years need a recall of new harness with better wiring .even if you buy a new housing it will do the same thing in 4 years guaranteed . You would have to find some one to rewire it with the same cables ford uses so it can last 20+ years . Please fix.

My 2008 bmw 535i headlight went out and I took it to a certified mechanic to change the headlight bulb, he took out the headlight and shown to me the wiring in both headlights have flaked off and had presented a fire hazard situation which caused the fuse the blew. I researched the bmw forums and found lots of people with the same issue, hence, it is not an outlier. I contacted bmw USA and they refused to remedy the situation. I was told by them that the vehicle is out of warranty and that the vehicle mileage was past the headlight wiring should not go bad in 8 years and they were rude and told me they will not pay for it. I also learnt that most of these headlight wires in the e60 flaked off within 50k miles and are not discovered until a short or blown bulb. Hella (the manufacturer of the headlight) said it is not their problem since the make the headlights to bmw specifications.

Wires inside headlights have insulation crumbling off. Fire risk. So many bmw's have this problem. A clear issue that bmw knows about.

Vehicle was previously driven the day before drove perfect no problems, the day after the vehicle when you put in drive or reverse it would automatically go back to park on it's own and would not move the vehicle was parked in the drive way as normal. I had vehicle towed to bmw they diagnosed as the mechatronic sleeve needed replacing they charged me 1300 dollars my wife picked the car up and drove 50 miles and the car started doing the same previous behavior I contacted bmw they had me to tow back to their dealership a second time both tows cost me 125 dollars each the car was then diagnosed as needing a 9000 transmission and I was told the previous repair that I paid for would not be credited toward the new transmission I'm outraged.

My 2008 bmw 535i is suffering from the same passenger restraint system malfunction error as the earlier bmw models. The federal safety agency information I've read indicates that the passenger airbag will not deploy in the event of a substantial front end collision, which poses a significant risk to passengers. Bmw only recalled model years 2004 - 2006, however. This is not an isolated incident to those years. My 2008 bmw 535i throws the error every time I drive with or without a passenger. Both the passenger side seat belt light and the passenger side airbag light remain illuminated any time the key is in the ignition. What is being done about more recent bmw models?

Driving a 2008 bmw 535i at highway speed, approximately 50 MPH, when, with no warning, large red warning light appears, "engine overheated - turn off engine." light came on suddenly and engine died to 5 MPH and then stopped running. Barely able to get to the side of the road and in great danger from trucks bearing down on a mountainous curving california highway. Discovered the problem was an immediate failure of the electric water pump which causes sudden engine loss placing the driver in grave danger. This problem has been reported by many drivers to bmw (see online forums) and they know this is a serious problem but have not issued recall notices on the electric water pumps on their vehicles. They previously issued recalls on the high pressure fuel pumps but this also requires a recall as the car abruptly dies at highway speed.

Pressing the shift (transmission) selector into the reverse position, causes the shifters electrical ribbon cable to get pinched and the lights in the shifter and sport button fail to work anymore. Repositioning of this ribbon cable or using a different insulation method would solve this problem.
