I was on my way to work and had driven only 4 1/2 miles at 6:55am on Thursday, August 15, 2019. I was about 1/2 from work on a city street when smoke began coming out the air vents and steering column. A smell of plastic, electrical filled the car and I pulled into the nearest place when the smoke was quickly increasing. My son and I jumped out of the car and called 911. The fire department arrived almost immediately, and upon pulling up, before they could get out of the truck, the driver's side curtain airbag exploded, the firemen heard the explosion. By the time they pulled their hoses and lifted the hood, smoke was heavily coming from the car. When the airbag exploded, a large piece of plastic shrapnel was blown to the passenger side of the car and stuck between the windshield and the window and stuck into the edge windshield frame. The firefighters tried for several minutes to get the source under control and finally was able to when they disconnected the battery. I had my car towed to BMW columbus, they "repaired the recall" and said that the fire was not a result of the recall. I believe that if the firefighters did not respond as quickly as they did because they were nearby, then my car would have gone up in flames.

Because of poor quality of fiber optics wiring used on the headlight they tend dry rot resulting in a burnt out headlight. Which can become a safety hazard.

My BMW appears to the have an issue with the passenger air bag sensor, but the VIN isn't include in the recall list. Kindly request recall, as the vehicle hasn't been in an accident, but passenger air bag light remains on.

Navigation display reboots constantly. Works periodically. This display gives me access to all of the cars features including warnings and malfunctions with the vehicle. If the display works when the car is on it may not work if you turn off the card and turn it back on.

My BMW was parked outside a restaurant in overland park, ks, at lunch time on March 7, 2017. Auto was locked and all windows and skylight were closed. When I returned to my car after lunch, the car was unlocked and all windows and skylight were open. The key was in my purse and was untouched. Possible theft attempt?

Main headlight failure during night driving cause by electrical short circuit, due to headlight internal electrical wiring insulation failure. Internal electrical wiring insulation seems not to meet sae, nec, asme, etc. Codes and standard for the uses, like engine electrical wiring, subject to heat exposure from headlight bulb generation. Major safety issues can result from sudden headlight failure without previous notice, which can cause accident at dark roads. Headlight failure occurs while driving in a dark road at night.

While I was driving on a street road my stirring wheel got stuck and I lost control of my car swerved into other lane and nearly caused an accident. I pushed the wheel back hard and bought my car on the side of the road. A mechanic found that nearly two inches of water had accumulated in the trunk of my car, the water damage caused electrical failure making the car to become inoperable. By shoddy construction. The modules, are installed in the spare tire well and insufficiently protected from moisture, making them especially prone to water damage that can be caused through the normal and ordinary use of the vehicle. My life was put in danger because of this shoddy construction by BMW. When I notified them, they denied and refused to pay or fix. They literally put my life as well as other drivers life in danger, because my car swerved uncontrollably.

A message on the vehicle display screen indicated that the right-side low beam headlight was malfunctioning. I removed the headlight assembly to replace the bulb and found the wiring insulation is crumbling to the touch, resulting in a short circuit. The headlight bulb is not actually burned out. There are many complaints about this on the BMW forums but BMW and the headlight manufacturer, hella, refuses to acknowledge the problem or do anything about it.

Since 2011, I have needed to have my, 2006 BMW 530xi, vehicle serviced. Serviced for trunk leakage, battery cable replacement, sunroof/moonroof non-drainage issues and passenger airbag sensor issues. I have paid perhaps three - to five thousand dollars for alleged repairs. None of those repairs were permanent and the issues continued on/off until 5/10/14. On that day/date I drove the car several hours shopping and preparing for mother's day. When I stopped the engine in my driveway the car shut off but I could not remove the key fob from the ignition. There was no power throughout the vehicle, e.g. no dash lighting, no internal lighting, no alarm light flashing and no ability to lock doors or open the trunk. Neither BMW-N.a. nor dealership accept any responsibility for the water leakage or other repair issues, even though some manufacturer recalls were announced to the public for these issues, those were said to me to be only for specified VIN numbered vehicles and not mine. I would like to participate in a class action against BMW for these issues and I have saved all my repair receipts to validate my vehicle problems.

  • 21,869 miles
On Feb. 21, 2011 the electrical system showed a massive malfunction warning on my 2006 BMW 530xi. The car computer instructed me to discontinue driving immediately and bring my car to the closest dealer. I brought the car to the dealer. It was determined the sunroof cassette was faulty and water from recent rains leaked through the sunroof (in closed position) ran down drain lines into my battery compartment. Water caused major damage of electrical system, modules, battery etc. BMW told me the repairs, including a needed sunroof cassette would total $23000. BMW admitted the sunroof cassette was faulty, but said I was out of warranty and it would be my responsibility to repair. I did research and found 3 internal service bulletins from BMW, si B 61 13 06, si B 54 02 08 and si B54 04 09 which addressed this issue while my car was under warranty- these service bulletins were not performed on my car. I also have seen many, many of this same issue on BMW message boards. This could have been a very dangerous situation, and I feel BMW should be responsible for this repair. Please help.
