On dec.2 my 2004 bmw 525i was sitting outside my house when it cought on fire at the fuse panel in the trunk on the right fender well. The car had been driven over 100 miles that day. My step-daughter had gotten home at midnight and parked the car. She said the car was fine when she got home at 3;30 am my neighbor knocked on my door to tell me the car was on fire. The fire department was called to put it out as ever time we would get the fire out it would spark and start again. They reported that it was a mechanical problem that caused the fire.

What 2004 BMW 525I owners say
Most recent owner complaints, unedited.
Tl* the contact owned a 2004 bmw 525i. While the vehicle was parked in the garage, a neighbor noticed that the vehicle was on fire. The fire department was called and extinguished the fire. The fire department stated that the fire was due to a faulty battery cable. The contact stated that the vehicle was destroyed in the fire. The contact received medical attention due to smoke inhalation. The manufacturer was not notified of the failure. The contact called an unknown local bmw dealer, but they were unable to assist. The failure mileage was 160,000.
Micro power module (mpm) started smoking while driving, causing erratic engine RPM, and causing smoke inside cabin and burnt electronics smell. Complete loss of radio and idrive functionality. Module is located in trunk under the spare tire. Notified bmw of north america, and they just said that the car was out of warranty and nothing could be done. I feel that this is a serious defect that could possibly start a fire. Several bmw online forums have discussed this issue. Others have remedied the problem by relocating the module to a higher place in the trunk. Most of who own these cars do not know that these vehicles have this vulnerability. Vehicle was moving in the early morning when this happened.
Passenger restraint system warning appears each time we get into the vehicle and start the ignition. Airbag deployment red icon constantly illuminated on the dashboard. The air conditioning system is not working properly. The car does not cool or get cold until the car is in motion. We had a mechanic who we purchased the car from 3 years ago to diagnose the problem but it still continues to not cool properly.

Passenger restraint system light on,effecting airbag,belt tensioner or belt force limiter. Called bmw was told VIN number not in recall how can that be recall is for 2004 bmw. Cost is over 1000. Car was stationary.
I really need some assistance. My seat caught on fire while I was driving. The seat heater keeps turning on and occasionally won't go off I've driven the car maybe 35 minutes tops since the seat caught fire 3 weeks ago. Bmw north america has tried to assist me, unfortunately the dealers are either booked solid or are capable of fixing this technical a problem. They've agreed to fix everything for free & provide me with a loaner car until the issues are totally resolved bmw does not want my vehicle to catch fire again. I was told not to drive it unfortunately none of the dealership consider a car fire top priority. There is a huge likelihood it could continue burning without immediate repairs. I wish bmw north america would assist me like they said. I've had 8 bmw's and never have I had an issue . That is why I've bought bmw's because as long as I did all the scheduled maintenance (a side from this one) my vehicles have been not only reliable but a pleasure to own. I've had very few issues with my current e60 until 3 weeks ago. Since then my life has been chaotic borrowing vehicles renting vehicles and relying on others because bmw doesn't prioritize car fires. I need someone to help me otherwise I will have no choice but to continue driving a vehicle that is a danger to myself as well as my minor child and any other vehicle around me if it were to become fully engulfed in flames. Please call me at your earliest convenience so I can be safe . My contact info is [xxx] [xxx] [xxx] email [xxx] call me day or night I'll be ready to get the vehicle to the proper facility for repair. I have contacted all dealership in new hampshire . Tulley bmw said that the repair was beyond their expertise. I spoke to an absolutely clueless gentleman name [xxx] at tulley bmw nashua *dl information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
Literally a couple weeks ago my drivers side seat caught on fire burning a very deep hole through to the front of the seat and burning a hole in my jacked then burning my skin. Immediately I notified bmw who was extremely accommodating even helping me schedule a repair appointment.. Then the dealership closest to me called me and told me they didn't do recalls and they couldn't assist me. After bmw north america authorized this. I had an extra vehicle until last week when my daughter brought our bmw x3 to college with her. They highly suggested we not use the vehicle until its repaired the seat heater keeps intermittently going off and won't turn off and then it starts burning . I've been afraid of driving it because of the frightening burning smell. I wouldn't be writing u if I wasn't between a rock and a hard place by bmw . Now I'm without transpo and I have a child with epilepsy who I need adequate reliable transportation for. It difficult being told yes by bmw north america then the dealer won't accommodate you unless you consider replacing your vehicle with a new bmw! I am very upset and disappointed with w
I was driving on my way to work and started smelling something burning. All electrical warning lights started lighting up the dash and then displays go blank. Passenger compartment was filling up with smoke coming from under glove box. I pulled over and called fire department. We disconnected battery and took to bmw. They said micro-processor located in spare tire storage area had shorted out due to water. I don't carry coolers and don't leave my trunk open when it rains. How did water get there. Bulletins show that sunroof drains get clogged and water gets into trunk and shorts out electrical. Service bulletin says if this happens, customer pay but move electrical to where it can't get wet. So bmw knows it's a problem and can cause a fire but doesn't care to cover repair. Now I'm stuck with $1000 repair for micro-processor just to be able to tell what else is burned up. I have to pay before I will know if it will cost an additional $5,000 to repair. I'm lucky electrical didn't catch fire and burn up entire car.
