Driving at approximately 10-15 miles an hour entering a parking lot when I noticed flames coming out of the hood scoop of my 2005 Mini Cooper S. After brief inspection from my mechanic, it is believed to have been caused by the wiring harness for ABS or possibly the power steering unit since the fire originated from the rear/right hand side of the engine and those two components. I have a claim opened with USAA but during simple research, I have found tens, if not close to a hundred issues with similar...

characteristics. I know I am not the first R53 Mini Cooper (2002-2006 run) with this problem and this should be considered a hazard and public safety issue. I have included the link to many of the cases captured by the North American Motoring Association (a primarily North American Mini car association) which details 24 pages of these issues. https://www.northamericanmotoring.com/forums/stock-problems-issues/73527-spontaneous-engine-bay-fires.html?ispreloading=1

When adjusting the driver and passenger seats, the airbag light illuminated. After researching online, I conducted troubleshooting. I verified that the wiring harnesses and connectors for the airbag sensors under both seats had come loose, and certain wires de-pinned. The car was running, and parked when this occurred.

the water hose & I were able to put the fire out, we were lucky that I didn't walk inside the house like I always do, it could have been a horrible tragedy for me, my family and even our neighbors. The next day I had the car towed to my mechanic who after an inspection found out if was the power steering pump that got on fire and damaged all the wires around it, since he is a mini specialist he told us about a recall for that specific part, but to our disappointment he ran our vin # and found that our car is excluded from that recall since its a late 2005 production. That exactly same thing happend to us with the actuators, one day while my wife was shopping with my kids, they just got locked inside the vehicle with the windows rolled up, it was a summer day and luckily she was able to get out through the back trunk, we contacted mini because there is also a recall for the actuators and they also excluded our car saying that it was a late 2005 production and were not able to get the recall. The way we see it mini is not taking responsibility for their defective components, it is not fair since I have no way to find out if my car was build with not defective parts, obviously it was. I am terrified by the idea this could have been worst since we r always driving with our kids. U need to do something about this & make mini liable for these safety issues.

After an hours drive, I was standing outside of the vehicle talking w/ the car off. All of sudden smoke starts pouring out from under the hood. I quickly opened the hood to hear some type of electrical fan/pump sound & smoke coming from the bottom/rear side of the motor. I was able to pull the battery terminal & the noise/smoke stopped. I then searched online & found the known issues of the electrical assisted power steering. I found the fuse for the circuit, a 100 amp fuse hidden on the bottom side of the fuse box that had not popped even though the pump was burning itself up. I had enough tools w/ me to pull the fuse, get the car started & make my way home w/o the power steering assist.

Parked at shopping mall and not running for at least 30 minutes, come out to mini cooper on fire. Smoke coming out of engine area, high pitch fan whirling, electrical smell. Power steering failed, shorted out, and caught on fire. Vehicle was not even on and parked when this happened. Appears to be a major failure many others owning a mini cooper have experienced. Bmw/mini cooper of usa did nothing for us and put it all on our and my insurances shoulders. Amazed so many cases of this same issue have happened...

The door would not open, the windows would not go down, the sun roof would not open, the fob would not work, at that point I was locked in my car. I had to kick out the window to get out of my car. When I did get out, I re entered the car and opened the hood and jiggled the battery connection. I shut the hood...

Sudden failure of power steering resulting in very high steering effort, traced by dealer to a well-known failure mode in electrohydraulic power steering pump. Pump and associated fan were replaced by dealer under special ("secret") warranty coverage, due to common incidence of this failure. Existence of this special warranty was found only after search and location of many identical failures on the internet. The vehicle battery was found to be completely discharged upon arrival at dealership. Once a shop...

battery was connected, the pump was found to be running continuously even though the vehicle ignition was in the full off position. Also, the alternator was found to have failed, presumably because of excessive stress imposed by the defective pump on the vehicle electrical system. Cost of alternator replacement was not covered by the manufacturer. This known failure mode is believed to be a significant safety defect. Formal recall of affected vehicles by nhtsa is warranted, since sudden loss of power steering at speed can result in loss of vehicle directional control. *Js

After I turned my car off, a noise like a fan kept running. It drained the battery causing me to get my car jumped. Then power steering went out, and when I arrived home after struggling to turn vehicle and operate safely, the fan did it again, after 5 minutes battery was dead. This is a major issue with this year of mini I have found after researching tonight, and I am very displeased to see that canada has recalled this issue and the usa has not! People could get seriously injured. There is no rhyme or reason as...

In september 2012 I noticed a loud fan noise that wouldn't turn off. The car was also overheating. I noticed that it was very hard to steer the car, but I thought that was due to the overheating. Mechanic determined failed cylinder head gasket in 11/2012. The radiator was replaced and the thermostat was replaced. In 11/2012 the water pump was also replaced. In 12/2012 the battery had to be replaced. In 06/2013 the heater core was replaced. I believe that these issues are directly related to the loss of...

Unfortunately I was blocking a lane of traffic until I could force my way of the roadway. The second incident happened as I was turning into my own driveway.

reverse and tail lights will fail at random. The engine light stays on and the codes read emissions failure. When I talk to mini cooper customer relations they gave me an extended 100,000 mile warranty on the power steering and emissions. Mini cooper claims they can't do the safety repairs due to a part shortage. They extended my already extended warranty to 150,000 miles and are wanting to charge me for diagnostics on these extended warranty issues. They will not offer any resolution and claim it is my problem as a consumer and claim the power steering issues are not safety related. When I asked about the electrical lighting issues they replied with that's not mini coopers problem. *Tr

Occupant seat sensor failure in passenger seat, airbag light comes on and stops airbag operation. I see that nhtsa has contacted bmw for this problem and for this model year; however, bmw/mini won't take blame for airbag failure. Bmw takes irresponsible attitude that even though car has only 36,000 miles, safety is my problem, not thiers. As a side note, dealer says part is $1200 plus installation and reprogramming. Bmw, the ultimate driving (and killing) machine. *Tr

2005 Mini cooper. While driving approximately 45 mph, the front passenger air bag off indicator illuminated with an occupant positioned in the seat. In addition, the failure would occur even when an occupant was not present in the front seat. The illumination no longer continued when the engine was turned off. The vehicle was taken to an authorized dealer, who stated the passenger seat mat sensor would need to be replaced. The vehicle had not been repaired. The manufacturer was notified of the problem. The approximate failure mileage was 35,000. *Tr

Diagnosed by mini cooper dealership as "cracked seat occupancy sensor" inside the seat. Not repairable only replaceable. Airbag will not go off if passenger in the seat.

I have a holes in my car seat and the two vest that I place on the seat. It appears the heated seat had a electrical failure. Took car to mini dealer. They said it real odd this happen. They also nice to say I would have to paid to fix it. Look at many site on internet and seen bmw/mini and other company have issues with heated seats. It do not seem to odd to me. I did not even had the heated seat on because no one was seating there. *Tr
