My car was brought into the dealership for an oil change and rear brake repair on Tuesday (June 26, 2007). Wednesday evening (June 27, 2007) the car was driven 15 minutes, parked for almost an hour, then driven a mere 30 seconds to change to a different parking spot. Walked away for a minute and noticed smoke coming from the front of the car. Upon opening the bonnet, there was flames coming from the underside of the engine. The first attempt at using a fire extinguisher temporarily put out the fire, then it re-ignited which the fire department was then called to put it out safely. The car was brought the next morning (June 28, 2007) to the dealership and was not looked at until the next day (June 29, 2009). The diagnosis was the steering pump failed, upon which it overheats causing the fire. …
I parked my car in a parking garage after driving approximately 20 miles. I walked to a dentist down the street for an appointment. While at the dentist I get a call that went to my voicemail that my car (while parked with the engine off) was on fire and was filling the parking garage with smoke. Upon receiving the message I rushed home to find that the fire was already out, but the smell of smoke was still very strong. I noticed that the inside indicating lights of the car were on as if the key was in the ignition of the car. I immediately disconnected the battery and inspected the car to find the source of the fire. Upon inspection I found that the flames had come from behind and slightly below the motor. …
While traveling north on us 221 from bent mountain, va to roanoke va my hydralic steering totally failed. As I travelled a short distance my brake light warning lights, ABS light, other brake system light, battery light and air bag warning light came on. I looked at the engine temperature guage and the temp was normal. I pulled into a parking lot, raised the hood, checked the fluids in the engine compartment and reentered the car. While sitting in the drivers seat I heard a loud explosion, looked forward and noted thick steam coming from the engine compartment. I turned the engine off, exited the car and when the steam dissipated I noted that the cooling system filling/overflow tank was split in half damaging a protecting cover on the firewall and sprayed a building wall and window with engine coolant 10 feet away in front of the vehicle. …
Car impacted the rear end of a Jeep at low rate of speed (was braking to avoid crash in the front). Upon impact the car burst into flames. The air bag deployed. Luckily the occupant of the vehicle was able to get out of car. Within minutes the car was totally in flames. No one was killed or seriously injured but if the occupant did not get out when they did the occupant would have died due to smoke or flame injury.my complaint is that this low front end impact should not have resulted in immediate fire and large flames. I have photos of the car just after the occupant got out of the vehicle and also photos of the car after it was towed back to wrecker yard.

Our 2003 Mini Cooper was driven in October 2015 in first and second gear, in bumper to bumper slow traffic, uphill for about a mile. When we shut the car off and got out of it, a fan in the engine compartment continued to run. We went back into the car, started it again, then shut if off for a second time, and the fan continued to run. The fan ran about 5 to 10 minutes while the car was parked. We have been told that the stage 1 cooling fan has failed and that the stage 2 cooling fan was running to cool down the engine.
After driving the car under normal circumstances a short distance and parking the car, a fire ignited in the engine bay. The fire extinguished itself prior to the fire truck arriving. Vehicle was towed to local dealer who, upon inspection, indicated the power steering pump and/or associated hardware had failed and caused the fire.
While driving 10 MPH a fire started in the dashboard. Consumer managed to pull over, and put out the fire out. Then had the vehicle towed. Dealership was notified, but did not resolve the problem.
