There is a cooling system failure in my car that has caused cylinder head issues and head gasket issues. Even though my car is a 2009, it only has about 53,000 miles. I purchased the car in December 2019 and in January 2020 the car overheated while driving and then I noticed the coolant was leaking from the car. I replaced the hose and thermostat. Now in August/September 2020 the car overheated again and there was also leaking from the coolant. I took the car to the mechanic and they said the engine needs major repair work. I recently noticed recalls on this make and model regarding the engine and engine cooling, however based on my experience with this car, I'm thinking this may still be an issue with this car. Additionally, I reviewed the carfax report from the previous owners and there was no information about any resolved recalls. However, I spoke with the BMW dealership that the car had work done at from the previous owner and they said the recalls in 2012 (auxiliary coolant pump) and 2015 (heat shield turbo charger) were resolved. I also confirmed this with another Mini cooper dealership. Based on the carfax report, these recalls may have never been resolved.

Steering fluid continuously leaks - replace hydraulic hose twice - known defect - Mini refused to fix for free engine cooling - fan runs after shutoff continuously - known defect - Mini refused to fix for free electrical - doors, windows, sunroof fire off on their own while car is moving and when is parked. Will do this at highway speed or when sitting outside (rain or shine) - car unlocks itself and windows all open up -known defect - kind of distracting at highway speed -Mini refused to fix for free. Dealers will not fix these issues unless you make them recall vehicles with multiple small problems ( not just one big problem) - this model has 73 tsbs that dealers charge you to fix even though the problems are known and dangerous issues. In my mind, many small problems can be more dangerous than a few big ones - steering, door locks, cooling - not good. This is an old car but these problems are old too - known tsbs should not be subject to warranty time frames, they are still dangerous after the warranty expires. When these cars are routinely serviced, these known/dangerous issues need to be corrected or the cars should be taken off the road. I used the date of the last incident, not the first one. Thank you.

Earlier in the day I took the car on a day trip to lake tahoe driving a combination of interstate and mountain pass road. 3 hours later, my wife had taken the car to run an errand and came home and parked the car in the garage completely off and locked. 10-15 minutes later we hear the car alarm going off. We opened the door to the garage and saw white smoke coming from the engine compartment. There was high pitched wining also. When I opened up the door the put in neutral, the lights on the instrument panels were all on with no keys in the ignition. Opened the garage and moved the car to the driveway and away from the house. Called the fire department and I used an extinguisher underneath where orange glow was visible. The glow of the flames were toward the back part of the engine compartment and low. Saw no visible flames in the main compartment when the hood was popped open when fire department showed up they used a garden hose to cool engine compartment and suggested to disconnect the battery which I did. I had the car towed to the Mini dealer in reno, nv. Updated 8/8/12 the consumer stated the parts that seemed to have caused and were damaged in the incident were the power steering pump, power steering cooling fan, and electrical harness all in the engine compartment of a 2005 Mini Cooper S. Updated 08/14/2012.

Vehicle fire 5/2/2012. Car parked for 4 hrs. Returned to car & drove it <50 yards for ~2 minutes (moved it from street to parking lot). Turned it off and went in store. Returned ~4 minutes later, noticed smoke/exhaust smell; presumed it was adjacent car. Unlocked car. Car would't start (no lights/electrical at all). I then noticed white smoke coming from hood. Opened hood then noticed flame/fire inside engine compartment. Went in store, got fire extinguisher and put fire out. Invoice was >$3500 from Mini dealer. The dealer's assessment: "verified power steering pump has overheated to the point where it has burned up internally as well as externally (melting all three connectors and the wiring leading to them). Inspected power steering cooling fan and verified cooling fan is seizing up which very likely led to the overheating and eventual failure of the power steering pump. Removed engine compartment fuse box to examine megafuse powering the power steering pump, fuse is intact and did not burn up. Inspected power steering pressure hose and it appears the rubber section of the power steering pressure line was subjected to the heat/melting of the main power connector (it's in very close proximity to the connector) and it appears the hose has taken a level of damage from the heat. Recommend replacement of power steering pump, the wiring section/connector pigtail from the fuse box (this is the main power connector), the engine wiring harness (contains two other electrical connectors to the pump which received extensive damage), the power steering fan (likely cause of failure), power steering pressure line (high pressure hydraulic line which has been exposed to the main connector melting and subsequent heat), and other miscellaneous items associated with those components (o-rings, crush rings, hose clamps ect. . . )".
