One problem related to vehicle overheat has been reported for the 2007 Mini Cooper S. The most recently reported issues are listed below.
In 2013 my Mini started to overheat. I had the fluids checked and everything was ok. I drove approx. , 10 miles and the car completely overheated, the oil light came on and the car smoked and almost caught on fire. I had it towed to the dealership (Mini northwest in fife wa,) they said there were no recalls and I needed a new motor and cooling system. I paid 7500$$ for a new engine installed by the Mini dealership in July 2013 at my own expense. On Dec, 23rd 2014 I drove my Mini approx. 12 miles and parked the car in the driveway. The car was not overheating, no warning lights came on, 15 minutes later the car had flames shooting out from the hood. Fire extinguisher would not put out the fire. The car then moved approx. 5 feet forward up against the house and became completely engulfed. The tires blew up the sunroof blew up and then the back window blew out. The car is a complete loss. Mini claims they have never heard of this before, yet there are several articles of the same thing happening to other cars, including a class action suit and recalls.
