Found large oily mark under parked car. Turns out to be the thermostat hose leaking due to cracks because of being made of plastic. This is a known design issue by Mini/BMW that could cause an engine to overheat producing a file or blowing the engine. This should come under a recall. Checking online, you can see that it was such an issue last year, that dealers were not even able to get parts for weeks due to the number of failures. Calling the dealer, they readily admit it is a huge problem and they have to replace lots of them. Of course, it is $600 a pop for the fix. Due to the large cost and admitted design flaw, these should all be placed under a recall before someone is badly hurt. Also anyone that has had to have this fixed should be reimbursed for that expense.

My 2007 Mini Cooper S thermostat housing has started leaking to the point that it would cause the engine to overheat at prolonged stops in traffic if fluid is not put in the overflow tank. I have been reading various threads regarding this issue and see that there are several reports of this failure, however Mini does not seem too worried about this part.
