One problem related to vehicle overheat has been reported for the 2011 Mini Cooper S. The most recently reported issues are listed below.
The engine light kept coming on and the fan kept running even after car has been turned off. The gadge would read cold that hot. Took it to mechanic, the mechanic claimed it was a safety mechanism to keep car from over heating, had the car for 4 week and the car just shut off showing the same issue. The thermostat was not correct also. This was city in motion and stationary, once it cooled off it would start fine, but then just cut off, each time it stop I just had it towed which was 3 times rather than driving it , I just did not trust the vehicle.
