One problem related to radiator hose has been reported for the 2003 Mini Cooper S. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2003 Mini Cooper S based on all problems reported for the 2003 Cooper S.
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.
