One problem related to radiator has been reported for the 2006 Mini Cooper S Convertible. The most recently reported issues are listed below.
On 2/16/2013 my harmonic balancer went out while driving on the freeway their are no warning lights . What happens is a loud pop then a bunch of crunching noises from that shock your car will go from 55 mph to 20 mph in a matter of seconds . . . Extreamly scary when you see a semi behind you . Mini paid for this malfunction because they know this issue is a major flaw and will cause an accident or possibly someone's death . On 8/29/2013 my transmission failed at 55,123 . . . No warnings just slow lunching and grinding also during this event I found out my engine and transmission mounts were cracked. Seat belts are constantly curling backwards and don't lay flat . Convertible roof drip seal rubber has been replaced more than twice making me believe that Mini has used a sub standard rubber therefore using it in their engine parts . . . Please note that I've had numerous hoses replaced due to being brittle and sub standard . . . Power steering ,radiator,and other hoses . Mini copper is currently battling a class action law suit why do I know about every other car company benign sued ? does it really take a death,accident ,or other issue to make car companies accountable ? please note current mileage is at 68,000 meaning I don't trust this car nor do I feel safe in selling it to some high schooler or other person because this manufacture isn't honest and rushed out a product all in the name of profit .
