“I bought my 2006 Mini Cooper S Convertible for $9,393 in november 2016 . When driving it home from the dealership I heard some noise, so I stopped at a foreign auto service and was told the clutch and transmission was going out. I called the dealership, but they refused to help, so I had them replaced at a transmission repair shop for $2,500 . Then had a brake job for $394 and spent over $1,000 at a Mini dealership . And then put the car in storage for 5 months. …”

“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 ...extremely 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. …”
