The back window comes unglued to the convertible top when the car is parked outside in warm weather. Ive seen this in several other mini cooper roadsters within the past few weeks. This causes the car to have a hole in the convertible top and leaves the glass hanging from the sensor. To fix it you need to buy a whole new top. This HAS to be a design defect.
