I own a BMW 645ci 2005 convertible I have issues yes isssues with this vechile, first issue is the infamous idrive that never really worked properly since I purchased the car, it blinks on and off for 30mins then it would magically come on until one day it just didn't come back on this was after a trip to the dealer to get the convertible top lock reprogrammed. . So the car was included in the lawsuit so I takes it to the dealer for the reprogramming and my car came out worst then it went in the idrive never worked to this day which is 04/16/2018, my top only opens with the passenger side door slightly opened yes the door has to be open for the top to operate. . . This is what the dealer told me so I was so confused of what the reprogramming was for ? I need answers and it's nothing I did as a owner I was very to the book when it came to opening my top and operating the idrive and etc. . . The infamous coolant leak also comes from a defective bimmer pipe that was installed by the makers of the vehicle and we the customers has to pay to repair these issue that occur on 60% if not more of these cars . . .
Convertible top warning came on saying it was not locked, could not use the windows or anything.
