Car would die intermittently and the traction control light would come on.Ended up needing a crank sensor, what the tell tale sign was for me was the tachometer would fluctuate even when the engine speed was constant.

gear shifter would not click into gear,found that the linkage rod bushing failed which allowed the rod to pop off of the trans linkage. new bushings are available or you can replace the linkage.
faulty window regulator is the cause of the pop noise.
have had several leaks,most recent was the oil cooler O-rings but now I have a leak from the oil pan gasket and rear main seal. Expensive little buggers if you don't work on your own like me.
There are reports of the electric door locks malfunctioning.
There are reports of premature clutch wear on cars equipped with manual transmissions. Clutch replacement on these vehicles can be quite costly.
Minis have an electric power steering pump that is prone to failure. When replacing the pump, our technicians advise inspecting the cooling fan because it is often the cause of the failure of the pump.
Failure of the automatic transmission is common. Even though the automatic transmission is advertised as "sealed for life," our technicians recommend the automatic transmission fluid be replaced every 30,000 miles with only the approved Mini/BMW fluid. Our technicians recommend thorough troubleshooting before replacing the transmission because programming procedures can affect how the transmission shifts and there is a special procedure to refill the transmission.
