 Mechanical issues all the time, 60k and so far have had to replace; The Alternator, Sparkplugs, coils, breaks, roaders, the battery. Also seems to be a big issue with the ABS module on this model. It goes bad and the Start light, Break light, and cruise control go off. To replace it is pretty expensive depending where you take it. So while the car is nice, make sure you only lease a BMW not what I expected when I got it. Not buying another one anytime soon.
