 - Infotainment System went out frequently while driving- SOS button malfunctioning frequently- Entire dash going out and coming back on while drivingTrunk randomly opening when parked or before driving off (if you are fast enough to get in and lock doors, etc., it won't open.BMW was made aware of the problems but refused to do a Trade Assist Program on this faulty vehicle because of high mileage (29,000), amount still owed (only 12 months of payments) and repair attention not an emergency.Wife had same vehicle (except coupe) we bought one day apart, and they took it back (only constant brake problems and water leaks in the trunk (at 15,000 miles).I recommend steering clear of BMW, but if you still insist, stay away from 2014 640i Xdrive Gran Coupe.
