Bad Transmission
 I bought this vehicle to be both fun and utility vehicle. The transmission behaves so erratically it is downright dangerous. On more than several occasions its lack of response has cause near fatal accidents. It typically hesitates between 2-3 gear which is where you are at when entering a turn-about or merging into traffic quickly. The sports drive mode down shifts so hard that you swear you have been "rear-ended" by another driver. BMWNA has tried to pass this off as part of the "adaptive" or learning features of this car.
