So many annoying things.. BMW, when will you learn
 I am driving the 2015 model. The more I drive it the less I like it. As many professional reviewers have noted, the engine sounds really unpleasant. The shifter can be infuriating esp. changing between forward and reverse is very slow and requires the driver to engage the brake pedal for a significant amount of time. The navigation system is laughable (in the age of Google Maps). Sometimes I still use it but don't put your car in reverse after you entered your destination. The backup camera will come on and wipe out your destination entry. As for the backup camera: horrible contrast and low light performance (where does BMW even buy such low quality components). One of the most annoying things is that you cannot lock the car when you park it in Neutral (hard to believe but true). You have to turn the engine back on and put it in Drive, then get back out and lock it. If you leave it in Neutral it will sit unlocked, completely drain its battery and go dead in a matter of hours.
