1. I'd have to say my biggest gripe is with the enough-already! seatbelt chime. I wear my seatbelt when driving, of course, but there are so many situations where a seatbelt just isn't neccessary. Driving up the driveway after getting out for the mail, and driving around the building at work to unlock a series of gates are two daily events for me that don't really warrant the seatbelt.
2. The two-quick-presses-of the-keyfob trick to silence the alarm when locking the car. Sometimes it works. And sometimes it doesn't work. Still trying to figure that one out.
3. Wish the car would stay in Sport-mode between drives. It should stay in whatever mode I want until I press the Sport button again, just like the radio stays on whatever station I last selected.
All minor gripes, really, when compared to how much I like the car...
