I've been driving my 2011 Elantra now for 9 months. I have a major complaint about the navigation system. It does not follow major highways and fastest routes. It takes you down every country road and very strange routes. Hyundai needs to update the system to better software now. I've tried using the alternate route option, but that just makes things worse. Also, everytime the car is stopped and I press the gas, both in reverse and forward, the rearend is making a pinging sound. I'm not sure what it is yet, it could be the brakes or something in the rearend. One additional problem that I am having is vibration of the engine w/ AC on. The steer wheel vibrates and something under drivers seat.
Improve the navigation software. Fix A/C related engine vibration.
