I have had issues galore with my car since the day I drove it off the lot. First issue and still is just gave up on bringing it back was the steering that drifted. Then I had a sound coming from the rear of the car that made a loud noise. I also have a sound coming from the sun roof. After that I had a oil leak in it's first year. My radio went out, my driver window stop working. My turbo quit on me. Battery died. I was stranded by the car 3 times. It would turn over fast but not crank. I called road side on one of those. My air bag lights come on while driving down the road. It rattles like cheap parts. I have called Hyundai with no response as of yet. The dealership says they can't do anything. I pay a car not for a car I don't trust to drive.

I recently bought a Hyundai Sonata SE 2.0T on Oct 26 2012, ever since I bought it, I've realized that the mpg that it gives me is 17 no matter if I'm in city or highway, while minimal estimates are 23 in the city. I've looked on Hyundai forums and it seems like I'm not the only one with this issue. Contact with the dealers has been nothing but a pain, they continue to argue with me that, that is impossible and won't even take a look at the vehicle. I've been to two separate dealers with the same outcome.
