This model of Sonata is miserable failure. I do not know from where to start. Before I purchased it, I drove it three times just to make sure it does not have that pull to the left issue. Unfortunately, after 10k miles I have front tires uneven wear. Dealer states that nothing is wrong with tires although even 1st grader would see difference between even and uneven tire wear. Contacted Hyundai and they refused any responsibility. Rest assured - they will make sure you don't get solution to tire (?) problem. I did not notice it before but steering wheel is not placed centered to the driver's seat. It is at about 1 inch offset to the left. Radiator leaked at 10k miles. Fixed under warranty.
Fix the pulling, tire wear, alignment issues. You are destroying good reputation of this car. As far as I am concerned, you can easily close the door for good. After 4 Hyundai cars I had, I am done with Hyundai. After all, new thinking, new possibilities ... Honda anyone?
