2007 Hyundai Azera Limited 4dr Sedan w/XM (3.8L 6cyl 5A)
The first 2 months, 2000 miles, it drove and idled extremely smooth. A vibration or shake started at about 2 months. This has progressively gotten worse. The tires have been balanced twice and rotated once. Still the shake or vibration continues. It is in the steering wheel, the seat, and the floor board. The dealership says that it is driving normal. It also has started idling rough. Although it only started this about 2 months ago, the dealership says it, too, is normal.
I loved my car to begin with, but now I am extremely concerned that there is a problem that will continue to get worse.
