2004 Hyundai Sonata Problems
On the 2.7L V6 and 2.4L 4 Cylinder, a defective exhaust gas recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.
Parking lights not turning off intermittently or all the time. The common problem is with the cabin fuse box. Complete replacement of the assembly is necessary to fix the problem.
Problems with the accelerator pedal position switch may cause the Check Engine Light to illuminate; an improved switch is available to fix this problem.

But, all in all I'd buy another one-...
I bought the car new and it still is like new. I had the brakes done, transmission maimtinance, and just the basics up keep. I love to drive it. It has such great pic-up , even at 135,000 miles. It rides like it is gliding above the ground. The most smooth ride I have ever experianced.As smooth as the Lincoln we had. I would ecomend the Hyundai to everyone.
