2004 Hyundai Sonata Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2004 Hyundai Sonata

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.

Problems with the accelerator pedal position switch may cause the Check Engine Light to illuminate; an improved switch is available to fix this problem.

    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.

My husband said I would love it (he was a salesman for a Hyundai dealership), and I DID! It is the best car I have ever owned. Very low maintenance and the little things that have had to be repaired, ie., electric side mirrors, some fuses, gas door won'...

We have owned this car for 5 years -63000 miles and it has been pretty good car. Just a few problems with the electric motor on the mirrors; A/C fan motor and switch; and the horn went bad. One thing I hate about this car is the windshield wipers-they don't go fast enough-terrible in these Florida storms! Plus, the seats are not really all that comfortable. 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.
