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.
If you experience excessive engine noise on startup (after the engine has been turned off for several hours) that lasts for more than five or six seconds, turn off the engine and check that the engine oil level is correct. If the oil level is correct, the noise may be caused by the timing chain tensioner. Hyundai has an improved tensioner to correct this 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.

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.
