2003 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.

Concerned about safety, the NHTSA is investigating reports of rust forming at the front suspension mounting points, the frame, and the sub-frame. Some of these vehicles may have been recalled for this issue. For more information, please click here»

If the automatic transmission does not shift properly and the Check Engine Light illuminates, the speed sensors in the transmission may have failed. The sensors are simple and inexpensive to replace.

2003 Hyundai Sonata Reviews

I bought my 2003 Hyundai Sonata new, and now at 102,000 miles, it still runs like a top. I haven't had any major repairs on it. The only issues are that about 4" of paint have chipped off on the hood, and the interior chrome is chipping as well. Mechanically, it is the most reliable car I've ever owned.

This car is comfortable, peppy, and fun to drive. I love the side shift option and the fact that it is pretty good on gas. I own the 2003, 4 Cylinder model and it has been extremely reliable. I replaced the timing belt at around 85,000 miles and I just replaced the spark plugs today. I intend to keep this car for a long time to come. It is stylish and sporty, and I love it!

Our 2003 V6 has been in the auto repair shop for three weeks now they repair man says he has one fuel line and that the other is on back order, we even called the mfg, he was nice but still no results,tired of waiting. help
