2003 Hyundai Sonata Problems

Rough Idle Due to Faulty EGR Switching Valve

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.

Transmission Won't Shift/CEL Due to Failed Speed Sensors in Transmission

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.

Crankshaft Sensor May be Damaged by Broken Timing Belt

Premature timing belt failure may result in serious engine damage. When replacing a broken timing belt, it is important to inspect and possibly replace the crankshaft position sensor; it is often damaged when the timing belt breaks.

2003 Hyundai Sonata Questions

will not start or try to crank over, all electrical works, battery is good (1 answer)

I have checked the fuses, I don't know what this could be. I drove it 9 hours earlier and it was fine. There has never been any kind of problem with it. The only thing I've noticed is the negative post cover is very loose. But do you have any other ideas?

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!
good car air dont work tho suckes
