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.

Improved Alternator Available

If the alternator fails, it should be replaced with an improved design which is better able to replenish electrical power to the battery. The new alternator requires a different diameter drive belt.

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.

2003 Hyundai Sonata Questions

WHAT DO I REPLACE WHEN MY REMOTE WILL NO LONGER OPEN MY TRUNK? (1 answer)

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?

DO TRANSMISSIONS HAVE BELTS? (2 answers)

MY BOYFRIEND TOLD ME TRANSMISSIONS NO LONGER HAVE BELTS. WHEN I AM DRIVING THE TRANSMISSION SOUNDS LIKE IT IS SLIPPING SOME BEFORE THE GEARS CATCH. i BELIEVE ITS THE BELTS THAT HAVE WORN . AM I RIGHT OR IS IT SOMETHING ELSE. ALSO THE RPMS DON'T GO OVER 2500. I WAS TOLD I'M OK THERE.

2003 Hyundai Sonata Reviews

Battery keeps dying, I guess I have to replace it and I need a relay switch to the fan for the radiator. I go on line to ROCK AUTO PARTS. COM. I SHOPPED ON LINE AND COMPARED PRICED, ILL NEVER BUY PARTS FROM AUTO ZONE OR O'REILYS AGAIN. VERY REASONABLY LOW PRICED PARTS. I'm on a fixed income so I really have to be fruggle. You should visit this place.
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
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.
