2003 Hyundai Sonata ProblemsCheck Engine Light and Transmission Won't Shift Correctly
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.
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 QuestionsWHAT DO I REPLACE WHEN MY REMOTE WILL NO LONGER OPEN MY TRUNK? (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?
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.
