2003 Hyundai Sonata ProblemsParking lights don't turn off
Parking lights not turning off intermittently or all the time. The common problem is with the cabin fuse box. Complete replacement of the assembly is necessary to fix the problem.
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 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.

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?
