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.
Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct. Also, make sure the computer that controls the transmission has the most up-to-date adaptive programming information. When servicing these transmissions be sure to use fluid approved by Hyundai.
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.

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?
Hyundai Sonata RecallsPower Steering Assist Fails
The electronic power steering circuit board may be damaged and result in a loss of power steering assist. Dealers will replace the control unit for the electronic power steering free of charge to resolve the concern.
The brake pedal stopper pad can deteriorate, resulting in the stop lamp switch plunger to remain extended when the brake pedal is released. This will cause the brake lights to stay illuminated, and will allow the automatic transmission shift lever to be moved out of park without depressing the brake pedal. Dealers will replace the brake pedal stopper pad with an improved part free of charge to resolve the concern.
The anti-lock brake system warning light may not illuminate, and may fail to indicate a problem with the system to the driver. Dealers will update the anti-lock brake system control unit software free of charge to resolve the concern.
