2012 Hyundai Sonata Problems
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.
If you experience excessive engine noise on startup (after the engine has been turned off for several hours) that lasts for more than five or six seconds, turn off the engine and check that the engine oil level is correct. If the oil level is correct, the noise may be caused by the timing chain tensioner. Hyundai has an improved tensioner to correct this problem.

2012 Hyundai Sonata Recalls
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 engine during manufacturing may have retained metallic debris from the crankshaft. Presence of this metallic debris could cause engine noise and failure. Dealers will inspect and replace affected engines as necessary, and extend the warranty of the engine short block to 10 years / 120,000 miles free of charge to resolve the concern.
These vehicles are being recalled because the transmission shift cable may come loose from the shift lever pin. If this were to occur, the gear selected may not match the indicated gear and the vehicle could move in an unexpected direction. Also, if the parking brake is not set when the vehicle is parked, the vehicle could roll unexpectedly even if the indicated gear is "park". Dealers will inspect and repair the connection between the shift cable and the shift lever to correct this concern.
