Driver's Frontal Air Bag Does Not Inflate Properly

The second stage of the dual stage driver's frontal air bag may not deploy properly due to a missing chemical enhancer necessary for the second stage deployment. Dealers will replace the driver's frontal air bag module free of charge to resolve the concern.

Power 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.

Brake Lights Stay Illuminated

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.

Hyundai Sonata Reviews

I bought my 2009 Hyundai Sonata in 2010. It was a great car and never had any issues with it. Have driven it cross country round trip 3 times.

The metal pieces from those old gears got into the oil pump and caused it to fail which...
Comfortable ride, a bit noisy with a/c, lots of electronic sensor and other mechanical issues that I experienced and read about but Hyundai has not been responsive to recall or covering under warranty.

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.
