Hyundai Sonata Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Hyundai Sonata

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.

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.

Problems with the accelerator pedal position switch may cause the Check Engine Light to illuminate; an improved switch is available to fix this problem.

I own a 2005 6cyl Sonata. Purchased it with 15k miles. Have taken outstanding care of it thru out the years.
