2005 Hyundai Sonata Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2005 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 bought this car w/19,000 miles on it. I haven't had any problems at all in the 45,000 miles I've put on it since. The 60,000 mile warranty check-up was a little pricey because of the timing belt replacement, otherwise this car has been economical to own. The V6 is still smooth and quiet and is a joy on trips. This model looks a bit like a Jaguar but without the price. Hyundais have come a lon...
