A guide to problems, costs, maintenance and repair for your 2009 Hyundai Sonata

2009 Hyundai Sonata Problems

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.

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.

2009 Hyundai Sonata Recalls

The rear suspension is the attaching point for the control arms and other rear suspension components. Road salt and water can accumulate in and around the rear crossmember causing it to rust. Excessive rust could cause one or both rear control arms to separate from the crossmember resulting in a sudden change in vehicle handling, increasing the risk of a crash. Dealers will inspect the rear crossmember and repair or replace it as necessary to correct this concern.

Now I have to pay out ...
