Hyundai Sonata Problems

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.

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.

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.

The affected vehicles are being recalled because the brake light switch can fail prematurely, resulting in the loss of brake light operation. Other systems that may be affected include: cruise control, push-button start, gear shifter, and Electronic Stability Control (ESC) system. Dealers will replace the brake light switch to correct this concern.

Hyundai is recalling certain 2012-2013 Sonata passenger cars, the side curtain airbags may inflate unexpectedly - Without a deployment command from the control module.

The Hyundai recall number is 106.

I was driving my 2000 Hyundai Sonata GLS and the brake and battery lights came on. They started out flashing then stayed on. When in park I revved the engine and the lights would go out then come back on. Later on in the evening I drove it again. The lights did'nt come on at first but then on again. So I stomped on the pedal to go and then it acted like my transmission was in neutral. the check...

I have a 2010 hundai sonata two years in and there is a dilemma with my starter.

My mechanic diagnosed it by ear only...says it's engine bearings and will probably need a new engine soon :(((( I need an expert to tell me otherwise. Does ...
