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

Hyundai Sonata Recalls
These vehicles are being recalled because the transmission shift cable may come loose from the shift lever pin. If this were to occur, the gear selected may not match the indicated gear and the vehicle could move in an unexpected direction. Also, if the parking brake is not set when the vehicle is parked, the vehicle could roll unexpectedly even if the indicated gear is "park". Dealers will inspect and repair the connection between the shift cable and the shift lever to correct this concern.
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.

I have a 2010 hundai sonata two years in and there is a dilemma with my starter.
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 own a 2005 6cyl Sonata. Purchased it with 15k miles. Have taken outstanding care of it thru out the years. Has been a wonderful car; however, it lately has been making a ticking/tapping noise on a cold start, and goes away once it's warm. 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 ...
