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.

208 vehicles are being recalled because the may have been assembled with an incorrect left drive axle. This could result in separation of the left axle from the transaxle differential. If this were to occur the vehicle would stop moving, increasing the risk of a crash. Additionally, the vehicle could roll unexpectedly while parked. Dealers will inspect the left drive axle and replace it as necessary.

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.

An electrical problem with the vehicle may lead to loss of power steering and an inability to shift the vehicle from 'Park'. Low speed maneuvers while parking may be especially difficult with heavier steering feel, and may cause loss of vehicle control.

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 ...
