Known 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.

The crankshaft position sensor may fail, causing engine stalling or a failure to start. Replacement or the failed sensor will commonly correct this problem.

    Parking lights not turning off intermittently or all the time. The common problem is with the cabin fuse box.  Complete replacement of the assembly is necessary to fix the 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.

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.

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 the automatic transmission does not shift properly and the Check Engine Light illuminates, the speed sensors in the transmission may have failed. The sensors are simple and inexpensive to replace.

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

The timing belt can fail prematurely; if it fails while driving, it can cause catastrophic damage to the engine. Be sure that the timing belt is inspected and replaced according to the manufacturer's recommended schedule.

The manual transmission may become difficult to shift into third gear. This is common caused by worn synchronizers. Our technicians tell us that revised synchronizers are available to correct this concern.

Hyundai Genesis 4.6 models equipped with navigation units may suddenly stop playing audio from all speakers. This includes sound from CD players, radio, navigation, satellite radio, and telephone calls. All other features may still function properly.

This fault requires no part replacement, and is a software glitch that can be rectified by a 'hard reset'.

To perform the hard reset, simply disconnect the vehicles negative battery terminal, wait 15 minutes, and reconnect the negative battery terminal.
