Known Problems

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.

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.

    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.

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.

A failing vapor canister purge valve may cause the Check Engine Light to illuminate. This valve is part of the evaporative (EVAP) emission control system.

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

A defective exhaust gas recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.

Engine stalling or failure to start may indicate crankshaft angle sensor failure; Hyundai issued a recall.

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.

If the alternator fails, it should be replaced with an improved design which is better able to replenish electrical power to the battery. The new alternator requires a different diameter drive belt.

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.
