Known Problems

Hyundai issued a recall on the airbag computer; it needs to be reprogrammed to prevent the airbags from deploying incorrectly during an accident when a child car seat has been placed in the passenger front seat.

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.

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.

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

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

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

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

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.

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.

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.
