2003 Hyundai XG350 Problems

Drive Train -- Verified

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.

Engine -- Verified

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

Electrical & Lights -- Verified

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.
