Known Problems
Difficulty starting the vehicle may be caused by a defective vehicle immobilizer (anti-theft) control module.

The navigation unit in the Kia Sedona 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 parts 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.

If the engine is excessively noisy on startup (after the engine has been off for several hours) and the noise lasts more than four or five seconds, turn off the engine and check for correct engine oil level. If the oil level is correct, the noise may be caused by the timing chain tensioner. Kia released an updated timing chain tensioner to solve this problem.
