Known Problems

The Kia Sedona is well known for presenting issues to the operator when trying to start the engine. This is especially true for vehicles with the Kia smart key. 

An issue with the factory vehicle immobilizer control module can cause the vehicle to think it is being stolen. This will immediately disallow the vehicle from starting. 

Many times, the key is the issue, and vehicles with keyless go or push-to-start technology may function properly if the key is inserted (check owners manual for the location of the port). 

The newest version of the smart key can be used to press the start button, which will allow the vehicle to register the key when the battery is low. 

If these quick tips do not allow the vehicle to start, or the vehicle does not use a smart key, diagnostics will need to be performed by a factory authorized Kia service enter. 

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.

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.
