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 stereo/CD player refuses to load, eject, or play CDs, remove the power supply (fuse) to the stereo for twenty seconds to reset the stereo's internal memory.

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.

In cold, wet climates, the driver and passenger door handles may stick, jam, or not return to their rest position; improved handle release cables are available to correct this issue.

Make sure the transmission is filled with Kia-approved transmission fluid and at the correct level. Our technicians tell using incorrect transmission fluid or operating the transmission when it is low on fluid can result in internal transmission damage.

Reprogramming the transmission control module with the latest Kia transmission software may fix abnormalities in the automatic transmission and erroneous transmission-related Check Engine Light illumination. Software updates are commonly most effective on newer vehicles. Higher mileage vehicles may exhibit a similar symptom caused by a component failure. However, whenever major transmission repairs are performed the transmission software should be checked and updated as necessary.
