Known Problems

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.

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

After the vehicle has been operated with electrical loads (lights, air conditioning), a weak alternator can cause starting difficulties. In some cases, the original alternator could not sufficiently charge the battery; Kia released a new alternator which can correct this concern.

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.

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.

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.

A defective AC compressor clutch assembly can cause excessive noise or vibration when the air conditioning is on. Improved parts are available. Replacing the faulty clutch assembly does not necessitate replacement of the complete AC compressor or evacuation and recharging of the air conditioning system.

In warm weather, the power sliding door switch may get stuck in the open position. Kia has an improved switch to correct this problem.

An engine misfire may develop due to a failed ignition coil. Our technicians tell us one coil is used for each cylinder. If one fails, often times another is not far behind. It may be worth considering replacing all the coils if a failure is encountered.

The Check Engine Light may illuminate with the code stored signifying the engine is not reaching normal operating temperature. If no fault is found with the components of the cooling system, a simple reprogramming of the powertrain computer will commonly correct this problem.

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.
