Replacing the faulty clutch assembly does not necessitate replacement of the complete AC compressor or evacuation and recharging of the air conditioning system.

Most reported 2003 Kia Sedona problems
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.
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.
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.
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.
Whenever the temperature drops below 40 degrees the doors will lock automatically even if the keys are still in the ignition and the van is running! Took vehicle back to dealership multiple times but dealership apparently could not duplicate the problem therefore the locks were never fixed. I have had my van for about eight years now and the only solution I have is to carry extra keys!
