Known Problems

In order to correct a problem that results in difficulty starting, engine vibration, or a rattling sound from the engine compartment, Kia released an updated crankshaft pulley bolt.

One or both head light bulbs may burn out prematurely requiring replacement. There have also been reports of other bulbs burning out often as well.

The airbag warning light may illuminate erroneously.  This can be caused by an internal defect in the control module. Replacement of the airbag control module with a revised part may be necessary to correct this concern.

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.

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.

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.
