Common Problems, Issues, Recalls, and Reliability

  • Door Locks Malfunction Not Allowing Driver or Passanger to Open Their Doors

    A faulty door latch assembly may cause one or both front doors to be difficult to open. Replacing the worn latch will commonly correct this problem.

  • Faulty Throttle Position Switch

    Check Engine Light illumination—combined with a lack of power or a stumble on acceleration—may be caused by the throttle position switch (TPS). Kia released an improved part which should correct this concern.

  • Software Update Available to Correct Transmission Issues

    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.

  • Kia Issues New Alternator to Replace Weak One

    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.

  • Failure of AC Compressor Clutch

    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.

  • Crankshaft Position Sensor May be Damaged if Timing Belt Breaks

    Timing belts can break prematurely and cause serious engine damage. When replacing a broken timing belt, the crankshaft position sensor should also be replaced as it most likely has suffered damage as well.

  • Use Only Kia Approved Transmission Fluid

    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.
