The most common problems with the Kia Sorento include issues with the headlamps and the failure of the air conditioner compressor clutch. The failure of the ignition coil is also common.
Kia Sorento headlight bulbs often burn out before they are supposed to, requiring replacement. Numerous reports cite other bulbs in the vehicle burning out as well. A defective compressor clutch assembly in the air conditioner sometimes causes vibration or excessive noise when the air conditioner is on. While this flaw requires new parts to fix, in most cases, the entire air conditioning compressor does not need to be replaced, nor does the unit need to be recharged.
