In order to correct a problem with the Kia Sorento 3.5l V6 engine that results in difficulty starting, engine vibration, or a rattling sound from the engine compartment, Kia released an updated crankshaft pulley bolt.

UPDATE: A class action lawsuit brought against Kia Motors in regard to the breakage of the crankshaft pulley bolt on Kia Sorento models with the 3.5L V6 may provide relief to some customers who paid to have the repair performed at a Kia authorized repair facility. There are a few caveats, however:

  • Kia Sorento models from 2003-2006
  • Customer must have completed the repair before 100,000 miles
  • Repair performed at Kia authorized repair location
  • Must be the 3.5l V6 engine
  • The owner must have made a claim by May 17th, 2017
  • Exclusion from the claim is the only way to make further claims against Kia Motors for this issue
