 Followed the recommended timing change and water pump replacement at a KIA dealer in Fair Lawn, NJSUV developed starting problems, rough engine idle, then loud noises and violent shaking motions in the engine.Dealer in TN diagnosed broken timing change with metal fragments in the engine, requiring engine replacement.Opted to sell vehicle for parts rather than the expense of repair.There was a class action lawsuit regarding this problem with the 3.8 L engine.  The class action was ultimately denied.This was my second Kia Sorento.This will be my last KIA.
