When go to shift truck in drive it makes a clank sound and when driving at a speed between 65-70 the truck starts vibrating, and when in reverse it squeaks when back up, at first my wife it was the U joints so we had it replaced but it all started happing again. Next our battery die had it replaced with a new one now the air bag indicator light stays on all the best time and at times it feels like the accelerator peddle gets stuck at times.

Sorento 4WD 6-cyl

  • 135,000 miles
I have service records showing I had the crankshaft pulley replaced at 55,000 miles under warranty by Kia. The crankshaft pulley broke off at 105,000 miles. I was able to have the vehicle repaired cost $1500 out of my pocket. On 1/11/2015 the crankshaft pulley broke off for a 3rd time, shearing the threads to the engine, and causing the engine to no longer work. All 3 events caused loss of power and able to steer the vehicle.

The bolt on the crankshaft pulley as well as the pin broke off causing the motor to stop and overheat dumping all the antifreeze and stopping all belts. My mother could have been injured while driving but it ended up being she was just blocking traffic thankfully and not on the highway. This seems to be a very common issue with hundreds if not thousands complaining about the crankshaft pulley bolt and pin. Kia says they won't do anything as it is out of warranty and I am not the original owner. This may have been fixed once before on the vehicle due to failure and I am very worried this may happen again with worse consequences. My mechanic was able to provide a temporary/permanent fix but we really dodged a bullet and it could have caused immediate catastrophic damage. I'm disappointed with all of the serious complaints that Kia still has not recalled it for 2002-2009 Sorento models.

problem #3

Sep 172012


  • 26,000 miles
The contact owns a 2003 Kia Sorento. While driving 70 mph, the vehicle failed to accelerate. The contact moved the vehicle off the roadway and the engine rpms increased as the vehicle began to perform normally. The contact also stated that once the fuel tank was below 3/4 full, the engine would lose power and began to idle. The vehicle was taken to a dealer where it was inspected but was neither diagnosed nor repaired. The manufacturer was made aware of the issue but provided no assistance. The approximate failure mileage was 26,000.
