Tl* the contact owns a 2003 Kia Sorento. While driving at 55 MPH, the steering wheel became difficult to turn. The contact had to apply force to the steering wheel in order to turn the vehicle. The vehicle was taken to an independent mechanic who diagnosed that the harmonica balance in the steering column needed to be replaced. The vehicle was repaired; however, the failure recurred. In addition, the contact noticed that there was an abnormal noise coming from the rear of the vehicle. The vehicle was towed to an independent mechanic who diagnosed that the harmonica balance needed to be replaced and the rear axle corroded and needed to be welded. The vehicle was repaired; however, while at an independent mechanic for routine service, the mechanic stated that the subframe was corroded. The manufacturer was not notified of the failure. The failure mileage was 79,000.
I was driving the vehicle in the parking lot when I heard a loud noise and lost control of the steering because the car died and the steering wheel locked up. I looked under the hood and notice all the belts and front of the motor fell off and was laying at the bottom. I called the tow truck they towed it to the Kia dealer. Where they told me its a problem the 2003 Kia Sorento has. They told me they will replace the engine that was at 38,000 mile. Now the car has 72,000 miles on it so that's 34,000 miles on this motor now they tell me the same thing is happening and the motor has to be replaced. So the Kia motor is only good for 30,000 miles that's just ridiculous and the cost is on me.
While driving I heard a clunk and a the car began rolling side to side. I limped to a mechanic and was told that the frame where the suspension and all parts connect was rusted out. Frame repair said this can not be fixed as the frame is rusted out. Where the stabilizer and suspension connects. Teh car only has 149,ooo miles and is in north carolina. I have read other reports of a rusted out support frame on this site. Will the manufacturer replace this frame.
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.
Takata recall the crankshaft pulley bolt keeps coming lose and this causes the steering wheel to become stiff. This happened in the middle of traffic and had to get it towed to a friends house. Currently the car is not driveable for over two weeks.
I bought a 2003 Kia Sorento from my niece back in November 2013 for $2000 and not even two weeks into owning this vehicle, the crank shaft broke in half! The bolt broke off in half inside the crank shaft pulley and the other half of the bolt was inside the crank shaft case. To my understanding, this is the second time that the crank shaft needed repairing (my niece, husband who were the first and original owners to this Kia Sorento had it break down on him on the freeway as well, had to get it towed to Kia then paid them to fix it when they owned the vehicle) but this time, when this issue happened again while I owned the vehicle, the crank shaft failed in a greater and more costly condition then the first time the crank shaft failed on them. …
I purchased the Sorento 5/31/03, while making a right hand turn the power steering completely went out; I almost hit another vehicle regaining control. Contacted Kia consumer affairs immediately, they have complete logs on file. 6/2/03 dealer replaced power steering rack. 6/10/03 830 miles,power steering failed again;had to fight with the steering to control vehile in parking garage.6/12/03 power steering pump was replaced. Picked up vehicle that evening and pulling out from the restaurant the power steering went out again. 6/13/03 850 miles, computer malfunction; new downloads had to be downloaded to vehicles computer. 6/18/03 electronic power steering module had to be replaced. Now 6/20/03 dealer said they wont help me, Kia consumer affairs said they wont replace the vehicle nor buy back the vehicle. I'm terrified to pick up the vehicle tonight. …
While driving on hwy 275 at 60 MPH. Engine lights came on and steering wheel locked..total system power failure..2 daughters almost lost their lives trying to maneuver this death missile to emergency lane..just in time to miss multiple tractor trailers vehicles from crushing them..not to mention multiple passenger cars in harms way from defective part replaced malfunctioning again... Kia claims no responsibility even though defective part is clearly at fault..have Firestone mechanic willing to substantiate claim and is willing to help in class action lawsuit.. I urge everyone that has any history with this deathtrap to please get the message out that this vehicle will kill you..most likely their other vehicles will as well...do not ever drive or put anyone you love in any vehicle that they make!!!!! …
While driving my daughter to school, vehicle lost steering in a turn causing us to narrowly miss hitting a utility pole. Vehicle had to be towed to service garage where they confirmed that the crankshaft pulley bolt had become loose causing the harmonic balancer pulley to wobble, break and cause damage to all surrounding engine components. $1700.00 repair did not work and issue recurred. After a second repair attempt, same issue occurred again this time with the crankshaft bolt having sheered off. Vehicle is a serious safety hazard, is not drivable at this time, and will this time cost minimally $3500.00 for a replacement motor....and potentially a life. It is imperative that the NHTSA mandate a recall on these vehicles as it is ludicrous to wait for a death or multiple deaths before acting on what I am well aware is a commonly reported and potentially deadly problem. …
