“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.”

NHTSA complaint #10875587, filed 2016-06, 145,000 miles

“Was having my tires changed when mechanic noticed a significant amount of rot on the frame on the right side rear where the arm connects to the frame. High potential for the arm to pull out of frame which could cause a loss of control of the vehicle. Car started rusting around fenders and rockers 4 years ago. This frame rot is a structural integrity issue. Contacted Kia and said that due to mileage and year that it was not their issue regardless of the 3 previous claims I found on the NHTSA site and the fact that it is a manufactures defect.”

“My 2003 Kia Sorento start vibrating as I was pulling into my driveway and before I can park it I heard a load noise and my steering wheel became very heavy to steer and almost loose control. I had a mechanic look into the issue and found the pulley bolt (harmonic balancer) broke in half. I had also check if this is an unusual problem - came to find out that this could potential design defect from Kia. As there are thousand of them that has similar problem complained on the internet. I had called Kia dealer ship and they are not helping on this design flaw issue.”

NHTSA complaint #10487856, filed 2012-12, 10 miles

“I purchased my 03 Kia Sorento in 2004 and have had many issues since then. I have had to replace lights from the front to the back numerous times. I've been driving down our remote country road at night and had my headlights go out. My coolant tank cracked and left me stranded on another country road in the snow last year. I later found out it was recalled for that particular defect; after I had it replaced. The lighting issue is my biggest concern right now because of where I live (remote country roads, deer at night, etc) I have to have properly functioning headlights at all times. …”

NHTSA complaint #10296669, filed 2009-12, 45,000 miles

“While the car was in for an oil change the tech noticed a couple of brake lines looked wet, when they where checking the lines they noticed the rear sub-frame which the lines were connected too was totally rusted out. The car is no longer drivable due to the fact that this sub-frame holds the rear differential in place.”
