2015 KIA SORENTO Wheels Problems

Rear Coupler parts. Yes it is available for inspection on request. My safety was put at risk, #1 the rear wheels lock when turning, and makes a horrendous noise whilst turning. I live in a snowy state so this is very dangerous to have wheels lock up and have tires shredded. This is my third set of wheels as we just figured out the issue (coupler) this could cause accidents and hurt/injure/cause serious bodily harm to others. I have tried reaching out to the dealership but they said it is out of warranty and the dealership gave an outrageous quote. They have not inspected it but it has been reported to them. The vehicle has been inspected by a mechanic and confirmed it is the coupler, while steering and shredding the tires. There were no lights or warning signals, it just happened while turning.

BEARINGS, SUSPENSION AND STEERING ISSUE: TOOK CAR TO GET TIRE CHANGED AND EVER SINCE THE BEARINS AND STEERING IS OFF. STEERING WHEEL SHAKES ONCE I TRY TO GO FASTER THAN 55 MPH.

KIA DEALERSHIP ROTATED TIRES. REAR DRIVER SIDE TIRE FLEW OFF VEHICLE WITHIN 2 BLOCKS OF DEALERSHIP SERVICE DEPARTMENT. ALL LUGS MISSING. EXTENSIVE DAMAGE TO REAR END DEALERSHIP CLAIMS ALL LUG NUTS WERE PROPERLY ATTACHED AND THE ATTACHMENT WAS WITNESSED BY 2 TECHNICIANS. IF THIS IS TRUE THE WHEELS CAN FLY OFF OF THIS VEHICLE AT ANY TIME. I WANT THEM TO VIDEO ALL FUTURE WHEEL SERVICE AND RECALL ALL PREVIOUS WORK. THEY COULD KILL SOMEONE.
