NHTSA Complaint #11564046 — 2015 KIA SORENTO

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.
