NHTSA Complaint #11672904 — 2021 KIA SORENTO

My 2021 Kia Sorento (VIN: [XXX] , built July 2021) has a persistent scraping/metal-on-metal noise when turning the steering wheel. This noise comes from inside the steering column. It matches exactly what Kia documents in TSB CHA111, which identifies failure of the worm shaft small bearing inside the C-MDPS (Column-Mounted Motor Driven Power Steering) system. My vehicle uses the same steering column system covered in that bulletin, though my VIN is not included in the bulletin’s range. The video embedded in CHA111 features the exact noise my vehicle is producing. I recorded it and sent it to Kia Consumer Affairs, along with proof of the C-MDPS configuration and production date. Despite clear evidence that my steering system is affected by the same design flaw, Kia declined support unless I pay for a dealer inspection — despite the issue being a known, documented defect. This noise has been present as far back as I can remember. and is steadily worsening. The steering column bearing is a critical safety component. If it fails, it could lead to steering resistance or failure. Other Kia and Hyundai vehicles using this system have already had the part replaced under warranty or goodwill coverage. I can provide a video of my vehicle making the noise. I’m submitting this complaint because Kia refuses to address a defect they’ve already acknowledged when it appears in later VINs. I am asking NHTSA to investigate and consider requiring Kia to expand the scope of TSB CHA111 or issue a recall.
