NHTSA Complaint #11676487 — 2021 KIA K5

I am submitting this complaint regarding ongoing and unresolved safety issues with my Kia K5, which I believe are directly related to a known recall involving the ECM (engine control module) and/or fuel system. My vehicle continues to jerk and misfire during acceleration, and it has even stalled at idle on multiple occasions — creating a serious safety concern for myself and others on the road. I have already completed the recommended repairs, including new ignition coils and spark plugs, yet the problem persists. Despite these symptoms aligning with known recall-related issues, Kia of Orange Park (Florida) has refused to fully diagnose or investigate the matter, citing that the recall does not apply in my case. However, the symptoms match those outlined in other ECM/fuel system-related recalls, and this is not the first time this dealership has failed to properly address mechanical concerns. Previously, I had to escalate an A/C issue to Kia Corporate, which only resulted in a resolution after a recall was issued right before my vehicle was set to be returned with the same issue. That situation makes me extremely concerned that my current safety concerns are again being ignored and will only be addressed after a broader recall is issued. I am requesting that the NHTSA investigate this matter, as I am worried this defect may affect other vehicles and poses a safety risk that Kia and its dealerships are not taking seriously. Thank you for your attention and action.
