NHTSA Complaint #11655121 — 2014 KIA SOUL

Vehicle Information: 2014 Kia Soul (Base Model) VIN: [XXX] Approx. Mileage at Failure:91,000 Incident Date: [XXX] Complaint: On [XXX], the catalytic converter in my 2014 Kia Soul failed. This follows the completion of recall SC176 on July 14, 2022, which addressed excessive exhaust gas temperatures caused by abnormal combustion conditions. While Kia representatives have claimed that SC176 is unrelated to the catalytic converter, it’s well understood that excessive exhaust heat can lead to long-term thermal damage to emissions components—particularly the catalytic converter. One representative even appeared concerned about the implications of SC176 during a phone call, before quickly changing direction. I believe this catalytic converter failure is a delayed consequence of the issue SC176 was meant to address, especially since the converter is part of the affected exhaust system. This failure not only poses a financial burden—since it falls outside the federal emissions warranty—but may also reflect a broader issue that other 2014 Soul owners could face. The component failed resulting in immediate loss of power on a US interstate highway. I’m requesting NHTSA investigate whether catalytic converter failures like mine are in fact related to the defect addressed in SC176 and whether Kia should be required to offer further coverage or corrective action. Additional Information: I can provide documentation upon request, including: •Receipts showing consistent oil changes and routine maintenance •Service records for all recall work performed on the vehicle, including SC176 (completed on 7/14/22) •A repair invoice for the catalytic converter failure (currently pending — my vehicle is still at the service department as of today, 4/16/25) •A timeline of communications with Kia Customer Care Please let me know if any of these are needed to support further investigation. I’ll gladly provide them once available INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
