2023 Kia SorentoRecalls, problems, MPG & safety

“Subject: Request for Review of Potentially Related Electrical Overheating – Kia Sorento HVAC Harness Recall SC351 / NHTSA 25V649 I am requesting that NHTSA review an electrical overheating issue involving my Kia Sorento and consider whether it could be related to the existing HVAC blower-motor resistor harness recall, SC351 / NHTSA 25V649. My vehicle experienced overheating at a terminal on the main relay in the under-hood fuse box. The overheating spread to and melted part of the fuse box. Kia inspected the vehicle in person and informed me that the overheated relay terminal belongs to a different circuit from the HVAC resistor harness involved in the recall. I understand Kia's position that these are separate circuits. However, I have not received a detailed technical explanation identifying the root cause of the relay terminal overheating or explaining the basis for ruling out any relationship to the recalled wiring defect. Kia has offered approximately $2,200 toward an estimated $3,900 repair through a goodwill program, leaving me responsible for approximately $1,700. I am concerned about both the safety implications of the electrical overheating and…”

“My 2023 Kia Sorento has experienced continuous mechanical failures, including a serious engine fire in December 2025 while I was driving on the [XXX], which put my life at risk. Following that incident, my vehicle remained in the shop for nearly three months while the engine and related components were replaced, only to experience another failure in March 2026 requiring a transmission replacement, followed by electrical issues in April requiring a wiring harness replacement. In June 2026, my vehicle broke down again and required yet another transmission replacement, leaving me without my vehicle for several additional months. [XXX], my vehicle failed AGAIN while I was in Houston and had to be towed, proving that nearly a year of extensive repairs has failed to resolve these ongoing mechanical issues. This vehicle is a serious safety concern, and I have completely lost confidence in its reliability, especially after experiencing an engine fire, repeated breakdowns, and dangerous acceleration issues. I have continued making monthly payments on a vehicle that has spent more time in the repair shop than in my possession, causing significant financial strain,…”

“The vehicle experienced a sudden transmission malfunction while operation on public roads. The check engine light illuminated on the dashboard, and a diagnostic scan from the app revealed active error code P1C2D03. This specific component failure looks like it relates directly to Kia Safety Recall SC250 (NHTSA Campaign 22V760) regarding the 8-speed Dual-Clutch Transmission (DCT). Although my specific vin shows no active recalls. The failure presents an immediate safety risk as it causes an abrupt, unexpected loss of all motive power while driving in traffic.”
