2024 Kia SportageRecalls, problems, MPG & safety

“1. COMPONENT & INSPECTION: Electrical System / CAN-Bus network architecture and gateway modules. The vehicle and parts are available for inspection upon request. 2. SAFETY RISK: The CAN-bus drops communication while driving at road speeds. Critical safety systems—including Forward Collision-Avoidance, Blind-Spot Monitors, and Electronic Stability Control—instantly shut down mid-trip. Losing active stability and driver assists while moving on public highways poses an immediate, severe crash hazard to myself and others. 3. DEALER CONFIRMATION: Yes. An authorized Kia dealer scanned the vehicle and confirmed multiple logged historical network communication error codes (U-codes), verifying a system-wide network failure. 4. OTHER INSPECTIONS: Inspected only by the Kia dealer technician. However, because the failure is intermittent, the dealer simply cleared the fault codes and released the vehicle without performing physical diagnostics or repairs. Kia America Corporate opened a consumer case but has since ghosted all communication. No police or insurance inspections have occurred yet as a crash has not yet happened. 5. WARNING LAMPS & FIRST APPEARANCE: No advance…”

“The vehicle experiences an intermittent, severe safety malfunction tied to the Idle Stop & Go (ISG) auto-stop system. When brought to a complete stop at intersections or red lights, the engine shuts off normally to conserve fuel. However, when releasing the brake pedal, the engine completely fails to auto-restart and stalls out in live traffic. The vehicle locks up, flashes an error message on the instrument cluster instructing the driver to shift to Park or Neutral to restart, and requires a hard manual key cycle to get the vehicle moving again. This intermittent defect has occurred over the past year, creating an extreme hazard for rear-end collisions in high-traffic intersections. The component is available for inspection upon request. The vehicle was presented to an authorized dealership on October 21, 2026, at 31,985 miles specifically for this stalling defect. The technician documented the complaint on the Repair Order but was unable to duplicate the stalling during a brief road test, noting that values were within factory specifications at that moment and taking no repair action. The manufacturer has not yet issued a recall or permanent remedy for this…”

“I am reporting a concern regarding the Forward Collision Warning and Automatic Emergency Braking systems on my 2024 Kia Sportage SX Prestige. I have been attempting to understand the operating behavior of the vehicle’s FCA system using cardboard boxes as targets. I conducted observations at very low speeds (approximately 5 mph) as well as at approximately 30 mph. During these observations, the vehicle did not provide a forward collision warning or automatic braking at distances at which I expected the system to recognize a potential collision. I have not intentionally caused a collision or placed a person or another vehicle in danger. I am uncertain whether this behavior represents normal FCA operating limitations, the use of an inappropriate target, or a malfunction or calibration issue. I am therefore reporting the concern rather than asserting that a defect has been established. I am also uncertain what diagnostic or functional validation procedure Kia provides for this system. I have been able to find information regarding radar alignment, camera calibration, and diagnostic fault checking, but I have not been able to determine whether Kia provides dealers…”
