What is different on the 2021 Kia Sportage
The vehicle-specific detail — not the generic version of this fault.
This is an electrical fire risk rather than a braking performance problem, and it is unusual in that it can occur with the vehicle switched off and parked. Kia's recall guidance for affected vehicles has included parking outside and away from structures until the remedy is performed — which tells you how the manufacturer assesses the risk.
- The remedy has generally involved replacing a fuse in the HECU circuit and, where necessary, replacing the control unit itself.
- A warning sign is the ABS light illuminating, though the recall condition can develop without any dash warning at all.
- A burning or electrical smell from the engine bay after shutdown should be treated as urgent on an affected vehicle.
- Check the recall status by VIN. Coverage is defined by build date, and two 2021 Sportages can have different status.
