What the official procedure directs
Owners are advised to park their vehicles outside and away from structures until the interim action is complete. Hyundai will notify owners, and as an interim action, owners have the option to follow provided instructions to perform a battery update through the vehicle's infotainment system or request a Hyundai dealer to provide the update. Once parts are available, dealers will inspect the Battery System Assembly (BSA), and replace it if necessary.
Mileage context
Safety recall eligibility is based on the VIN and campaign scope, not ordinary warranty mileage. Check the complete VIN even when the vehicle is outside its original warranty.
