The airbag control system in your vehicle has a sensor that checks if everything is working properly. In some 2021 models, this sensor may not send the correct signal to the control module, causing the airbag warning light to flicker on and off.
Risk if Unfixed
If the airbag warning light doesn't stay on when it should, you might not be warned about a critical airbag system problem, which could lead to serious injury if the airbag doesn't deploy when it's supposed to.
Free Fix
Your dealer will update the software in your vehicle's control module, free of charge, to fix the issue. You can expect a notification letter soon, or you can contact your manufacturer directly for more information.
