Problem overview

Some Mercedes-Benz GL450 owners report experiencing issues with the airbag light being on and receiving failure messages for all seats, indicating a potential problem with the airbag system that requires immediate attention. These issues may stem from a depleted car battery, which can trigger the airbag light as the system's backup battery depends on the main battery. Additionally, some owners find that there may be actual faults within the airbag system or issues related to sensors and suspension airbags, necessitating inspection by a qualified mechanic. In cases where the problem is linked to a dying battery, replacing the battery and manually resetting the SRS/Airbag light may resolve the situation. However, it is advisable for owners to seek professional assistance to thoroughly diagnose and address any underlying airbag system issues to ensure the safety of all vehicle occupants.
