One problem related to warning light on has been reported for the 2021 GMC Yukon. The most recently reported issues are listed below.
I received the car on 9/8/2020, I started noticed a error message on 19sep2020, that stated service safety restraint system with the airbag warning light coming on. This light comes on and off so there is no way to tell for sure if the airbag is working appropriately. The message comes on both if you are in motion or stationary.
