Seat Belt Reminder Light on a GMC Hummer EV
This is usually informational. Address it at your convenience.
What the Seat Belt Reminder Light Means on a GMC Hummer EV
The seat-belt reminder on a GMC Hummer EV lights (often with a chime) when a front occupant is unbelted. If it stays on despite everyone being buckled, a belt buckle switch or an occupancy sensor may be faulty.
How Urgent Is the Seat Belt Reminder Light?
In terms of priority, treat this as a low concern on your GMC Hummer EV. The single most useful thing you can observe is whether the Seat Belt Reminder Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the GMC Hummer EV drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.

The Seat Belt Reminder Light on your GMC Hummer EV is one data point, and the symptoms around it are the rest of the story.

Is It Safe to Drive With the Seat Belt Reminder Light On?
Safe-to-drive depends on judgement, and here is the technician's version for a GMC Hummer EV: respect the colour, respect the behaviour.

If everything feels normal and the light is amber, a short, cautious drive to a garage is typically fine, provided you do not delay the actual diagnosis.
Professional Mechanic Tips
Sticky or crumb-filled buckles fail intermittently; a careful clean of the receiver fixes many phantom belt lights.
A bag of shopping on the passenger seat of a GMC Hummer EV often sets off the belt chime — buckle the empty seat or move the bag to the floor.

Can I keep driving with the Seat Belt Reminder Light on?

How much does it cost to fix the Seat Belt Reminder Light on a GMC Hummer EV?

Will the Seat Belt Reminder Light reset itself on a GMC Hummer EV?
