What's wrong?
The front seat is bolted to brackets that anchor it to the vehicle floor. Those attachment bolts keep the seat fixed in place when the SUV brakes, turns, or hits uneven pavement. On the 2021 Yukon Xl, Yukon, Tahoe, and Suburban, the seat and its bolts are part of the occupant restraint setup because the seat must stay where it was designed to sit.
The problem traces to assembly-line repairs that required removal of one or both front seats. After the repair work was finished, the front seat attachment bolts were not properly reinstalled or tightened on some GMC recall vehicles. A loose or missing bolt lets the seat bracket move instead of holding firm.
The warning sign is seat movement during braking. Occupants can feel the front seat shift when the vehicle slows, which means the seat is not anchored as designed.

What's the safety risk?
If a front seat has loose or missing attachment bolts, the seat can move during a crash and increase injury risk for the seated occupant. If the seat shifts during braking, stop using that seat and schedule the inspection soon. Repair is free at any franchised GMC dealer.
What should I do?
- Check your VIN to confirm your 2021 Yukon Xl, Yukon, Tahoe, or Suburban is included in this recall.
- Contact a franchised GMC dealer to schedule the free front-seat attachment-bolt inspection and installation that secures the seat to the vehicle structure.
- Bring the recall notice if you have it. If not, reference recall number 20V735 when you call.
- Use the vehicle with care until the repair is complete, since a loose front seat can move during a crash and raise injury risk for the seated occupant.
What happens at the repair
At the dealer, a GMC technician inspects the attachment points for both front seats. If the seat attachment bolts were not reinstalled correctly after assembly repair work, the technician installs the needed bolts. Parts and labor are free under recall 20V735. Reimbursement is not handled through a separate program because all covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior seat attachment repair paperwork.
