Recall 20V684 covers 7,516 2020-2021 GMC, Chevrolet, Buick, and Cadillac vehicles with overcured Continental tires. Free inspection and tire replacement at franchised dealers.
GMC is recalling 7,516 2020-2021 Acadia, Traverse, Enclave, XT5, Silverado 1500, and Sierra 1500 vehicles because Continental tires installed at the factory were overcured. The tires can lose air suddenly or shed tread and belt material. Either condition increases the risk of a crash; the dealer repair is free.

What's wrong?
The tires on the 2020-2021 Acadia, Traverse, Enclave, XT5, Silverado 1500, and Sierra 1500 are the only parts of the vehicle touching the road. Each tire carries the vehicle's weight, holds air pressure, and gives the tread a stable contact patch for braking, steering, and acceleration.
The affected Continental tires were overcured during manufacturing. Curing is the heat-and-pressure step that sets the rubber into its final shape. These tires stayed in that process longer than CTA's specifications allowed, which can damage the tire structure before the vehicle ever reaches an owner. GM identified the affected vehicles by matching supplier shipping data, plant records, DOT numbers, and production mold numbers.
There is no warning sign before failure. The tire can look normal from the outside, so the DOT number and production mold number are what decide whether a tire belongs in the recalled group.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
Overcured tires can suffer a sidewall carcass break with sudden air loss, or belt edge separation with partial or full tread and belt loss. Either condition increases crash risk. Drive cautiously and schedule the recall inspection soon. Repair is free at any franchised GMC dealer.
What should I do?
- Check your VIN to confirm your 2020-2021 GMC Acadia, Traverse, Enclave, XT5, Silverado 1500, or Sierra 1500 is included in this recall.
- Contact a franchised GMC dealer to schedule the tire inspection and free replacement of affected Continental tires tied to sudden air loss or tread/belt loss.
- Bring the recall notice if GMC has mailed one. If not, reference recall number 20V684 when you call.
- Drive cautiously until the tire inspection is complete. Pull over safely if a tire loses air or the vehicle vibration changes.
What happens at the repair
At the dealer, a GMC technician inspects the tires for the DOT number and production mold number combinations identified by Continental. Any tire that matches the covered combination is replaced free under recall 20V684. Parts and labor are covered. Out-of-pocket tire repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because all covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior tire repair paperwork.
