What's wrong?
The emergency jack in the 2020-2022 Trailblazer and Encore Gx is the lift tool stored with the vehicle for a roadside tire change. Its job is to raise one corner of the vehicle at the lift point shown in the owner's manual, while keeping the vehicle's weight centered over the jack.
On affected vehicles, the jack can fracture if it is placed on the wrong part of the frame or set at the wrong angle. That off-center load puts force through the jack in a way it was not built to handle. If the jack breaks while the vehicle is lifted, the vehicle can drop during use.
There is no warning sign before failure. The problem is tied to jack position under load, so the jack can look normal before it fractures.
Who's affected?

What's the safety risk?
A fractured jack can let the vehicle collapse while it is being lifted, increasing the risk of injury to anyone near or under it. Do not rely on the recalled jack for tire changes or service work. Use a safe lift or call roadside assistance until the jack is replaced. Repair is free at any franchised Chevrolet dealer.
What should I do?
- Check your VIN to confirm your 2020-2022 Chevrolet Trailblazer or Encore Gx is included in this recall.
- Contact a franchised Chevrolet dealer to schedule the free jack replacement that fixes the fracture risk while the vehicle is lifted.
- Bring the recall notice if Chevrolet has mailed one. If not, reference recall number 21V440 when you call.
- Avoid using the emergency jack until the replacement is complete; use roadside assistance or proper shop equipment for a flat tire.
