Chevrolet Traverse, Buick Enclave airbags may not deploy properly

NHTSA campaign 21V472000 · Reported 2021-06-24 · General Motors, LLC

high How serious is it? About this label

Air bags that do not deploy as intended can increase the risk of injury. The notice does not tell owners to stop driving.

What's wrong, in plain English

While these SUVs were in for service at a dealer, some of them had the wrong software loaded into the system that controls the front airbags. That software decides how the airbags fire in a front-end crash. With the wrong version in place, the front airbags may not go off the way they are supposed to in a crash. There is no warning light or symptom; a dealer loads the correct software.

What you should do

1. Look up your VIN at nhtsa.gov/recalls to confirm your vehicle is part of recall N212340220.
2. Call your Chevrolet dealer (1-800-222-1020) or Buick dealer (1-800-521-7300) for an appointment.
3. Have the airbag software updated — the update is free.
