Chevrolet Tahoe and GMC Yukon brakes calibrated incorrectly

NHTSA campaign 21V579000 · Reported 2021-07-29 · General Motors, LLC

high How serious is it? About this label

Reduced braking performance increases the risk of a crash, especially when towing; the notice does not tell you to stop driving, but get the free recalibration soon and be extra careful towing until then.

What's wrong, in plain English

When these SUVs were serviced, a dealer technician may have set up the brake system with the wrong settings. That can affect several things that depend on the brakes: the system that keeps the vehicle from sliding sideways, the traction control, the anti-lock brakes, and how the vehicle brakes when you are towing a trailer. Overall, the brakes may not perform the way they should. A dealer will recalibrate the brake system control module to set it right.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your Tahoe or Yukon is affected.
2. Call Chevrolet at 1-800-222-1202 or GMC at 1-800-462-8782, recall number N212340970.
3. Bring the vehicle in for the brake recalibration — it is free of charge.
