Chevy, GMC and Cadillac trucks miss brake fluid warning

NHTSA campaign 24V674000 · Reported 2024-09-12 · General Motors, LLC

high How serious is it? About this label

Serious: the notice does not tell owners to stop driving, but with no warning light your braking could get worse without you knowing, so get the update quickly.

What's wrong, in plain English

Your truck or SUV has a computer that watches the brake system. Because of a software problem, that computer may not turn on the dashboard warning light when brake fluid gets low. You could keep driving without knowing anything is wrong, and low fluid can make the brakes work less well. The fix is new software, sent to your vehicle over the air or installed by a dealer.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to confirm your vehicle is included (GM's recall number is N242447990).
2. Watch for the over-the-air software update, or call Chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, or Cadillac at 1-800-458-8006 to set up a dealer visit.
3. Have the dealer install the update. The repair is free.
