Chevrolet and GMC trucks, SUVs may lose brake assist

NHTSA campaign 19V645000 · Reported 2019-09-06 · General Motors LLC

high How serious is it? About this label

This is serious because a longer stopping distance can cause a crash, though the change comes on gradually rather than all at once, so drive with extra following distance and get the free reprogramming done soon.

What's wrong, in plain English

The pump that provides the suction your power brakes rely on can get weaker as the miles add up. As it fades, the brake pedal gets harder to push and the vehicle takes longer to stop. The brakes still work, but you have to press much harder. Dealers will reprogram the brake control computer at no charge. Repairs began October 8, 2019, under GM recall number N192268490.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm recall N192268490 covers your truck or SUV.
2. Make a dealer appointment for the free brake control module reprogramming.
3. Call Chevrolet at 1-800-630-2438, GMC at 1-800-462-8782, or Cadillac at 1-800-458-8006 with questions.
