## What is wrong

General Motors LLC \(GM\) is recalling certain 2018 Cadillac Escalade, Chevrolet Silverado 1500 and Tahoe, GMC Sierra 1500 and Yukon vehicles equipped with either a 5.3L or 6.2L V8 engine.  The output of the mechanical vacuum pump can decrease over time, decreasing the amount of vacuum/power brake assist.


## What can happen

A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash.


## The remedy

GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge.  The recall began November 11, 2020.  Owners may contact GM customer service at 1\-866\-522\-9559, Cadillac customer service at 1\-800\-458\-8006 or Chevrolet customer service at 1\-800\-630\-2438.
