What's wrong, in plain English

These trucks received a software update for the module that controls the electronic brake system. That software contains an error, and because of it the truck's electronic brake assist may be switched off. As a result, the vehicles do not meet federal requirements for electronic stability control and for light vehicle brake systems. General Motors is recalling certain 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, and dealers will reprogram the module at no charge.
