New to forum. This may be somewhere else. Have a 2019 Silverado 1500 RST Crew Cab. Backing out of gas station brakes went to - felt like 5% power. Luckily nobody behind me. Decided to continue to drive with almost no brakes calculating stopping distances. Turned off for 30 minutes and everything went back to normal.
Anticipate some recalls or software updates with the new braking technology.
