My 2020 does this. It is the brake assist I wish I could disable the feature. But whatever
Goo my wife thought i was nuts and the lame excuses the dealers gave me was ridiculous answers. "The car is so heavy that they added this feature." I told him to show me in writing where this is stated, he said he was going to call GM headquarter to get the answer. Never hear back, go figure. But thank you very much for your time and by the way this is not good for the over all MPG so it doesn't make any sense. JMO
