Brakes Failed problems of the 2020 Chevrolet Traverse

Brake failure on a 2 day old chevy Traverse sequence of events . . . 1. I purchased a Chevrolet Traverse from lawrence Chevrolet on Tuesday, January 14, 2020 and took delivery at about 5:00pm. 2. While my wife was driving on Thursday, January 16, 2020, we experienced a low speed brake failure. This occurred while on the way to dulles airport at about 6:00pm. The brakes were slowly applied and they did not respond. The brakes were then pressed hard and they did not respond. I (mike) reached over to try shifting the car into park but was unsuccessful and the car drifted at a very low speed, �a walking speed,� and into the back of a tractor trailer. We had very ample space to stop however the brakes simply did not respond. Minimal damage occurred to the vehicle's front. I immediately checked to see if something was in the way of the brakes pedal (a floor mat or other obstruction) and there was no obstruction. I could see, and I am certain, that heather had her foot on the brake pedal. 3. Glenda (onstar/gm) established case number 9-5760767809 and set up a tow to ourisman Chevrolet of rockville, MD. 4. I was greeted by roberto (service manager?) and helped by both roberto and allen krum (assistant service manager). They also took down a description of the incident and they gave me a rental car. Of note, they said that someone outside of the dealership (a gm rep?) would be coming to look over the car.
