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.
