I was in a parking lot and parking at an EV charger. As I attempted the brake, the vehicle did not respond, so I tried to pump the brake and still no response. It eventually made contact with the barrier in front of the charger. It caused some damage to the front end and several lights are lit up on the dash that aren't normally lit. This took place over the course of maybe 2-3 seconds, so minimal time to react to the brakes failing. The vehicle went over 3k miles earlier that day and leased back in Sept 24, so still fairly new. Have tried calling two Chevrolet service departments and there have been either scheduling issues or they say they do not have an EV tech. Contacted Chevrolet about where to take it to be checked out and they are supposed to get back to me.
