Bought a 2020 Silverado Custom TrailBoss 2 weeks ago. The second day of owning the vehicle, I cranked the truck and had no power steering. Took it to the dealership and they could not duplicate... less than a week later I had the same Electronic Brake Assist Failure message appear at 279 miles. Had to put my full weight on the brake pedal to stop. The dealership is replacing the master cylinder. This is unbelievable.....
