2020 Chevrolet Colorado Brakes Problems

Vacuum pump seized, causing loss of power assist on brakes. This happened as I was approaching an intersection to make a right-hand turn. When I press down on the brake pedal it felt hard, like it was locked up. After pressing down on it with both feet, I was able to slow the vehicle down enough to turn out of the intersection. If this event happened when there was another vehicle in the intersection or approaching the intersection on the side street that I was turning onto, it would have led to a collision. Not being able to slow down adequately, I had to swing wide in the turn. This incident happened at a relatively slow speed. If it had happened at highway speeds it could have been catastrophic. There was no warning light prior to the incident the check engine light did not come on until after the incident. The Pump seizure caused the connecting coupling between the exhaust cam and pump to shatter. The damage was extended to the exhaust cam and valve cover and leaving metal fragments in the engine. The local Chevrolet dealer has given me an estimate for the repair of over $2400

Driving on the highway speed limit 65-70 my truck started decelerating and breaks got hard and could not use break. Had to get home using emergency petal break and drive. My truck is only 2020 model for this type of problem. Want to see if I can get this fixed with the manufacture defect warranty. Took my truck to a Chevy dealer and they are saying it can be a faulty vacuum pump.
