On December 14th, I was driving my 2017 Ram 3500 with 95,000 miles down the road when I encountered a tree completely blocking the roadway. When I applied the brakes I heard a pop and the brake pedal went the the floor. At this point I had no brakes and was forced to hit the tree. Thankfully it was in a rural area and no one was killed because of the failure. My safety was defiantly put at risk because of this failure. Once stopped I was able to look under the hood and found the top bolt that holds the brake master cylinder to the firewall sheared completely off. This caused the brake master cylinder to fall away from the firewall and disabled all braking functions. I had the vehicle towed to a Ram Dealer and then contacted Ram (Stellantis) for a reason and solution to fix the failure. They sent an engineering analysis associate to look at the the truck finally on the January 9th. They then sent a very generic letter on the 12th stating that they don't believe it is a manufacturing issue. They will give the dealer or myself no further information on what they found, what the cause was, or how the dealer should proceed to fix the problem. The vehicle is still currently sitting at the Ram Dealer and has not been fixed if you would like to inspect it. There were no warning lights, messages, or prior problems associated with this failure. It was a sudden and catastrophic failure of the braking system.
