2 Engine Exhaust System problem

Failure Date: 07/18/2019

At 60mph on the freeway, my 2018 Mustang gt with 2,000 miles on it blew the engine. Massive amounts of smoke were pouring out the exhaust pipes and from under the hood and the vehicle was violently shaking and sounder like a tin can full of nuts and bolts. Got the car to the shoulder but my wife and I were scared to death as cars were whizzing by just inches away. According to online chat rooms a number of these engines are experiencing similar failures. A bad batch was produced and Ford should have recalled them. I asked Ford to replace the car with a factory intact vehicle and they denied the request. They say all that is required of them is to fix the issue. I bought the car as a collectors item and this takes away all value as a collectors car. I offered to split the cost of getting a new one and they said no. I have suffered monetary damage on the value. It's a dangerous situation having these engines blow up. I feel fortunate to have made it through the ordeal on the freeway and its aftermath. The back wheels could easily have locked up and that would have been catastrophic.
