Suspension Noise problems of the 2006 Mazda MAZDA3

I was on a freeway off-ramp at approximately 50 mph, when loud grinding and crashing noises came from under the hood. The car then became difficult to steer, and would no longer propel itself. I coasted into a driveway near the bottom of the off-ramp. Upon inspection, I discovered that the transmission "motor mount" had broken. The engine apparently lunged forward, sheering off bolts to the other motor mounts, and landed on the suspension, severely damaging many front-end parts. The car was towed to the nearest Mazda dealership, whose service department confirmed my assessment of what had occurred. The repair estimate is approximately $3,000. Before the incident, the car was in excellent condition, having been well-maintained. (I have service records. ) I discovered that Mazda had recalled a number of Mazda 3's for motor mount problems, but my car was not among those recalled. While the car is no longer under warranty, this is a very unusual type of failure, which, under other circumstances, could have caused a serious collision. I have owned numerous cars over the years, with far more miles on them, and never had a motor mount fail in such a catastrophic manner. This seems like a design/engineering flaw.
