2011 Jeep Compass suspension problems

My wife and I just exited the highway where we were traveling 70 MPH (rt 75 south tennessee). We came to a stop light that was red and applied the brakes. We heard a load sound from the right front wheel and the wheel pulled from my hands. I exited the car to find the lower a frame had broken off the sub frame. If this happened on the highway or on the exit ramp, we would have lost control and crashed.

Tl* the contact owns a 2000 chevrolet astro. The contact stated that while driving 3 MPH, the front driver's side lower control arm and ball joint fractured with no warning. The vehicle was towed to an independent mechanic where the vehicle was repaired. The contact stated that approximately a year later the front passenger side lower control arm and ball joint fractured. The vehicle was towed to an independent mechanic and repaired. The contact stated that recently while driving, an abnormal noise was heard.
