Front Suspension Control Arm problems of the 2013 Jeep Wrangler

Purchased vehicle used in may 2015. I'm the second owner. On approximately Aug. 29, while driving and making a left turn from a stop, I heard a banging noise. The same banging noise happened about 1 week later (Sep. 3), but this time when turning right from a stop. I drove vehicle home and inspected under the vehicle to check it out. I discovered that the upper control arms on both the driver rear and passenger rear sides are completely broken into. Vehicle is still under 3 year 36/000 factory warranty and I also purchased an extended warranty. The dealer provided a "recall report" which came back clean. My vehicle has been parked since Sep 3. I am having it towed to a Chrysler dealership in a couple of days after parts come in for repair. This vehicle could have come totally apart had I been driving at a high rate of speed.
