general problems of the 2005 Cadillac SRX

One day after around 2 weeks of buying my car, I started to hear strange noises inside the rear car door panels everytime I lower or raise the windows. One day I was at work about to go to lunch, so I got in my car' turned it on then started to drive away at the same time lowering my windows to air out the hot air build up, then after a minute or so as I was driving I started to roll up the windows' suddenly I heard a loud noise and seen that my rear driver side window not there. . . . I went to a services station where had one of the workers check it out and advised me that the window had just fallen into the door. . . I had them temporarily closed the window and lock it in place until I could get it repaired. . . . A few weeks after that' my rear passenger window did the exact same thing. . . After it was getting rolled up driving down the highway, I had to pull over on the emergency lane to pull the window up and lock it in-place the same way I had the other one done. . I had it check out and an estimate was given but I was advised that this was caused by an manufacture defect.
