Axle Shaft problems of the 2014 Jeep Cherokee

A couple days after purchasing the vehicle, was rounding a turn, going uphill, and accelerated. At that point, the car wobbled violently. Upon arriving home, I checked the tire pressure and found all to be around 48#. Since the tires had been inflated with nitrogen at the dealer I went there and was told by the service department that the over-inflation was most likely the cause. The "tire technician" took a few pounds out of each tire and pretty much said if the trouble light is not lit, the pressures are fine. When I got home, I checked the pressures and compared with the tpms display. None of the tires had the same pressure and all over 40#. I adjusted the pressures of the tires to the pressure stated on the tire sticker on the door jamb. I continued to experience a wobbling and the service department said there are no known issues. I agreed to document when this is happening and under which conditions. I experienced intermittent, but frequent wobbling upon acceleration between 10 and 20 mph usually in second gear. On Nov 2, the dealer confirmed the wobbling and stated that Jeep does not have a fix at this time. They have a problem where the front axles do not have enough slop to take left/right movements of engine and bottoms out on axle shafts. Should be February. When I checked in March, I was told Jeep revised date to be 3q 2015. Sep 29, I was now told 4q 2015. I then contacted fca customer service to go beyond the dealer find out facts from the manufacturer. The rep said that she would contact the dealer for their input while I held on the phone. She got back on the phone and simply said that there is no eta for the fix and to continue checking back with the dealer or go to another dealer and see if they can find something else wrong. No fix after all this time, that's terrible. The fca rep mishandling my concern, in my opinion is as bad.
