Differential Unit Problems of Mazda CX9

My vehicle seemed as if the transmission was slipping between gears on the highway it would take forever to switch into higher gears for higher speeds then when slowing down it would jerk and then finally stop or if I was in traffic where I didn't need to make a complete stop it would jerk to slow down and skip gears and jerk to speed back up while on the high way traveling at normal speed with cruise control set it went from 6th gear to 4th gear for no reason at all! then it started making noises sounding like both the front and back end first you would only hear them when turning right or left then started hearing them in reverse then you heard them while driving all the time on the highway back roads and parking sounded as if my tires were going to fall off! I contacted carmax because that's where I purchased the car in March of 2017 it's now agust 2017 and told them what was happening they lied from the initial phone call but that's besides the point they had my vehicle for a week saying they were looking at it thoroughly to make sure what they found in the rear differential was the issue they assured me it was told me if I heard the noise bring it back ASAP as I was driving the vehicle home it was still experiencing the same issues we tried to call them immediately but they were closed we called them that Monday and couldn't get anybody on the phone so we left a message we continue to call them for two weeks before they finally gave us an appointment to bring the car and I could not drive my car for the two weeks that I had it in my possession because I was told through my extended warrantee that driving my vehicle while it was still damaged would void my warranty the day after we drop my car off back at carmax I was called and told that the date it was pulled out of the garage on the original repair date 3 weeks prior that the tech noted to bring to Mazda.

I have maintained my 2009 Mazda Cx9 to date and only have 48,000 miles. I started hearing a weird noise in the front wheel (humming) it got progressively worse . Now my mechanic tells me that the differential is going. This has to be a manufacturers defect due to the low mileage and the upkeep of this vehicle. Assistance with this would be greatly appreciated. In addition, I've looked online and see that other owners are experiencing the same issue.
