Driveshaft problems of the 2015 Chrysler 200

First, there is the hvac/windshield defrost. My concern with that condition is that my vehicle is my main source of travel and to have the hvac to work properly in the summer is vital as well, as having a clear windshield. A breakdown at night, an accident, hitting a pole hole, something or someone would be far worse than a mere inconvenience. Incidentally, my intended use of the vehicle was made quite clear to the sales staff when I bought it. Second, and the matter of far greater concern to me is the transmission. Car making clucking noise, vibrating, jerking while shifting gears and launching while driving as if someone hit me from the back. Third, vehicle is only 2 years old and has had to have the drive shaft replaced. Which in return I've been without vehicle for more then 14 days and occur extra expenses of car rentals, tires and wheel alignment due to irregular wear. Fourth, hesitation on attempt to accelerate. I was informed that issue would be resolved with replacement of drive shaft. Defective drive shaft was the reason for delay and jerking. Fifth, excessive gas burning. I was informed that exist because of drive shaft. Once drive shaft was replaced it didn't resolve issue. I was giving a formula to calculate gas mileage, which was given to dealer. Car averaging 16mpg. Per car sticker fuel economy: highway 29/ city 18. Car is driven mostly on highway without a lot of stop and go traffic.

While driving the drive shaft came out causing the entire wheel to disconnect and subsequently causing the frame to collapse onto the tire of the front passenger side of the vehicle. I had this car for 2 weeks and had it towed to the dealership (tate Dodge) where I purchased it and it is still there since the incident on August 1st because I will not drive it as I do not feel safe in it.
