Chrysler customer complaint

I bought a brand new no miles on a 2015 Chrysler 200 limited. 6 months after purchase the starter went out. Then they had a recall on the ignition switch after that was resolved 6 months later starter goes out again. Picked it up from the dealer and I felt my car was not running properly. Called Chrysler headquarters They sent me to a different dealer, well they checked my car out and the cylinders were misfiring fixed that issue then a recall on the transaxle. So, after 50,000 miles they had to replace the engine. Yes that's right the engine. Well the car started to jar going forward and stopping I have complained but, they say awe its a 9 speed transmission its normal. I don't think so when my children complain of whiplash. So, I asked for a substation of collateral. They want me to trade in my care which I'm upside down in and they want the dealer to sell my car to another customer so they can have the same problems I'm having.
