Equipment problem

"takata recall" while dealer has told me air bag was completed, it was sold to me with an open entry or questionable completion. Upon driving the car I found it felt shaky & was told they would fix any problems however now that I have taken it in twice and it has stayed there over a week, and then taken home (without my approval) by service manager, when I still complained that it doesn't feel so stable and maybe we should call off the deal or trade for another car, I was told. . "deal is done, the car is yours, we've spent $$ to fix things". My response was "whatever items done were items that should have been done pre-sale and were agreed to be done". The axle ended up being bad and something still feels like the car staggers however I got tired of complaining. I'm not entirely sure that I'm driving a safe car and that it was not in an accident. Not sure what to do as now I owe a loan & have been driving car. My main concern has always been safety. I brought all this to the table pre purchase. I brought car in again because it was shaky, struggling & staggering to go up hill, would not properly accelerate, and was having a burnt smell. What they found was bad axle and something with rotor (which was not caught on first time I brought in that it spent a week there). Car fax did not indicate accident but drivability seems questionable. I bought car 12/31/17, brought back in first week to complete the open items (one being the air bag issue) I brought all concerns up pre-purchase w/agreement they would take care of all. I brought it in & it remained about a week. Picked up 01/13/18. Had to bring in again 01/30/18 due to staggering & burnt smell. Picked up 2/02/18 & when I brought up that I think we should just trade car as I felt maybe I got burned, they said: car is yours, you bought it (in a nutshell). I have all emails of concerns brought up. Just want to be sure.
