Engine Rattling And Whining Sounds problems of the 2008 Saturn Outlook

Bought from sterling motors in watertown sd, in 2017. Trade in was 2000, plus 500 dollars cash, for a 2008 Saturn Outlook xr awd. Loan was for 10000 after the 2500 trade/payment. Had 160000 miles now has 180000. Within less of a week check engine light comes on, stabilitrac, service air bag, timing chain, traction control all came on. As of 2018 we have replaced all four tires, brakes. Struts, rotors, tie rods, battery, co2 sensor, thermostat, and a few other things. It still needs power steering pump, timing chain fix, cv joints replaced and who knows what else. I've complained to the dealer and he told me I can not trade back, and when we bought it he said it passed the suspection test and claimed nothing was wrong with it. He had to top of the power steering fluid as it was whining and low, said that it was because they flushed it. So now upon turning it has this weird rubbing vibration and loud sound, it shakes at all speeds, it loses power while driving stutters at low speeds, passenger window button don't work, loud noises when idling, whining noise from power steering either just from stationary or driving. It takes forever to pass someone as it almost stalls with the gas pedal all the way to the floor. It has a weird chemical smell when using heater. This Saturn Outlook is unreliable, very unsafe even after fixing what I had already fixed. I have an invoice for the repairs from watertown Ford dealership in south dakota. Sterling motors will not help, said they could fix but I have to pay for parts and work. He sold me a lemon and he doesn't care about the safety or wellbeing of me, my children or others on the road. Talk to the loan place and all they said is I have an agreement to pay regardless if the car works or not. I'm currently 2 months behind. I can't afford another 700-3000 fix while paying 300 a month for a SUV that is unsafe to drive.
