general problems of the 2008 Toyota Scion Tc

I have newish wheels and tires. Last year I took my car into les schawb to get an alignment done on my car thinking that is what the problem was. The guy afterwards told me he fixed it as well as he could but wondered if I had hit something in the back and that's all he told me. My steering wheel shakes back and fourth rapidly when I am coming to a stop. My car can not drive straight at all either while I'm on the rode. It will pull to the left so I turn it the opposite way just a tiny bit and it pulls my car the other way very hard and it is very scary and dangerous to drive.

I got on the freeway driving to pick up my mom in the Sunday morning around 6:50 am she works in lax driving on the 110 south freeway in los angeles,CA. This happen between manchester and century . I was in the third lane on the freeway I was going 65 miles per hour motion and I switch lane to the right and my steering wheel lock on me after switching lane my break pedal wasn't working and the steering wasn't responding to the left , the subject vehicle was merging really fast passing 2-1 lanes until I hit the wall and my car flip up-side down rolling for 13 seconds up side down on side the wall. My air bag when off when the car was up side down. I look at the radio and saw white smoke I turn off the car,un buckle my seat belt up-side down, craw out side the passenger window. I got up and took a picture and called the Toyota corporation now um waiting for inspection. For the subject vehicle to be defected well um letting people be aware of this problem on Scion Tc 2008 I o most lost my life. Now I have cut finger skin and left ankle hurts from trying to use the break pedal my elbow has scar fro the window breaking I cover my face crossing my elbows as a shield for my head I had a sweater and long sleeve my it still cut my left elbow. I am the title owner and took me 7 years to pay off this car but now I want my money back or a replace vehicle. I only have liability and I know the insurance wont believe me.
