Business ProfileforBloomington/Normal Auto Mall

I am writing because I believe the dealership has violated the Illinois 15 day or 500 miles law for a used car. On March 15, 24, I purchased a 2017 Chevy Traverse from Bloomington Normal Automall. The salesman I dealt with's name is *** *. I left the car lot and got about 10 miles from my home in ********* *******, Illinois and the car started violently shaking between gears. When I got home I immediately text the salesman who told me to bring it back the next day on March 16, 2024, which I did. After a few days I was told that the car would need a rear suspension, shocks and new tires. After several texts back and forth between myself and *** *, I was told on April 2, 24 the car was fixed and ready for pick up. I went to pick it up, again, the car ran fine on the test drive. I left the dealership and again, 10-15 miles from my home the car starts shaking violently between gears. So, I realized it must need to be warmed up to a certain temperature before the issues happen. Again, I text *** *. who was off the day I text. So, I left 3 messages for the general manager, I never and still haven't received any responses from the manager. The salesman says there's nothing else that can be done. I told him the car needs driven and warmed up. No response now from the salesman either. I'm being ignored. I expressed several times I am extremely apprehensive with anything their auto repair department says as I was told the only problem when I bought the car was a tire sensor needed reprogrammed. Now, the suspension, tires and shocks need changed as well. I asked for paperwork and receipts showing what work was done, I was told there was no paper work because "they did the work themselves", which is another issue I find very odd. The dealership kept my car long enough to be right outside the 15 day law. The salesman says he would ask his manager if they could "trade me out" into a new car. I am extremely apprehensive because of all this.
