Mohawk Auto Sales Sueing me for $12+ dollars after they sold me a lemon while I was 6 months Pregnant!!! Schenectady New York

I went to Mohawk Auto in 2013 for a new vehicle with a small downpayment for it.  I was 6 months pregnant with my son at the time and asked for a van or bigger vehicle.  I received a Mazda MPV that 2-3 months later had Engline lights and brake lights on.  When I called to schedule an appointment for repairs, I was told they were busy that week, I needed to call back.  This happened for a couple weeks.  When I finally got the van looked at a month later, the auto repair dept said they had to speak to someone and they would call me back.  They never called me back and about a week later the van wouldn't start at all so it sat in my driveway.  When I went into labor, i had no time obviously to run and pay them for that week so they continued to harass me while I was in labor, even though my boyfriend told two different people that called that I was in labor.  About a month later, I received a phone call at work asking me about said van(Mohawk auto), and I told them its broken down in my driveway, so they said they will come and take it.  They have terrible customer service skills and allowed me to drive around in a van in which dangered the welfare of my children!  They sued me for $8,000+ in April of 2015, discontinued action against me after I sent numerous letters to them and then re-sued me in December of 2015 for $12,000+.  I dont believe I should be held responsible for a vehicle that CLEARLY was a lemon and they just want to get money from me.  I currently have two kids(plus 2 step-children) and cannot afford to pay them.  Right now they are garnishing my wages and it is only going to make people like me(middle class) have to struggle day to day because of terrible companies like this!!!  I would love to take action against them, but I am not sure where to start. 

I am hoping that by making this complaint they wont get to take advantage of anyone else, especially pregnant with kids, BECAUSE ITS COMPANIES LIKE THIS THAT SHOULD GET SHUTDOWN FOR TERRIBLE ETHICS!!!
