I bought a Nissan Altima from Capital Toyota in September of 2019. In February, 2020 the transmission started acting up. The dealership kept it for a week & a half & refused to fix it. Now on Friday, March 27th the transmission is completely out & inoperable, leaving us without a car. I am unable to get another loan due to not being able to trade this one in & because it is a new loan & I am upside down on it. There is a class action lawsuits on Nissan Altima between 2013 & 2016 & I'm sure the dealership was aware of this issue. They have made my credit even worse because I cannot pay for a car when I have no way to work to pay for it, much less pay for a car that doesn't run & is stranded on the side of the highway.
