Well first problem was in sept 2014 mileage on car was 54170 the car had to be towed from my job to dealer came out after working and entire electric system was down could not start or open locks on car with key system at that time they told me the timing chain broke to which they fixed and on receipt they claim they replaced chain gasket and sealant also they claimed they performed a carbon cleaning and did a 27 point inspection now at mileage of 73740 they claim the motor is bad and said it would not last and wanted to charge me 7500. 00 for a new motor when I told them the check engine light came on and would not go out I was told because I went to another place for oil change that was a firestone place the mechanic claimed the actuators were clogged and claimed the motor was not repairable at that I decided to trade the car in and I did lease another car at the same dealer I know its not their fault the engine did not hold up like it was thought to when I purchased it. While I was waiting for reasons why the light was on spoke to another person and she claimed she had 2 persons who had similar issues so that is why im looking to see if there is a suit in progress.
