“So we bought the car. In 2012 or 2013. And in 2014 we received a yellow letter in the mail saying that our car needed to be serviced for a recall. We set it up. Ended up taking it in To be serviced for the recalls. Not knowing in 2008 they recalled what is now going wrong in the car, I didn’t say anything at the time we repaired it. It they didn’t either I believe and even if we didn’t say anything they honestly should’ve just repaired the part that was messed up for us and then let us know: now we have spent so much money towing our car back to our house so that it is safe, and have missed appointments, been stranded, I mean we have really, honestly and truly, very very compromised but this issue with the electrical system Our car is having all the time since this recall repair was administered: NOW IT HAS JUST GOTTEN SO BAD WE CAN NOYT EVEN DRIVE IT. We will get stuck where ever we turn it off unfortunately. I’ve not looked online at information taken all the necessary needs to find out if my vehicle was given the recall before we owned it just to be sure too, it was not. I know that everything that I have read relates directly perfectly to Every single issue…”
