NHTSA Complaint #11462760 — 2012 FIAT 500

I bought this car about a year ago, ever since I got the car the first issue started within a month it just started to shut off for no reason first at a traffic light, afterward while I was driving called the dealership who sold me the car I was told to bring it to find out they did not have a certified Fiat Mechanic that would be able to look at the car so it was towed to another dealership. I was told they fixed the issue but once again the vehicle started doing the same thing even more frequently fast forward my car has yet to be fixed I feel like I am going to get rear-ended and hurt really bad and all I get from the dealership is that they can't fix it. My question to them is why I sell me a car that you knew you could not repair or you knew you really didn't check properly as per your words you don't have a certified mechanic.
