I purchased a 2011 Versa from a dealership about a month and a half ago. Two weeks into have the car, the engine wouldn't turn over. They towed it to a Nissan servicer and I was told the keys needed to be reprogrammed. Got the car back a few days later and the same issue happened. The reprogrammed the keys again and kept the car a little longer testing it out to make sure it started. After a week I got the car back, drove it for a week and the same issue occurred. This time the told me they would replace the nats antenna. They ordered the part, replaced it and tested the car to make sure that it would start. The car was delivered today and when I went to start it to move it from where the tow truck left it, big surprise, the car wouldn't start. They took the car back and said they were opening a claim with Nissan to try to figure out what's going on. When I bought the car I was told it was like new. Even though it was 2011 it only had 18K miles. I checked the carfax, no accidents, no recalls, nothing like this mentioned. I've been googling but can't seem to find anything. What could possibly be the issue here? What questions should I be asking?
