After shutting off vehicle, the cooling fans would engage. They would continue to run for 15-20 mins regardless of engine temp or run time. This was the first indication that something was wrong. Shortly after that the car would not start due to lack of power from battery. I had a diagnostic check run on system that showed that most parts of the electrical system had some type of error or another. I replaced the battery due to a bad cell and re-ran diagnostic. Shows that the computer was not operating correctly which was tripping the rest of the error messages. Would this be a factory defect for the computer?

A few months ago I started to smell fuel after I parked my car and noticed a leak in the lines. The lines were indeed rusted out and I had them replaced. Now a few days ago I noticed it again but this time it was coming from the fuel tank. I saw that there was a recall for this problem, however I am not in one of the states that it was issued in. This is a big problem and I have seen a lot of people online complaining about this issue and the recall should be nationwide as it is a rather large safety concern.
