Hi, I have a 2014 Ford Taurus Limited. About 6 months ago the check engine light came on, I read the code and it came up with P0430 Catalyst System Efficiency Below Threshold Bank 2. I brought it in they said that I could get it replaced, or to extend to make it last longer. Then a month later it turns back on, I get the Cat replaced, and it was perfect, perfect until 6 months later when it just came back on... and for what? The same exact code. This car is 6 years old, this isn’t something that should be happening TWICE to this car. Has anyone had any thing similar with their Taurus? Or if you haven’t do you know why this would be happening to a car this old? Thank you.
