That's exactly what I worry about. I don't dispute whatsoever that the product will help the issue I'm having. An as long as everything is functioning properly , no problem, but when codes start popping up like brutal said, I would have to believe that fca could say it was caused by such and such after mkt product. Wich is what I don't want to do is get into a back and forth over warranty claims. I'm sure you can fight it and more than likely win but I don't want or need that stress to deal with. I'm sure there is nothing out there that's a 100% guarantee, unless mopar makes a product. You would think ram would correct this issue from the ground up if its just that easy of a fix with out any repercussions. An that's what makes me wonder, what does fca know that they don't just correct the issue as easily as this device does.
