    2016 RAM 1500 with 50000.0 miles

    Code P26AB. Coolant 3-way valve is malfunctioning. Currently have 50,000 miles on the vehicle. There is currently a recall for the 2013-2016 Ram 1500 for the same issue but for some reason, the recall don't cover my car even though it's a 2016. Why don't the recall cover my car?

    2015 RAM 1500 with 75000.0 miles

    I bought my 2015 Ram 1500 on november 27, 2017. The truck looked as though it had been very well maintained and taken care of. The first or second week in december a check engine light came on as i was pulling in my neighborhood. It turned out to be a fuel pump sensor which the dealership replaced. Now after a month and a half later, another check engine light has came on while parking at a restaurant. 3 codes have shown up for this cel. They are P26AB, P26A7, and P2681. These codes have something to do with the engine coolant bypass valve control. After only an hour of sitting in my driveway the following day there was a huge rainbow colored leak on the asphalt and fluid settling and dripping from the bottom of the transmission. I have taken very good care of this truck since i purchased it. It is just as clean as the day i took it off the lot. I am worried that there is something seriously wrong with this truck now and that the dealership will try and take advantage of me and the fact that the warranty was only for 30 days because when i purchased it the vehicle was used and had 72000 miles on it. This is my first dodge Ram truck i have ever owned and so far i am very disappointed in the reliability. I will be taking it to the dealership one day this week when i can get off of work. Hopefully they don't try to "pull one over" on me. Attached is the leak in my driveway after an hour of being parked.

    2014 RAM 1500 with 67708.0 miles

    Bought truck as a cpo in may 2015, a month into ownership engine light came on, code P26AB, engine coolant bypass valve. Called the dealership and they were able to get me into a local dealership to check it out. Tech said they did not find anything, it must be an old code they did not erase. Then on 3/4/19 same code returned, P26AB. There has been a recall on 2013 Ram for the same problem.
