NHTSA Complaint #11508035 — 2019 RAM 2500

We bought our truck in November 22, 2022, used certified pre-owned with 22135 miles, On 12/27/2022 message code came on water in fuel tank. 12/29/2022 dealership service helped us to drain fuel filters and cleared the code. 12/30/2022 same code came back. 1/8/2023. Truck broke down with a major total fuel system damaged. Parts were ordered, but repairs did not start yet. Everyone is trying to say it is a user error. We refilled DEF liquid correctly after which the gage showed was almost full. Dealership was blaming bad diesel was used, but as a consumer how in the world will i know which brand or company: they all are governed to sell proper diesel. We only drove about 3000 miles. There's no way possible for such to happen. Dealership told us ok to drive and keep refilling fresh diesel. We learned that there was already a recall for fuel system back in September of 2022. Supposedly if diligently and correctly it was taken care of, this same problem should have not come back at least for the next 10000+ miles. We only put on about 3000 miles from the date of purchase. Also according to inspection of dealership and service history, they also replaced fuel filters in October of 2022. Truck broke down even before our first payment was to be due. Currently our truck is not drivable and we are in 7 yrs loan. Absolutely ridiculous. There must of been a hidden tank leak that caused fuel contamination. Dealership where our truck is confirmed DEF liquid was mixed with diesel gas and a corrosion around some parts. Please help us! This is a nightmare. Thank you so much in advance!
