Our 2012 RAM 2500 truck with 135k miles, had it's fuel tank fail. The dealership in Oak Ridge, TN tested the vehicle and found that the gas tank tubes were broken causing us to not be able to fill the tank. The dealership recommended "NEED TO REPLACE GAS TANK". Mopar aka Stellantis does not make the fuel tank anymore, the "replacement" fuel tank does not work (completely wrong configuration), there is not an aftermarket tank. We have a Million Mile bumper to bumper warranty with MOPAR. "Customer Care" does not care.

Prior to epa emissions recall I would achieve diesel fuel efficiencies as high as 21 mpg highway, pulling a 18 foot trailer at a 1 hour duration. The city mpg averaged to 13-15 mpg, since the emissions recall update made on this vehicle, mpg has averaged between 10-13 mpg on highway with no load/no trailer and averages between 9-11 mpg in city. These benchmarks have been consistently compared and road conditions have been same. To add to this issue, there has been a loss of power that has caused unexpected hesitation in a number of instances. Several times I was put in harms way as crossing city divided highway, crossing streets and/or dividing highways where that multi-directional traffic lights are not always present. To further explain, realizing the power pickup was not present and turbo did not seem to be 'spun up' even though acceleration was increased dramatically. Note, to help to possibly remediate these potential accident occurrences, I must power brake and increase engine RPM's to help bring the vehicle to a power level to reduce the risk of power latency. This sometimes helps but not always because power impotency seems to be unpredictable at times.

When accelarating, from a stop especially, the throttle intermitantly will give an almost dead response. It can be pressed all of the way down to wide open and it slowely developes power and does not reach full power untill after the 1, 2 shift. It is dangerous and is going to cause an accident. No mil light nor troible codes are present.
I have two recalls for the fuel heater shorting out and possible fire. I call dodge to get it fixed and they tell me the parts are on back order. If they can't fix my truck I want one that me and my family can drive and feel safe in.
