The high pressure fuel pump is disintegrating. It has been recalled in newer dodge rams But has not been recalled 4 2015 even though it is very similar and made of the same material. This has been confirmed with the dodge dealership as this is where it sits, so it is available upon request. We had a check engine light come on prior to the incident but was never Indicated when checked at the shop that this was the problem. As far as safety goes you never know when it is going to act up. It usually doesn't have power from the get go or loses power while driving, Putting people's safety at risk as it will slow down to almost stopping or not go at all. It also continually blows black smoke. It has been inspected by the dealership. It has been inspected by an insurance adjuster all confirmed the hype. High pressure fuel pump is the problem and there is shrapnel throughout the entire fuel system.

Def gauge is stuck. I have traveled nearly 3,000 miles and still the gauge has not moved. I was checking on-line and seen where there was a recall on this problem with a prior model.

Deal throttle pedal when making fast accelerations due to rapid changing traffic conditions in city traffic. Pressing throttle, letting off and then pressing throttle again results in no throttle response for 1-2 seconds.

On 6.7L cummins diesel there can be an unpredictably long ( up to 2 second) delay between when the accelerator is pressed and when the truck actually begins to accelerate. This is not turbo lag (which may limit the amount of power until the turbo spools up). This is not a stumble. This is an actual delay in the computer applying fuel to the engine. It is total dead time as if the accelerator was not pressed at all. It happens under the worst of conditions, when you need hard acceleration and need it now. It happens when you attempt to accelerate quickly, especially when you were coasting or had just let off of the pedal. These are conditions that often occur in traffic with many other vehicles nearby. The long delay between throttle application and engine response is extremely dangerous. My truck has the latest "flash" from the dealer, it is running the most up-to-date firmware available from the dealer. Dealer stated that they know about the issue but have no plans to fix the issue.

Fuel is venting from the vapor canistar, this fuel vapor canistar is located right next to the fuel fill hose and is tye-wrap to it.during fueling of diesel product the fuel tank is pressurized and vapor fumes come from this vapor canistar.the diesel vapor is not allowed to vent into the atmosphere so is suppose to be contain here at this canistar.also during fueling of diesel product the tank becomes pressurized as fuel is occupling space forces the vapor up the canistar what is happening I noticed is that fuel also comes out of the vapor canistar and runs down the outside of the diesel fill hose and on to the inside of the lower bed body.no fuel of any kind must come out of any truck, SUV, car during fueling.if you look on the internet you can find other Ram 2500 owners in the 2014 Ram model year experiencing this as well.I have notify Ram customer service and ask that a Ram engineer contact me or someone from Ram that understands this truck, to date no one has called me and that was 2 weeks ago.
