2015 Ram 2500: check engine light

Filed Jul 25, 2025 · Brakes, Electrical · OK

While driving down highway 65 mph, abs system activated causing right rear brakes to activate causing vehicle to activate steering control making truck head towards on coming traffic before able to control vehicle to shoulder of roadway. Would like to know if, when, and who and where any previous recall work has been performed to this vehicle, bought at a dealership in Oklahoma with check engine light on, told it was gas cap. Turns out it was not a gas cap, there was programming involved to remove the MIL function of brake system. ECM was sent to a 3rd party vendor and unlocked, afterwards the previous program was unlocked showing disabling of MIL functions for several functions. Vehicle is having issues with electrical radiator fan causing excessive heat in compartment, what was the fix for this by MFG? Was it to just program out the electric fan from coming on at high speed ? Now engine within 20 minutes of idling overheats truck( road construction/wrecks)

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.

My 2015 truck has 89,000 miles. The emission system DPF was replaced under EPA settlement with RAM at about 20,000miles. The DEF system failed at 89k. When it failed the truck started bellowing toxic ammonia from the exhaust. When the system failed, a check engine light came on and the truck indicated I had 150 miles before 5 MPH line mode. The amonia Fumes where overwhelming. You could see the cloud coming out of the exhaust. The dealer confirmed the DEF pump failed. However the pump is still working and pumped half a tank of DEF into my exhaust system in less than 30 miles. Independant shop suspects additional damage to NOX sensor and other parts as a result of the pump failure. Ram admits the pump is a high fail item but not covered past original 80k emissions warrenty. The pump is 1,400 dealer list. I have never heard of a vehicle having less than 100,000 10 year emissions warrenty. My VW TDI passat has over 150k full emissions warrenty from the EPA settlement. I don't understand how RAM is not liable for low milage emission failured below 100k miles. The pumps fail alot! Apparently they have been or are trying to redesign them. This is one leading reason why owners delete unreliable emission designs. I would like my emissions failure covered by RAM and the software logic updated on all RAMs to shut down DEF pumps when they fail so they do not produce heavy toxic ammonia clouds.
