2015 Ram 2500 engine problems

Filed Jul 29, 2026 · Engine · MI

On two separate occasions, once in 2025 and again in July 2026, while pulling a travel trailer an emissions control fault in the EGR system caused the Cummins turbo diesel engine in the truck to lose power. At this reduced power, highway speeds could not be maintained, and even small hills were difficult to climb. This is a significant safety problem, and the dealerships could not provide a timely repair due to lack of parts availability. The manufacturer of software in the engine control system does not allow the use of aftermarket parts. This is monopolistic and anti-competitive. An emissions control fault Code should not deprive me of the use of my vehicle.

Mopar has discontinued parts for many Ram vehicles with a 6.4L Hemi motor including the exhaust manifolds. My exhaust manifold is currently cracked and has an audible leak. Exhaust enters the cab of the vehicle when starting, idling, or reversing. They have no indication of providing a fix for this and the parts are not available aftermarket either. This broken piece not only affects the performance and safety but renders my truck unusable per DOT guidelines and would be red flagged during a roadside DOT check. In my area I know of three other trucks with the same issue. I have tried to reach out to the manufacturer with no response and all the dealers I have tried to reach do not have a solution. This problem can affect trucks as new as 2019 and old as 2011.

This vehicle has a manufacturers #X99 extended warranty. It is for the Turbo Actuator. It extends to 15 years or 150,000 miles. I had a failure of my Turbo Actuator. The vehicle went into limp mode approx 2,000 miles from my home.The malfunction indicator lamp went on and I had to get the control solenoid fixed in order to continue to use the vehicle. We were told that this was related to the Turbo Actuator and to get it fixed when we got back home. I had to have more work done on it once home to finish the Turbo work done.I have approached Ram through mail and email to get reimbursed for the costs. I am continuously getting denied from the manufacturer. When I get emails from Stellantis the people only have one name and no direct contact number so I can speak with them. I have continuously asked to speak to a supervisor and no on will get back to me. I have submitted all my costs to have this fixed as well as the extended warranty X99. I have provided all the information they ask for per the extended warranty. I cannot speak to anyone about why they say my vehicles is not covered. According to the extended warranty X99 it is covered as my vehicle has approx. 93,000 miles at this time.

Turbo Actuator for Ram 2500 has been recalled in 2022, but for some reason, my Ram 2500 from 2015 was left out of the recall. The MIL indication and subsequent codes related to this failure are the same as being reported in the Warranty Bulletin previously addressed by FCA, X99 6.7 Cummins Turbocharger Actuator Warranty Extension. I was put at risk of an accident due to this happening on expressway. I experienced a loss of power when I certainly needed it to pull over to get to the shoulder. I believe my vehicle and others that were built with these subpar actuators should have been included in this warranty extension. Please advise if further information is needed. The ideal resolution is to be included in the warranty extension of the actuator and have the appropriate part replacement for this issue. Thank you for your time into this matter, Regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

On 3/29/23 while driving approximately 80 miles back home, the vehicle began leaking engine oil and coolant upon acceleration. The vehicle was returned to the shop for repair but the repair failed. On 4/8/23, again the vehicle began to spew oil and coolant upon acceleration. No warning lights came on. The reservoir for coolant is drained of coolant. There is an odor of oil and antifreeze in the cabin which is harmful and poisonous. Also, the engine may fail along with other components on the vehicle without warning as no there is no indicator light warning of the problem.the vehicle was purchased on 3/29_23 from a used car dealership, whom allegedly claims to have inspected the vehicle thoroughly

Loud ticking noise coming from the engine compartment. Dealer says broken exhaust manifold bolts are causing the problem. I contacted chrysler today and they said no recall has been issued to correct and repair the faulty problem. Do not understand why, as I am a 3-time master ase tech and know that exhaust manifold bolts just don't break, and after online research I see there is a definite major problem over the years with these.

This issue relates to code U010c “lost communication with turbo charger supercharger A”. When the engine brake is turned on the engine brake can remain on during this malfunction and the vehicle loses power. If the fault code above occurs at highway speed and the engine brake was activated the engine brake can remain on even if the accelerator is pressed and the engine brake is manually turned off. This situation required me to quickly move to the shoulder and shut the engine off to reset the fault code. This has happened to me several times. My vehicle only has 34k miles but the warranty has expired. The turbo actuator tests ok until the engine is at operating temperature. The actuator electronic control malfunctions at normal engine operating temperature. The dealer wants to replace the entire turbo. There seems to be many aftermarket companies that make replacement actuators so I believe this is a common problem with Cummins turbo Diesel engines from 2012 to 2019 models.
