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.

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)
At highway speed vehicle did not have issues until steering into a hard turn. Steering became very heavy and lost power steering intermittently. Same issue occurred at low speed during turns
When I bumped the ignition key with my knee while driving 75 MPH ; the engine died. I had to come to a complete stop, put the vehicle in park, and press on the brake to restart the engine. I lost power steering while pulling a load in heavy traffic.
The water pump on my 2015 dodge ram 2500 failed while I was driving it causing the serpentine belt to slip off the pulleys and I lost all power steering and for some reason power brakes. This all happened in the middle of negotiating a right hand turn causing me to leave the roadway and travel up an embankment and roll onto the passengers side. The road it happened on was a back country road and my vehicle was the only one involved, thankfully.
While your driving the vel shuts off and you lose power the brakes dont work and you cant drive the vel its happen 3 time in the last week the dealer said it is nothing plus they said theres no recall on anything
While driving approximately 35 miles an hour, my right knee swiped my key fob/key chain and turn the ignition from on, to the acc position thereby turning the engine off. I loss all power and was unaware for a few seconds until the truck from loss of power was slowing down and hard to steer. Was able to get to side of road and restart engine and proceed on without further incident. Upon further examination, it looks like my knees from normal driving will make periodic contact with the key fob and key chain and see this as a potential safety issue since power is lost and air bags may not deploy in an accident.
