Ram 2500 loss of power problems

Filed Oct 30, 2026 · Brakes, Electrical · AZ

On two occasions, my 2026 Ram 2500 suddenly lost power while I was driving. At the same moment, power steering and power brake assist both failed, with no warning. The vehicle was purchased new in February 2026 and had fewer than 10,000 miles at the time of both failures. First failure (repair opened September 14, 2026): The truck lost power, along with power steering and power braking. The authorized dealer replaced the steering gear and control module, along with several other modules and sensors, and recalibrated the systems. A load and battery test after this repair passed. The vehicle was out of service until September 30, 2026. Second failure (repair opened October 26, 2026): The same thing happened again: a sudden loss of power with loss of power steering and power braking. This time the dealer identified a shorted or damaged battery as the root cause and replaced it, even though the battery had passed a load test a month earlier. The manufacturer has been notified.

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.

The transmission failed. Prior to the failure, the vehicle had an undiagnosed fluid leak believed to be coming from transmission-related hoses/lines. These hoses were replaced; however, the issue persisted and ultimately resulted in transmission failure. The failure occurred while the vehicle was in operation, which caused a sudden loss of power/drive capability. This created a hazardous situation, especially in traffic, as the vehicle was unable to accelerate or maintain speed, increasing the risk of a collision. The fluid leak and subsequent transmission failure were inspected by a service center. The leaking hoses were identified and replaced; however, this repair did not resolve the underlying issue, and the transmission ultimately failed. No indication of symptoms of failure prior.

Vehicle: 2023 Ram 2500 Diesel (6.7L Cummins) – approx. 36,000 miles, under factory warranty Complaint Summary: Our 2023 Ram 2500 diesel is producing visible smoke from the engine bay and a persistent ticking/clicking noise from the engine. This occurs while driving and at idle. We have video evidence of smoke coming from under the hood and recordings of the abnormal engine noise. Safety Concerns: The smoke creates a serious fire hazard and risk of mechanical failure. Engine-bay smoke can indicate an electrical short, fuel or oil leak, overheating component, or exhaust/turbo malfunction. This poses a risk of engine compartment fire, including the possibility of fire after the vehicle is turned off. the federal safety agency Recall 23V‑060 for 2021–2023 Ram HD diesels describes electrical failures that can cause under-hood fires, showing this vehicle line has known fire-related safety issues. The smoke also presents a health and inhalation risk, especially to our children who ride in the vehicle. Diesel/exhaust fumes entering the cabin can cause respiratory irritation and impair driver alertness. A sudden escalation could result in loss of power, breakdown, or fire while driving. Dealer Response: We brought the vehicle to an authorized Ram dealership in February 2026. Despite the truck being fully under warranty, the dealer stated that because there is “no active recall,” they will not repair or further diagnose the problem. No meaningful corrective action was taken. Evidence Available: Videos showing smoke from the engine bay, audio/video of the ticking noise, and dealership service paperwork. We are requesting the federal safety agency investigate this as a potential safety defect due to fire risk, toxic fume exposure, and the manufacturer’s failure to address a dangerous condition in a nearly new, warrantied vehicle. We are paying on this vehicle monthly, are scared to drive with our children in the car. We have to pull over and not drive the vehicle due to how strong the cabin odor is.

Subject: Safety Concern – Vehicle Shuts Down While Driving / Request for Replacement Despite multiple warranty repair attempts, my 2025 Ram 2500 continues to experience unresolved electrical failures. In addition to the previously documented issues, the vehicle shuts down while driving, forcing me to immediately pull over, place the vehicle in park, and restart the engine in order to continue driving. This condition has occurred unexpectedly and without warning. Losing power while the vehicle is in motion presents a serious safety risk, especially during highway or interstate driving. Given that I rely on this truck for work and frequently travel long distances between New Jersey and Texas, this behavior makes the vehicle unsafe and unreliable for its intended use. The truck has already undergone repeated diagnostics, module replacements, software updates, wiring repairs, and battery replacement at authorized Ram dealerships. Despite these efforts, the issue persists. At this point, I have lost confidence in the safety and reliability of this vehicle and do not feel comfortable continuing to drive or own it. I have acted in good faith and allowed multiple opportunities to repair the vehicle. The ongoing shutdowns while driving demonstrate that the defect has not been corrected within a reasonable number of attempts. Requested Resolution: • Immediate escalation of this case due to a safety-related defect • Replacement of the vehicle or trade-assist into another Ram truck • Reimbursement for loss-of-use expenses incurred due to repeated service visits I am requesting a definitive resolution rather than additional repair attempts.

I own a Ram 2500 (VIN: [XXX] ) that has experienced a persistent and worsening rough idle. The engine shakes violently at idle, RPMs fluctuate unpredictably, and the vehicle feels as if it may stall. This occurs at stoplights, in traffic, and after warm-up. The vehicle has been taken to the dealership multiple times for this issue. Despite repeated visits, diagnostics, and inspections, the problem has not been resolved. I was told the condition is “normal” or that a future software update may address it, but the issue continues and is getting worse. In addition to the rough idle, the vehicle has experienced intermittent electrical issues, including warning lights, erratic behavior of vehicle systems, and inconsistent performance. Similar complaints are widely reported by other Ram 2500 owners online, including rough idle, engine surging, stalling, and electrical failures. Why This Is a Safety Concern!!!!! This defect creates a serious safety risk. The rough idle causes violent shaking and unpredictable engine behavior, raising concern that the vehicle may stall while stopped or when maneuvering in traffic. Loss of power or stalling at intersections, in traffic, or while towing could lead to a collision. Electrical issues further increase the risk by potentially affecting engine management, warning systems, lighting, or driver information displays. Online forums and consumer complaint databases show numerous reports of similar issues, including loss of acceleration, stalling while driving, and electrical failures. Because the issue is unresolved despite multiple repair attempts and appears to be systemic, I believe this represents a safety-related defect that warrants investigation.
