Automotive manufacturer FCA US LLC is facing a proposed class action lawsuit alleging that its new 3.0-liter twin-turbocharged Hurricane inline-six engine is plagued by severe mechanical and electronic defects. The legal complaint, which focuses on 2025 Ram 1500 pickup trucks, claims that the newly introduced powertrain poses substantial safety risks to consumers due to sudden operational breakdowns.
According to the filed complaint, the root causes of the vehicle malfunctions stem from critical hardware and software flaws within the Engine Control Module (ECM) and the Powertrain Control Module (PCM). These electronic units serve as the central computational brains of the vehicle, and plaintiffs argue that faults within these systems directly disrupt the engine's ability to operate smoothly and safely.
The lawsuit underscores that these powertrain malfunctions are not occurring solely after extended use or high mileage. Instead, the complaint asserts that severe operational defects are manifesting during the earliest stages of ownership, with multiple drivers reporting dangerous failures when their vehicles had only a few hundred miles recorded on the odometer.
Among the most hazardous conditions outlined in the court documents is the abrupt and unexpected loss of drive power while operating at highway speeds. The legal filing alleges that affected trucks can suddenly stall or experience severe hesitation during high-speed travel, creating immediate collision hazards for truck occupants and other motorists sharing the road.
In numerous reported instances, the underlying electronic faults have caused vehicles to unexpectedly drop into "limp mode." While this automated failsafe is engineered to protect engine components during an internal fault, its sudden engagement on public roadways significantly throttles available engine output, leaving motorists struggling to safely maneuver through traffic.
Beyond complete loss of propulsion and stalling, the lawsuit details a broad spectrum of engine performance issues that impair normal driving. Drivers have reported recurring check engine warnings, intermittent engine misfires, and persistent hesitation when attempting to accelerate, indicating deep-seated operational instability across the powertrain.
The litigation further links the alleged control module vulnerabilities to electrical and chassis-level defects. According to the complaint, affected pickup trucks frequently suffer from unexplained battery drain that leaves vehicles entirely incapacitated, as well as critical malfunctions impacting the vehicle's power braking systems.
The broader pattern of consumer complaints, initially detailed by the automotive watchdog website Car Complaints, indicates that these recurring issues persist even after truck owners repeatedly bring their vehicles to authorized dealership service departments for warranty repairs.
To illustrate the severity and real-world impact of the alleged defects, the legal filing highlights specific accounts from individual Ram 1500 owners. One notable case involves Wisconsin resident Charlene Norberg, who purchased a brand-new 2025 Ram 1500 pickup truck in August 2024.
Court documents detail that Norberg's truck repeatedly suffered stalling incidents during remote start routines, frequently displaying a "shift to park start" alert on the instrument cluster. Following subsequent service visits to address persistent battery drain issues, her pickup experienced an engine overheating alert while traveling on the highway, which triggered limp mode, knocked out the air conditioning system, and required the truck to be towed to a dealership.
The class action complaint also cites the experience of Florida truck owner Tim Craig, who purchased a new 2025 Ram 1500 Rebel in May 2025. Like other affected consumers, Craig reportedly began experiencing serious vehicle malfunctions shortly after taking delivery of the pickup.
At approximately 1,200 miles on the odometer, Craig's instrument cluster suddenly illuminated warning indicators stating that all onboard safety systems had been disabled. Authorized dealership technicians kept the vehicle for more than a month to carry out diagnostic testing before ultimately resolving to replace the truck's power brake booster.
The recurring inability of certified technicians to permanently rectify these problems forms a key pillar of the legal argument. Plaintiffs contend that because the defects are tied directly to fundamental ECM and PCM programming and hardware design, standard dealership repairs and component swaps have failed to provide lasting remedies for vehicle owners.
Through the proposed class action, the lawsuit seeks to represent all affected owners and lessees of 2025 Ram 1500 trucks equipped with the 3.0-liter Hurricane engine. The litigation aims to hold FCA US LLC accountable for distributing vehicles that allegedly compromise driver safety and fail to deliver the dependable performance promised by the automaker.
