A proposed class action lawsuit has been filed against automaker FCA US LLC, alleging that the newly introduced 3.0-liter twin-turbocharged Hurricane inline-six engine found in 2025 Ram 1500 pickup trucks suffers from substantial electronic and mechanical defects. The legal action contends that these critical flaws compromise vehicle reliability and present serious safety hazards for motorists on public roads.
According to the complaint, the core of the issue stems from widespread software and hardware deficiencies located within the vehicle's engine control module (ECM) and powertrain control module (PCM). These electronic command units are responsible for managing crucial engine timing, fuel delivery, and overall powertrain operation, meaning any malfunction can immediately cascade into severe drivability problems.
The legal filing details a wide range of dangerous operational failures allegedly caused by these control unit defects. Among the primary grievances cited in the complaint are unexpected vehicle stalling, sudden loss of drive power while traveling at highway speeds, catastrophic power brake failures, and rapid, unexplained electrical battery drainage.
A central point of concern highlighted by the litigation is the remarkably early onset of these mechanical and electronic breakdowns. The lawsuit notes that affected Ram 1500 owners have experienced major powertrain and braking malfunctions when their trucks were virtually brand new, with some vehicles exhibiting critical faults with only a few hundred miles showing on the odometer.
Details of the litigation, which were reported by the automotive consumer website Car Complaints, indicate that the twin-turbo Hurricane six-cylinder engines routinely trigger recurring check engine lights. In addition to dashboard warning indicators, drivers have reported frequent engine misfires, pronounced throttle hesitation, and abrupt drops in overall propulsion during normal operation.
In numerous reported instances, the vehicle's onboard computers react to these electronic and powertrain discrepancies by forcing the pickup into "limp mode." This emergency failsafe protocol drastically restricts available engine power to safeguard mechanical components from further internal damage, but it simultaneously leaves drivers navigating active traffic conditions with severely diminished acceleration.
The lawsuit underscores the severe safety risks associated with unexpected power loss and sudden limp mode activation on multi-lane highways. When a full-size pickup truck unexpectedly loses its ability to maintain cruising speeds or accelerate alongside surrounding traffic, the likelihood of rear-end collisions and dangerous highway traffic disruptions increases considerably.
To demonstrate the extent of these engineering problems, the class action filing includes direct accounts from individual truck owners who faced persistent and recurring issues despite taking their vehicles to authorized dealership service centers for repair.
Among the specific consumers named in the lawsuit is Wisconsin resident Charlene Norberg, who took delivery of a brand-new 2025 Ram 1500 in August 2024. Shortly after acquiring the truck, Norberg encountered repeated stalling incidents during remote start sequences, with the vehicle displaying an alert instructing the driver to "shift to park start."
Following multiple dealership visits to diagnose the stalling issues and investigate persistent, unexplained battery drain, Norberg experienced a severe failure during active operation. While driving on a highway, the truck triggered an engine overheating alert, completely lost its cabin air conditioning, and plunged into limp mode, necessitating an emergency tow back to the dealership.
The complaint also details the experience of Florida truck owner Tim Craig, who purchased a new 2025 Ram 1500 Rebel in May 2025. With only about 1,200 miles logged on the vehicle, the pickup's instrument cluster suddenly illuminated multiple warning indicators alerting the driver that all onboard safety systems had become entirely disabled.
Following the total system shutdown, certified dealership technicians kept Craig's vehicle in their service facility for more than a month to conduct diagnostic assessments. The lengthy service stay ultimately concluded with the dealership replacing the pickup truck's brake booster assembly in an effort to rectify the underlying braking and safety malfunctions.
The lawsuit highlights that authorized dealership repair networks have faced significant hurdles in successfully identifying and permanently fixing the root causes of the Hurricane engine's interconnected hardware and software anomalies. In many instances, vehicle owners are left dealing with prolonged service delays without a definitive resolution to the drivability defects.
Through this proposed class action, plaintiffs are seeking legal remedies and accountability from FCA US LLC on behalf of consumers who purchased or leased 2025 Ram 1500 trucks equipped with the 3.0-liter Hurricane twin-turbo inline-six engine, pointing to the ongoing safety risks and operational disruptions caused by the alleged defects.
