Summary
The RAM 4500 has 23 recalls spanning 2009 through 2026, with the most serious recent issue being a software fault on 2025 models where the occupant restraint controller can shut off while driving, disabling airbags, seatbelt pretensioners, and electronic stability control simultaneously.
On the most current production years, 2026 models have a recall where the instrument panel can display brake system warning lights incorrectly, potentially masking a real brake problem. The 2023-2024 model years have a steering column control module that can cross-activate the high beams and turn signals, causing unintended high-beam activation or a turn signal that stays on or flashes in the wrong direction after a lane change. A separate 2023 issue involves certain vehicles where an improperly installed trailer hitch can loosen and detach, becoming a road hazard.
The 2022 model year has an engine control module fault that can short circuit and stall the engine without warning. On 2021 models with the 6.7L Cummins diesel, the intake air heater relay can short circuit even with the ignition off, creating a fire risk. The 2019-2020 model years carry multiple brake line issues: rear brake hoses on some vehicles were undersized and can rupture, and on other 2019-2020 vehicles equipped with aftermarket liquid spring suspension systems, the rear brake caliper line can chafe against a suspension component, wear through, and leak fluid, resulting in partial or complete loss of rear braking. The 2019 model year with the high-output 6.7L Cummins also has a software defect that can damage connecting rod bearings during warm-up, allowing a rod to break, causing sudden engine failure and potential oil contact with hot components. The 2018 model year has brake hoses whose ferrule fittings can corrode and leak fluid, reducing braking ability.
Going further back, 2016-2017 models with a column shifter share a concern with a broader Ram family recall: the transmission can be shifted without the brake pedal depressed or a key present, risking unintended rollaway. A separate 2016-only issue involves a transfer case output shaft that can fracture and cut drive power without warning, and certain 2016 trucks with the 6.7L Cummins built in a narrow August 2015 window have an engine control module that can short circuit and stall the engine. The 2015 model year has front upper control arm welds that can fracture, causing sudden loss of vehicle stability. The 2013 model year, four-wheel drive only, has rear suspension track bar fasteners that can break free from the chassis and allow the rear axle to shift position. The 2014-2015 model years with the 6.4L gasoline engine have a tire speed rating mismatch where the vehicle's governed top speed exceeds what the fitted tires are rated to handle, risking sudden tire failure at highway speeds. On 2010 models with diesel engines and a hydroboost brake system, the power steering reservoir cap can build excessive pressure, causing the brake pedal to return slowly after being pressed.
