What is the 2011-2023 RAM 1500 Transfer Case Shift Motor / Actuator Failure ('Service 4WD', Won't Engage 4-High or 4-Low)?

4WD-equipped Ram 1500 trucks use an electric shift motor (encoder/gear motor) bolted to the BorgWarner transfer case to move between 2WD, 4WD-Auto, 4-High and 4-Low. The motor's internal plastic gears wear or strip, and water/road-salt intrusion corrodes the connector and motor w… Repairs typically run $300-$900. Severity: medium.

What is the 2013-2022 RAM 1500 A/C Condenser Leak / Loss of Cold Air (Warranty-Extension Defect on Some Trucks)?

The front-mounted A/C condenser on 4th- and 5th-gen Ram 1500 trucks develops refrigerant leaks from corrosion and tiny pinholes, sometimes because units were not built to specification. Once refrigerant escapes, the system blows warm and the compressor can stop cooling or shut do… Repairs typically run $500-$1,200. Severity: medium.

What is the 2009-2023 RAM 1500 Rear Axle Pinion Seal Leak and Differential Whine on Accel/Decel?

Ram 1500 rear (and sometimes front) differential pinion seals weep gear oil at the pinion flange, leaving residue on the driveshaft yoke and a wet spot at the front of the diff. The leak itself is minor, but improper repair is the bigger problem: if the pinion nut is not torqued… Repairs typically run $200-$1,500. Severity: medium.

What is the 2011-2021 RAM 1500 P0420/P0430 Catalytic Converter Inefficiency on 5.7L HEMI?

Ram 1500 5.7L HEMI trucks commonly throw P0420 (Catalyst System Efficiency Below Threshold, Bank 1) and P0430 (Bank 2). On these engines the most frequent true cause is not a worn catalyst but an exhaust leak — a cracked exhaust manifold or broken manifold bolts (the same source… Repairs typically run $250-$2,500. Severity: medium.

What is the 2019-2024 RAM 1500 12-Inch Uconnect 5 Touchscreen Blank/Black Screen and Vertical Lines (5th-Gen DT)?

The optional 12-inch portrait Uconnect 5 display (Android Automotive) on 5th-gen DT Ram 1500 trucks fails in several ways distinct from the older 8.4 Uconnect freeze/reboot issue. Owners report the screen going completely black/blank and not turning on, vertical lines across the… Repairs typically run $300-$1,700. Severity: medium.
