The 2007-2018 RAM 3500 with the 68RFE 6-speed automatic transmission suffers from premature failure when towing heavy loads (over 10,000 lbs). The 68RFE is a derivative of the older 545RFE and was not adequately engineered for the torque output of the 6.7L Cummins. The overdrive… Repairs typically run $400-$8,000. Severity: high.
What is the 2013-2025 RAM 3500 Aisin AS69RC Transmission Overheating and Converter Shudder?
The RAM 3500 equipped with the Aisin AS69RC 6-speed automatic transmission experiences torque converter shudder, overheating when towing, delayed shifts, and premature wear. The torque converter lockup clutch develops a shudder at light throttle and highway speeds. When towing he… Repairs typically run $300-$3,500. Severity: high.
What is the 2013-2025 RAM 3500 AAM 11.5/11.8 Front Axle Seal and U-Joint Failure?
The RAM 3500 4x4 with the AAM (American Axle Manufacturing) 9.25 front axle experiences premature front axle seal leaks and u-joint failures. Differential fluid leaks from the inner axle seals, contaminating the front brakes. The front axle u-joints (Dana Spicer 60) wear out prem… Repairs typically run $200-$1,200. Severity: high.
What is the 2013-2025 RAM 3500 6.7L Cummins Exhaust Brake Actuator and VGT Turbo Issues?
The RAM 3500 6.7L Cummins equipped with the integrated exhaust brake system experiences failures of the VGT (Variable Geometry Turbocharger) actuator and exhaust brake solenoid.

What is the 2010-2025 RAM 3500 Front Hub Bearing Failure Under Heavy Load?
The front hub bearings (wheel bearing assemblies) in the RAM 3500 fail prematurely, particularly on trucks that carry heavy loads in the bed or tow heavy trailers. The factory hub bearings are adequate for unloaded driving but wear rapidly under sustained heavy GVWR/GCWR conditio… Repairs typically run $300-$700. Severity: medium.
What is the 2010-2025 RAM 3500 Grid Heater Relay Failure (6.7L Cummins)?
The intake grid heater relay fails, preventing the grid heater from warming intake air during cold starts. The grid heater draws significant current (up to 200 amps), and the relay contacts eventually burn and weld or fail open. Without the grid heater, cold-start performance deg… Repairs typically run $80-$250. Severity: medium.
What is the 2010-2025 RAM 3500 Exhaust Manifold Stud Failure (6.7L Cummins)?
The exhaust manifold mounting studs on the 6.7L Cummins break due to repeated thermal expansion and contraction cycles. Broken studs allow the manifold to separate from the cylinder head, creating exhaust leaks that produce a ticking noise and reduce turbo efficiency. The center… Repairs typically run $400-$1,200. Severity: medium.
What is the 2013-2025 RAM 3500 5th Wheel / Gooseneck Prep Wiring Corrosion?
The factory 5th wheel and gooseneck towing prep wiring harness corrodes at the in-bed connector junction, particularly where it connects to the 7-pin and 4-pin trailer connectors under the bed. Water intrusion from rain, truck washes, and bed spray deteriorates the connector term… Repairs typically run $50-$300. Severity: low.
