What is the 2014-2022 RAM 1500 EcoDiesel Fuel Pump Failure / Stalling?

The 3.0L EcoDiesel engine can experience fuel pump failures and stalling issues. The high-pressure fuel pump (CP4) is sensitive to fuel contamination and can fail catastrophically, sending metal debris throughout the fuel system. Water in fuel accelerates failure. Repairs typically run $800-$12,000. Severity: high.

What is the 2013-2022 RAM 1500 Power Tailgate Unlatches and Opens While Driving (Recall)?

Two separate, widely-publicized recalls cover Ram 1500 tailgates that can pop open while driving. On power-locking-tailgate trucks (NHTSA 19V-347, expanding the earlier 18V-486), the tailgate actuator limiter tab can fracture and let the tailgate unlatch and drop while moving. A… Repairs typically run $0-$0. Severity: high.

What is the 2013-2023 RAM 1500 ZF 8-Speed Transmission Problems?

The ZF 8HP 8-speed automatic transmission can experience harsh shifting, hesitation, and jerky behavior. Some units have failed prematurely. Early model years (2013-2016) seem most affected. Multiple TSBs have been issued for software updates. Repairs typically run $150-$6,500. Severity: medium.

What is the 2009-2019 RAM 1500 Exhaust Manifold Bolt Breakage?

The exhaust manifold bolts on HEMI engines are prone to breaking due to heat cycling. Broken bolts cause exhaust leaks, ticking noise on cold start, and potential exhaust smell in cabin. The rear bolts on both sides are most commonly affected. Repairs typically run $100-$700. Severity: medium.

What is the 2011-2023 RAM 1500 5.7L HEMI Water Pump Leak From Weep Hole and Shaft Seal?

The mechanical, belt-driven water pump on the Ram 1500 is a long-standing weak point across Chrysler products. The shaft seal and bearing wear, and coolant begins seeping from the weep hole at the bottom of the pump. Failures are reported across a wide mileage range, from as low… Repairs typically run $250-$700. Severity: medium.

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 2013-2024 RAM 1500 ZF 8HP70 8-Speed Torque-Converter Shudder / Harsh Shift / Limp Mode?

The 8-speed (ZF 8HP70 / TorqueFlite) develops a torque-converter clutch shudder felt as a vibration/judder around 30-50 mph light throttle, along with harsh downshifts, drive-engagement slam, and occasional limp mode (stuck in one gear with CEL). Root causes are degraded/aged tra… Repairs typically run $300-$3,500. Severity: medium.

What is the 2009-2018 RAM 1500 Front Wheel Bearing / Hub Assembly Failure (Humming/Growling Noise, ABS Light)?

4th-gen Ram 1500 front wheel bearing/hub assemblies wear out relatively early (some as low as ~50k miles), producing a humming or growling noise that rises with speed and changes with steering load. Because the wheel-speed sensor is integrated into the hub, a failing bearing freq… Repairs typically run $200-$600. Severity: medium.

What is the 2016-2022 RAM 1500 Cab Water Leak From Rear Window / Third Brake Light Into Headliner and Floor (Class-Action, TSB)?

Ram 1500 cabs leak water in through the roof-mounted third brake light, the rear cabin/sliding window, and the roof antenna base. Water tracks along a channel from the third brake light down the passenger A/C-pillar to under the seat, soaking the headliner and carpet and causing… Repairs typically run $50-$600. Severity: medium.
