All 3 Known Issues
The 5.9L Magnum V8 intake manifold plenum gasket is a well-known failure point. The factory gasket degrades and allows engine oil to be drawn into the intake, causing oil consumption, misfires, and loss of power. The plenum pan sits atop the intake manifold and the gasket between them deteriorates over time. This is considered an inherent design flaw in all Magnum V8 engines (5.2L and 5.9L). Hughes Engines offers a permanent fix with a billet aluminum plenum plate that eliminates the gasket entirely.
Common Symptoms
- Excessive oil consumption
- Engine misfires and rough idle
- Oily residue visible through throttle body
- Loss of power under load
- Engine pinging or knocking

The 46RE (V8 gas) and 47RE (diesel) 4-speed automatic transmissions in Ram 1500 trucks are prone to premature failure, particularly the overdrive unit, governor pressure solenoid, and torque converter lockup. These transmissions are based on the venerable A727/A518 Torqueflite design but the electronic overdrive components are the weak link. Transmission slipping, harsh shifts, and stuck-in-gear conditions are common, especially in towing applications. Overheating is the primary cause of failure.
Common Symptoms
- Transmission slipping in overdrive
- Harsh or delayed shifts
- Stuck in 2nd gear (limp mode)
- Transmission overheating under towing
- Torque converter shudder at highway speed

The dashboard on 2nd generation Ram trucks (1994-2002) is notorious for developing severe cracks and warping, especially in hot climates. The ABS plastic used deteriorates from UV exposure and heat cycling. Cracks typically begin around the defroster vents and spread across the entire dash surface. Chrysler faced a class-action lawsuit over this defect. Cracking is cosmetic but can create rattling and a safety hazard if pieces break free during airbag deployment.
Common Symptoms
- Visible cracks spreading across dashboard surface
- Dashboard warping or buckling
- Rattling noises from cracked dash pieces
- Cracking concentrated around defroster vents
