Problems owners report
- Recurrent68RFE 6-speed automatic transmission problems
Clunky shifts, feeling outdated, reliability concerns especially under tuned/heavy load, described as a weak spot.
- RecurrentElectrical issues
Intermittent no-start conditions with all warning lights illuminated, battery drain problems despite good batteries/alternator, general electrical gremlins cited as a reason for Lemon Law on a 2024 model.
- RecurrentEmissions system concerns (6.7L Cummins)
Grid heater bolt failures, glow plug issues, EGR system problems requiring cleaning, DPF regeneration needs.

- IsolatedFront-end handling/tracking problems
Wanders, won't track straight, poor driving dynamics noted on a 2024 model.
- Isolated6.4L Hemi gasoline engine reliability
Described as a "horrible" motor, the worst diesel built in the last 30 years (context suggests this is a comparison to diesels, indicating severe dislike), poor long-term reliability.
- IsolatedShifting issues (older models)
Transmission bogging down, refusing to shift past 2nd gear, entering manual mode unexpectedly.
The version owners recommend
For diesel models, versions equipped with the Aisin automatic transmission (or the newer ZF transmission) are strongly recommended over the 68RFE 6-speed. The Cummins engine is the overwhelmingly preferred powertrain for towing and longevity. For heavy fifth-wheel towing, a dual rear wheel (DRW) configuration is considered essential. A Long Bed model is noted for its utility but comes with a significantly larger turning radius. There is no specific trim consensus, but higher trims are praised for their interior quality.
Competitors to consider
Owners compare it most often with the Ford F-350/F-450, Chevrolet Silverado 3500HD, GMC Sierra 3500HD and Toyota Tundra.

Overall sentiment
Mixed sentiment with a clear generational divide. Long-term owners of older models, particularly those with the 5.9L Cummins diesel (pre-2007.5), report exceptional longevity and reliability, with one owner reporting over 600,000 miles on a 2002 model. The 6.7L Cummins diesel engine (2007.5 onward) is frequently praised for its smooth power delivery, torque, and general durability when properly maintained. However, significant and recurrent criticism is directed at other powertrain components, specifically the 68RFE 6-speed automatic transmission, described as clunky, outdated, and a weak point, especially in tuned trucks. The gasoline 6.4L Hemi engine receives isolated but severe criticism, labeled as a "horrible" motor with poor reliability. For newer models (2020+), owner sentiment is cautious, with praise for interior quality and comfort but concerns over electrical issues, front-end tracking problems, and specific diesel engine concerns like the grid heater bolt and glow plug failures. The consensus indicates high satisfaction for dedicated work/towing use with the Cummins engine, but with acknowledged vulnerabilities in the transmission and, for some years, the emissions systems.
Positioning vs competitors
Positioned as a superior value proposition against Ford and GM in the heavy-duty segment, particularly for buyers prioritizing interior comfort and a smooth diesel engine. The Cummins powertrain is a key differentiator. It is frequently compared unfavorably to Ford regarding transmission performance (the Ram's 6-speed vs. Ford's 10-speed or newer units) and front-end handling/stability. Compared to the Chevrolet/GMC Duramax, the Ram is noted for retaining a more reliable CP3 fuel pump for longer. It is considered a more capable and comfortable tow vehicle than a half-ton truck like the Toyota Tundra for serious towing needs. The gasoline 6.4L Hemi is positioned as a less complex alternative to modern diesels for those who tow heavy but not constantly, avoiding diesel emissions system maintenance.
Recommended configurations
Cummins Turbo Diesel engine. Aisin or ZF automatic transmission (avoid the 6-speed 68RFE if possible). Dual Rear Wheel (DRW) for towing over approximately 15,000 lbs. Long Bed for maximum utility, with the understanding it requires more maneuvering space. For gasoline models, the 6.4L Hemi with 4.10 gearing is mentioned for towing. An exhaust brake is recommended for diesel models and should be used frequently. For modern diesels, an extended warranty is suggested by some due to emissions system complexity. Aggressive maintenance, including frequent oil changes (every 5,000 miles is mentioned), is emphasized.
General recommendations
Suitable for owners who need a dedicated tow vehicle for heavy trailers (12,000-22,000 lbs), fifth-wheel campers, or commercial hauling. Ideal for those prioritizing diesel torque and fuel efficiency under load. NOT recommended for buyers who do not have a consistent, heavy towing or hauling need, as the size, cost, and complexity are excessive for light duty. A thorough pre-purchase inspection is critical, especially for used diesel models, focusing on transmission health, emissions system status, and electrical gremlins. For used models, lower-mileage examples from model years known for resolved issues (post-2015 for the 6.7L Cummins is noted as more reliable) are preferred. Be prepared for higher operating costs (fuel, DEF, maintenance) compared to half-ton trucks.
Remarks
The owner feedback spans multiple generations, making specific issue attribution challenging. The 5.9L Cummins (pre-2007.5) is held in very high regard for reliability. The 6.7L Cummins is well-regarded but comes with known, manageable issues (grid heater, emissions). The primary mechanical criticism consistently targets the 6-speed automatic transmission. Newer models (2020+) show a potential increase in complex electrical issues. The gasoline 6.4L Hemi's reputation in the 3500 is notably poor based on the provided data, positioned as a compromise for those avoiding modern diesel complexities. The data includes significant discussion of towing capacity and vehicle size, confirming its primary role as a heavy-duty workhorse.
