Severe-duty schedule
The severe-duty schedule is for trucks that see heavy use, such as towing, driving in dusty or off-road conditions, or making short trips in cold weather. For the 2015 Ram 2500, the most significant change for severe-duty use is the oil change interval, which is shortened to every 5,000 miles. The transmission and transfer case service interval is also halved to every 60,000 miles.
Known issues by mileage
- 30,000-60,000 miles: Premature wear of suspension components like tie rods and ball joints, especially on leveled or lifted trucks. Some reports of water pump failure on the 6.4L HEMI V8.
- 60,000-100,000 miles: "Death wobble" can occur due to worn suspension or steering components. The 68RFE transmission may have issues with the torque converter or valve body.
- 100,000+ miles: EGR and DPF issues on diesel models are common, often requiring cleaning or replacement. The 6.4L HEMI is known for potential lifter failure at higher mileages.
Estimated cost per service
- Oil & Filter Change: $50-$150
- Tire Rotation: $20-$40
- Cabin & Engine Air Filter: $40-$80
- Fuel Filter (Diesel): $150-$300
- Brake Fluid Flush: $100-$150
- Coolant Flush: $150-$250
- Transmission Fluid Service: $250-$500
- Spark Plugs: $200-$400
- Timing Belt/Chain Inspection: The 5.7L and 6.4L HEMI engines use a timing chain that does not have a scheduled replacement interval.

- Accessory Belt: $100-$200
- PCV Valve: $50-$100
What you can DIY vs shop
- DIY: Oil and filter changes, tire rotations, cabin and engine air filter replacements, and accessory belt replacements are all relatively straightforward for the home mechanic.
- Shop: Transmission and differential services, coolant and brake fluid flushes, and spark plug replacements are best left to a professional unless you have the proper tools and experience.
