Ram 10-Year Powertrain Warranty in Moses Lake

When a covered powertrain part fails because of a defect in materials or workmanship, the warranty pays for the parts and labor to repair it. Mopar groups the covered parts like this:

• Gas engines: the block and its internal parts, cylinder heads, timing components, oil and water pumps, manifolds, oil pan, turbocharger or supercharger, and the seals and gaskets for those parts
• Diesel engines: the block and internals, cylinder heads, fuel injection pump and injectors, turbocharger housing and internal parts, oil and water pumps, manifolds, and the glow plugs and all sensors
• Transmission: the case with everything inside it, the torque converter and bell housing, the range switch, the speed and pressure sensors and the control module. Manual transmission clutch parts are never covered.
• Four-wheel drive: the transfer case and its control module, the axle housings and internal parts, axle shafts, driveshafts, universal joints and their seals

Mopar describes the extension as stretching Ram's standard powertrain coverage of 5 years or 60,000 miles, or 100,000 miles on diesel engines, out to 10 years or 100,000 miles. For a 6.7L Cummins in a 2500, 3500 or chassis cab, that means the mileage ceiling stays where it already was, and the time limit doubles from 5 years to 10.

That matters on a truck that works hard but doesn't cover many miles a year, the kind that hauls to the field, waits out the winter and runs again at harvest. On a gas Ram 1500, the mileage limit rises too, from 60,000 to 100,000. Our Cummins diesel service page covers the maintenance side of keeping that diesel coverage in good standing.

Mopar's terms keep the regular warranty exclusions in place. Among them:

• Normal maintenance, such as oil changes, filters, coolant, tune-ups and worn brake linings
• Damage from poor or improper maintenance, contaminated fuel, or fluids other than those the owner's manual calls for
• Aftermarket add-ons, additives and racing, along with any repair they cause
• Collision, fire, hail, flood and other outside damage
• Any vehicle declared a total loss or titled salvage, junk, rebuilt or scrap
• Towing, rental vehicles, lost time and lost revenue while the truck is down

If FCA ever questions how a truck was maintained, its terms say the owner will have to prove the maintenance was done, and FCA can restrict coverage on a vehicle that was neglected. The FTC adds that you don't have to use the dealer for routine maintenance to keep a warranty in effect, but you should keep records of every oil change and repair.

For a sense of the limits, the 2026 Ram 2500/3500 owner's manual never lets a 6.7L Cummins go past 15,000 miles, 12 months or 500 hours between oil changes, or a 6.4L gas engine past 8,000 miles, 12 months or 350 hours. Run biodiesel blends above B5 in the Cummins and the manual's biodiesel section also keeps oil changes no more than 6 months apart.
