Does the Ram 10-year/100,000-mile warranty transfer to a second owner?

No. The 2026 10/100 powertrain warranty applies to the original retail purchaser or lessee only. When the truck changes hands, powertrain coverage reverts to the standard 5 years/60,000 miles from the original in-service date. The basic, corrosion, and roadside coverages transfer normally.

Which Rams get the 10/100 powertrain warranty?

2026 model-year Ram trucks bought new at retail, gas-powered lineup — fully electric models and certain fleet purchases are excluded. 2025-and-earlier trucks keep their original terms: 5/60 powertrain on gas models and 5/100 on diesels. Confirm your VIN's coverage in writing at the dealer.

Can I service my Ram outside the dealer and keep the warranty?

Yes — independent shops and DIY oil changes are protected by federal law. With a 10-year powertrain term, documentation matters more than ever: keep dated receipts showing mileage, oil spec (and DEF/fuel-filter service on diesels). The longer the claim window, the deeper the records audit when something fails.

Is the Cummins diesel covered longer than the gas engines?

Historically yes — diesel Rams carry 5-year/100,000-mile powertrain coverage versus 5/60 for gas. With the 2026 10/100 program the picture depends on model year and configuration, so verify your truck's exact diesel terms with the dealer before assuming either number.

Will a lift kit or tuner void my Ram warranty?

Not by itself — Magnuson-Moss puts the burden on the manufacturer to show the modification caused the failure. In practice, lifts and oversized tires invite scrutiny on axle, driveshaft, and steering claims, and ECU tunes leave traces that end engine-claim discussions quickly. Modify with your eyes open, especially with a 10-year term at stake.

Ram Warranty Explained (by a Former Warranty Administrator)

Quick answer

Ram trucks carry a 3-year/36,000-mile basic warranty and — new for 2026 models — a 10-year/100,000-mile powertrain warranty for the original owner (earlier years: 5/60 gas, 5/100 diesel). Rust-through coverage runs 5 years/unlimited miles, with roadside assistance for 5 years/60,000 miles.

Ram made the biggest warranty news in trucks: 2026 models carry a 10-year/100,000-mile powertrain warranty — double the previous term and the longest full-size truck powertrain coverage in the business. Read the conditions before you celebrate, though. It's for the original retail owner only; sell the truck and the next owner falls back to the standard 5/60. Fully electric models and some fleet sales are excluded, and pre-2026 trucks keep their original 5/60 gas or 5/100 diesel terms.

From the warranty-admin chair, an original-owner-only decade of coverage changes the math in a specific way: it rewards buying new and keeping the truck. It does nothing for resale value the way Hyundai-style transferable terms do, and the burden of proof stretches with it — a powertrain claim at year nine will get your entire maintenance history audited. Ten years of oil-change receipts is the price of admission; start the folder on day one.

Everything else is the familiar Stellantis package. The 3/36 basic warranty carries the load on a modern Ram — air suspension electronics, the big Uconnect screen, sensors — and all of that becomes customer-pay at 36,001 miles regardless of how long the powertrain term runs. Cummins HD owners have long had 5/100 on the engine side; verify your specific configuration, because diesel, HD, and chassis-cab schedules differ from the headline numbers.

Coverage at a glance

Years OR miles — whichever comes first. US-market terms.

Basic (bumper-to-bumper)

3 years / 36,000 mi

Defects in materials or workmanship on virtually the whole truck — Uconnect, sensors, air suspension components, trim, electronics. Wear items like brake pads and wipers are excluded.

Powertrain (2026 models)

10 years / 100,000 mi

For 2026 model-year Ram trucks: engine, transmission, transfer case, driveshafts, differentials, and axles — original owner only, not transferable (later owners get 5/60). Earlier model years carry the standard 5 years/60,000 miles.

Diesel powertrain (Cummins)

5 years / 100,000 mi

Diesel-powered Rams have historically carried 5-year/100,000-mile powertrain coverage. Confirm how your model year and the 2026 10/100 program interact for diesel trucks — terms vary by configuration.

Corrosion (rust-through)

5 years / Unlimited

Outer-body sheet metal panels perforated by corrosion from the inside out: 5 years, no mileage limit. Other sheet metal carries 3 years. Surface rust isn't covered.

Roadside assistance

5 years / 60,000 mi

24/7 towing to the nearest authorized dealer, flat-tire service, jump starts, lockout help, and fuel delivery.

What the claims counter wants you to know

The 2026 10/100 powertrain warranty does not transfer. If you trade or sell, the buyer gets the standard 5/60 — so it's worth real money only if you keep the truck. Factor that into new-vs-used Ram math.
A decade-long claim window means a decade-long paper trail. Magnuson-Moss protects servicing anywhere, but on a year-8 engine claim the reviewer will want documented oil changes at spec intervals — every one of them. DIY is fine; undated receipts are not.
Powertrain ≠ truck. Sensors, the water pump, alternator, A/C, air suspension, and all electronics live under the 3/36 basic warranty. The most expensive surprises on Rams past 36k (air suspension, Uconnect) are not powertrain items.
Diesel and HD terms differ: Cummins-powered trucks historically carry 5/100 powertrain, and the 2026 program has exclusions (EVs, some fleet). Have the dealer print the warranty block for your exact VIN rather than trusting the ad.
Lift kits and tunes are everywhere in the Ram world and they don't void the warranty wholesale — but a denial only requires showing the mod caused the failure. Oversized tires on a denied differential claim is the textbook example. Keep mods proportionate to what you're willing to self-insure.
