Get answers on what the software update is designed to do, how it works, and more.

Let's clear the air.

It’s no secret. The software update enhances overall emissions performance by increasing the injection of diesel exhaust fluid (DEF) into your catalytic system to reduce nitrogen oxide (NOx) emissions from your tail pipe.

 

This process leaves your truck’s torque, horsepower and responsiveness untouched, with little or no impact to fuel economy (based on driving conditions and model year, our tests showed up to 0.5 MPG).

Extra peace of mind, at no extra cost

Once you complete the software update at your local RAM dealership you will automatically receive free special extended warranty coverage. This offer applies to all eligible U.S. owners and lessees. Select your truck’s model year to learn more.

Special extended warranty details

The Special Extended Warranty for U.S. vehicles will cover the cost of all parts and labor needed to repair the items listed below for all owners and lessees who receive the reflash. Eligibility is contingent on Stellantis/FCA’s standard terms and conditions, which include eligibility exclusions for accident, abuse, neglect, and tampering. All applicable existing warranty provisions remain in effect.

Additionally, the Special Extended Warranty will cover the cost of any on-board diagnostic (OBD) scan for malfunctions that trigger the OBD malfunction indicator light (MIL), regardless of whether the malfunction is related to a part covered under the Special Extended Warranty.

 

Although Cummins does not expect damage to the hardware of the Selective Catalyst Reduction (SCR) controller due to the reflash, if any occurs then Cummins will replace the hardware at no cost to the customer and provide a 2-year parts warranty for the replaced part.

 

This Warranty Extension coverage period is the greater of: 10 years from the date of initial sale or 120,000 miles on the odometer (whichever comes first); or 4 years or 48,000 miles from date of Emissions Recall completion (whichever comes first), but not to exceed December 31, 2033 for any eligible vehicle that receives the recall after April 9, 2027.
