Cummins 6.7L Emissions Recall 67A: What Ram Owners Need to Know (2013–2018)

Driving a 2013–2018 Ram 2500/3500 with the 6.7L Cummins? There’s a new emissions recall—Recall 67A—that delivers a fast, no-cost software update at your local Ram dealer to reduce NOx emissions by adjusting DEF dosing. Below we explain what it is, who’s eligible, what you’ll feel after the update, and how to prep for your appointment—plus a few BD-proven upgrades to keep your truck happy for the long haul.

 Recall 67A: a dealer-installed software update that lowers tailpipe NOx by increasing DEF dosing under certain conditions—no hardware required.

What Exactly Is Emissions Recall 67A?

Recall 67A is a dealer-installed software update for model-year 2013–2018 Ram 2500 and 3500 trucks equipped with the Cummins 6.7L Turbo Diesel. The update revises the signals sent to the DEF injection system to lower tailpipe NOx emissions by increasing DEF dosing under certain operating conditions. There are no parts to replace, and the procedure typically takes less than an hour at your local Ram dealership.

Details and eligibility are outlined on the official Cummins page: Cummins Recall 67A Information. Always verify with your dealer and the official resources before scheduling.

Am I Eligible? Three Easy Steps

What Will I Notice After the Update?

According to the official guidance, the update is designed to improve emissions performance without changing rated power or drivability. For 2013–2015 trucks, owners shouldn’t see a fuel economy impact. For 2016–2018, highway and heavy-load economy is expected to be unchanged; some drivers may see up to about 0.5 MPG lower in city/light-load conditions. DEF usage is projected at roughly ~1.5% of fuel for light loads/empty bed and up to ~2.5% of fuel when heavily loaded. Day-to-day, customers report no change in torque, responsiveness, or horsepower—just the peace of mind that comes with improved emissions control and extended coverage.

“I had the 67A update done and noticed no change in how it drives—now I’ve got warranty coverage for the big-ticket emissions parts.” —Owner feedback noted by Cummins’ 6.7 community

Before You Go: Prep Checklist

About the Special Extended Warranty

Owners who complete Recall 67A are eligible for a Special Extended Warranty on certain emissions-related components. Coverage is generally the greater of 10 years/120,000 miles from in-service or 4 years/48,000 miles from the recall date, with a long-stop deadline noted by the OEM. Always confirm your truck’s exact coverage and dates with the dealer or on the official site.

For the official coverage chart and PDFs, see: Cummins Recall 67A.

If You Notice Issues—What’s Normal vs. What’s Not

A properly completed 67A update shouldn’t introduce new drivability issues. If you feel a light “rumble strip” sensation under gentle throttle (often 35–55 mph) or see rising EGTs on grades, that’s more likely unrelated maintenance (e.g., a tired torque-converter clutch, charge-air leak, or soot-sticking VGT) than the software itself. Use this visit as a chance to baseline the truck and plan maintenance or reliability upgrades.

How BD Can Help You Post-Recall (Reliability & Tow Readiness)

Recall 67A is about emissions software. While you’re keeping the aftertreatment healthy, you can also address common 6.7L “wear-and-tear” items that affect towing, EGTs, and daily drivability—all emissions-friendly upgrades we build for Ram HD:

• Keep the VGT happy: If your turbo is sticking or tired, BD offers 50-state-legal drop-ins and Screamer VGT upgrades for 2013–2018 and 2019–2024 model ranges (see product pages for CARB EO details).
• Lower drive pressure & EGTs: Thick-wall, pulse-divided cast exhaust manifolds (’13–’18 & ’19–’24) withstand heat cycling and improve flow to help your turbo work easier.
• Protect the transmission: If you tow, stabilize cooler flow on the 68RFE with the BD 68RFE Thermostat Bypass. Feeling light-throttle lockup shudder? Consider the Stock-Plus 68RFE Package to add clutch-holding and stability.
• Cold-weather confidence: Eliminate the OE grid-heater internal-nut risk (while keeping full heat output and emissions compliance) with the BD Killer Grid Heater (2007–2024 coverage; see product page).

Frequently Asked Questions

How long does Recall 67A take?
Most dealers complete the software update in under an hour, but plan for service drive time and any additional open campaigns.

Will it change how my truck drives?
The update targets NOx reduction via DEF dosing and is not intended to change torque, horsepower, or responsiveness. Many owners report no noticeable change in feel.

What about fuel economy and DEF?
Guidance indicates no impact for 2013–2015; for 2016–2018, highway/heavy-load economy is expected to be unchanged, with up to ~0.5 MPG reduction in city/light-load use. DEF usage is projected around ~1.5%–2.5% of fuel depending on load.

Is there a warranty benefit?
Yes—U.S. owners who complete the recall may receive a Special Extended Warranty on emissions components (terms apply). Confirm your VIN-specific coverage with your dealer or on the official site.

Does BD perform the recall update?
No. This is an OEM dealer-performed software campaign. BD can help with complementary reliability upgrades once your truck is up to date.
