Ram Heavy-Duty Diesel Trucks Can Stall Without Warning

NHTSA campaign 21V880000 · Reported 2021-11-12 · Chrysler (FCA US, LLC)

critical How serious is it? About this label

Serious: the notice says the engine can stall suddenly with no warning, which raises the risk of a crash, and while there is no order to stop driving the truck, you should get the free repair as soon as your dealer can do it.

What's wrong, in plain English

Certain Ram 2500 and 3500 pickups and Ram 3500, 4500 and 5500 cab chassis trucks with the Cummins 6.7-liter turbo diesel engine may have a fuel pump that fails. That pump pushes fuel into the engine at high pressure, and if it breaks the engine can shut off suddenly while you are driving, with no warning first. The dealer replaces the pump, updates the engine computer software, and checks the other fuel parts, replacing any that are damaged.

What you should do

1. Enter your 17-character VIN at nhtsa.gov/recalls to confirm your truck is included in recall 21V880000.
2. Call your Ram dealer to schedule the fuel pump replacement and software update, or contact FCA US customer service at 1-800-853-1403 (recall number Y78).
3. Have the work done — parts and labor are free — and keep the paperwork showing the repair was completed.
