NHTSA
Recalls & service bulletins
How to check a Cummins-powered pickup, truck, bus or motorhome for recalls and service bulletins with official NHTSA tools, plus the campaigns we verified ourselves. Ram trucks first; other vehicles and Cummins engine (equipment) recalls from section 05.
01Check recalls by VIN
- Find the 17-character VIN on the lower driver-side windshield, the driver door jamb sticker, or your registration.
- Enter it at nhtsa.gov/recalls.[1]
- Any open, unrepaired safety recall on that truck is listed. Recall repairs are done free by a dealer.
NHTSA notes that a VIN search shows unrepaired recalls from manufacturers that report that way. A result of zero means no open recall on that VIN, not that the model never had one.[1]
02Find TSBs (manufacturer communications)
- On nhtsa.gov/recalls, search by year, make and model instead of VIN. For 1989-2010 trucks the make is usually Dodge; from 2011 it is Ram.
- Open the results and look for Manufacturer Communications. That's where technical service bulletins and similar documents are summarized.[1,2]
- Note the bulletin number and take it to a dealer or a shop with factory service information access for the full procedure.
Shortcuts to NHTSA's vehicle pages: 1996 Dodge Ram 2500 1997 Dodge Ram 3500 2001 Dodge Ram 2500 2002 Dodge Ram 3500 2004 Dodge Ram 2500 2006 Dodge Ram 3500 2019 Ram 2500 2021 Ram 3500
Researching in bulk? NHTSA also publishes the manufacturer-communications data as downloadable files on its Datasets and APIs page.[2]
Why no bulletin text here? TSBs are the manufacturer's copyrighted documents. We point you to the official summaries rather than copying them, and we don't list bulletin numbers we haven't confirmed on nhtsa.gov.
03Engine-related recalls we verified
Each campaign below was confirmed in NHTSA's official recall data on 2026-10-19 by querying the 2500/3500-class Dodge and Ram pickups (D/W250-350 for 1989-1993) for every model year from 1989 to 2026 and keeping only campaigns that concern the Cummins engine or diesel-specific parts.[3] Summaries are in our own words; the campaign number links to its NHTSA record. This is not a complete recall list for any truck.
5.9L Cummins 12-valve (6BT) 1989–1998
We searched NHTSA's recall data for Dodge Ram 2500/3500 (1994–1998) and Dodge D/W250–350 (1989–1993) and did not find a campaign specific to the Cummins engine. That does not mean none applies to your truck: other recalls (brakes, steering, lighting and more) exist for these years, and only a VIN check is definitive.
5.9L Cummins 24-valve ISB (VP44) 1998.5–2002
We searched NHTSA's recall data for 1998–2002 Dodge Ram 2500/3500 and did not find a campaign specific to the Cummins engine or VP44. Other recalls exist for these model years, so run your VIN.
5.9L Cummins common-rail ISB (CP3) 2003–2007
These are the engine- or diesel-specific campaigns we found in NHTSA's data for 2003–2007 Dodge Ram 2500/3500. Your truck may have other open recalls; a VIN search is definitive.
- 03V-033
After long stretches on cruise control, engine idle speed could stay elevated. The fix was a reprogram of the Cummins engine controller.[3]
- 05V-462
A driver exiting with the engine running could leave the shifter short of Park. The remedy was a software change that adds an out-of-park warning chime.[3]
6.7L Cummins (ISB 6.7) 2007.5-present
Engine- and diesel-specific campaigns we found in NHTSA's data for Dodge/Ram 2500 and 3500 (2007–2026). Some also cover cab-chassis trucks; two apply only to cab chassis. Newer trucks have many non-engine recalls too, so always run your VIN.
- 08V-641
An under-hood silencer (insulation) pad could sag onto the EGR cooler, creating a fire risk. Dealers added a support bracket.[3]
- 14V-635
Electrical connectors at the diesel fuel heater could overheat and lead to a fuel leak. Dealers fitted an upgraded connector/terminal kit and checked the heater for leaks.[3]
- 15V-592
The engine control module could short-circuit and stall the engine. Affected trucks got a new ECM.[3]
- 17V-562
Some replacement-brand water pumps built without a vent hole could leak coolant. Dealers replaced the water pump.[3]
- 19V-498
Fuel lines could leak into the engine compartment. Dealers inspected the lines and replaced them where needed.[3]
- 21V-880
- 21V-163
The solid-state intake heater grid relay could short and cause a fire. NHTSA lists this campaign as superseded by 21V-798.[3]
- 21V-798
Expanded relay campaign (relay inspection/replacement; owners told to park outside until repaired). NHTSA lists it as superseded by 23V-060.[3]
- 23V-060
Final, expanded relay campaign: the heater grid relay could short with the key on or off. Dealers replace the relay; park outside until it is done.[3]
- 22V-642
Some engine control modules were built with a misaligned capacitor that could short and cause loss of drive power. Dealers replace the ECM.[3]
- 20V-511
Engine warm-up protection could be inadequate, risking rod-bearing damage. The remedy was an engine calibration update. (Cab chassis only, not pickups.)[3]
- 21V-439
Engine software might not warn the driver about low oil volume. The remedy was a calibration update. (Cab chassis only.)[3]
04Recall vs. TSB
- Recall
- A safety-related defect or non-compliance. The manufacturer must remedy it for free, and owners are notified by mail.
- TSB
- A technical service bulletin: repair guidance sent to dealers for a known condition. It is not a recall, and a repair under a TSB isn't automatically free outside warranty.
05Trucks, buses & RVs: vehicle vs. engine recalls
For a medium- or heavy-duty truck, a bus or a motorhome, there are usually two companies that can recall parts of it, and NHTSA files them differently.[1,37]
- Vehicle recall ("V")
- Filed by whoever built the vehicle or chassis (Freightliner, International, Blue Bird, Nissan, a fire-apparatus builder and so on). Campaign numbers look like 21V-538. These are what a VIN search at nhtsa.gov/recalls shows.
- Engine (equipment) recall ("E")
- Filed by Cummins against the engine itself, which NHTSA treats as equipment. Numbers look like 18E-081. Cummins tracks the affected engines by engine serial number (ESN), so a VIN search may not list them.
- Search the VIN at nhtsa.gov/recalls for vehicle recalls.
- On the same page, switch to the equipment search and look up Cummins, or open the campaign number from a family page, then compare the engine models, build dates and part numbers it lists with your engine.
- Give the ESN (section 06) to a Cummins-authorized service location to confirm whether an engine campaign applies and has been done.
The NHTSA recall search covers "vehicles, car seats, tires and other equipment". When a Cummins recall involves a vehicle maker's installation, the vehicle maker often files its own V campaign too; several of those are listed below.
06Find the engine serial number (ESN)
The ESN is on the Cummins engine dataplate and is generally 8 digits. The engine's operation and maintenance manual (available through Cummins QuickServe) shows the plate location in its "Engine Identification" section.[38] More on the identify page.
07Other Cummins families: campaigns we verified
Each campaign was opened in NHTSA's campaign records on 2026-10-19. We kept engine-related campaigns we could tie to a family page, with summaries in our own words. This is a selection, not a complete list: NHTSA holds hundreds of Cummins equipment campaigns.[37,39]
Cummins ISV5.0 (5.0L V8 Turbo Diesel) 2016–2019
Nissan files Titan XD recalls under the model name "TITAN" in NHTSA's data (searching "TITAN XD" returns nothing), so use the VIN search. The two "E" campaigns were filed by Cummins against the engine itself.
- 16V-847
A temporary cap on the fuel tank breather tube may not have been removed at the plant, which could make the fuel gauge read wrong and let the truck run out of fuel. Dealers inspect the breather tube and replace the tank, sending unit or tube as needed.[9]
Vehicle recall (filed by Nissan North America) · about 12,112 units
- 17E-021

Engine recall (filed by Cummins) · about 227 units
- 18E-112
The air compressor belt could slip, cutting compressor output and with it air-brake performance. The fix moves the refrigerant compressor to a new low-mount layout.[11]
Engine recall (filed by Cummins) · about 381 units
- 18V-892
Bus-maker counterpart to 18E-112: a slipping compressor belt could reduce air output enough for the parking brake to apply on its own. Dealers fit a shorter belt.[12]
