We received a notification yesterday for this problem for our 2017 Ventana (on a 2018 chassis) shown as an Interim Recall Notice, Recall No. 21E-032. Our coach is older than the window of the first recall, and this recall has a different number than the original. We have the L9 engine. They said we'd receive a second letter once the remedy is available.

From the NHTSA website:

"April 20, 2021 NHTSA CAMPAIGN NUMBER: 21E032000
High Pressure Fuel Rail Assembly May Leak Fuel
A fuel leak in the presence of an ignition source increases the risk of a fire.

NHTSA Campaign Number: 21E032000

Manufacturer Cummins, Inc.


Potential Number of Units Affected 45,334


Cummins, Inc. (Cummins) is recalling certain L9 part number D0K3003BX03 and ISX12 part number D563025BX03 diesel engines. The sealing washer may not seat correctly in the pilot bore holes, allowing the high pressure fuel rail assembly to leak.


Dealers will inspect the rail threads and fuel lines, and replace the rail as necessary, free of charge. Owners were notified of the safety risk on June 18, 2021. A second letter will be sent once the remedy is available. Owners may contact Cummins customer service at 1-800-286-6467.


Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to"

They did send me the following inspection though:

Dear Valued Customer:
Spartan RV Chassis has identified a condition on the chassis identified by the Vehicle Identification Number above, where the RTS and RTSe rear suspension component identified is under desired torque value. This service bulletin applies to certain 2018 through 2021 model year K2, K3, and K4 motor home chassis built between 5/7/2018 and 12/3/2020 and equipped with an RTS and RTSe rear suspension supplied by Reyco Granning, LLC.
The labor time for this proactive repair is approximately 1 hour. However, due to scheduling the service provider may need your vehicle for a longer period.
Your satisfaction with Spartan RV Chassis is important to us. Therefore, we are initiating this contact with you so that you will, at your earliest opportunity take your vehicle in to have this proactive campaign completed at no charge to you.
What should you do?
Contact Spartan RV Chassis at 855.589.9836 to locate an authorized service center near you.
Although this is not a safety recall, Spartan RV Chassis is committed to serving you with your best interests in mind.
Thanks for this. Does that mean Spartan will not advise unless we ask?

To be safe I would give them a call. I was surprised they didn't contact me first.

We got our recall notice on this but it is only a Cummins interim notice. The letter advises to "periodically check the fuel rails for signs of leaking and seek repairs if leaks are identified."

Attached is a copy of our letter for your reference.
