NHTSA Complaint #11425348 — 2018 NEWMAR DUTCH STAR

When preparing to leave, my coach received a check engine light, and 3 error codes from the Cumins ECU. SPN 3364, 1761 and 3031. All FMI code 9. My engine is Likely now debated to 5% power and I was just able to return it to the driveway at the house. Thankfully I hadn’t gotten onto the busy interstate when it happened. After contacting Spartan Chassis, they informed me that I needed a new DEF Head unit. This has been a major issue across the industry. The part is manufactured by SHAW and parts are not available. I was told by Spartan “August or September” for parts. I am unable to move the coach for fear that it is in fact debated to 5% so will need to have a mobile mechanic dispatched to replace. I understand the need for emission controls, but to derate the engine because we might have a little bit dirtier tailpipe until its fixed…. Major safety issue as there is NO workaround.
