What's wrong?
The engine control module, or ECM, on the 2023 Spartan K2 is the computer that manages engine operation. It reads sensor signals and tells the engine how to run, including fuel delivery and timing. On this motorhome chassis, the engine depends on that module staying powered and communicating correctly.
During production of the affected ECM, a screw in the selective solder fixture backed out of position. That pushed an electrolytic capacitor frame into the printed circuit board, the flat board that carries electrical paths inside the module. The contact can create an internal short circuit. If that happens, the ECM can shut the engine down unexpectedly and the vehicle cannot be restarted.
There is no warning sign before failure. The shutdown can happen without a prior light, sound, or drivability change for the owner to notice.

What's the safety risk?
An unexpected engine shutdown can increase the risk of a crash. If the bus becomes disabled, evacuation in uncontrolled traffic can increase the risk of passenger injury. This can happen without warning, so keep extra distance, avoid unnecessary trips, and contact the dealer for recall guidance. Repair will be free at any franchised Spartan dealer once available.
What should I do?
- Check your VIN to confirm your 2023 Spartan K2 is included in this recall.
- Wait for Spartan's repair instructions before scheduling the free repair.
- Ask a franchised Spartan dealer whether the free ECM and fuse replacement that addresses the unexpected shutdown and no-restart condition is available for your VIN.
- Call Spartan customer service at 1-800-582-3454 with questions and reference recall number 22V599 when you call.
- Drive cautiously until the repair is complete, and choose routes where you can pull over safely if the engine shuts down.
What happens at the repair
The final dealer repair is still being prepared. Once it opens, a Spartan technician will replace the engine control module and the related fuse, free under the recall. The engine control module manages engine operation, so the repair focuses on replacing the electrical parts tied to the short-circuit condition. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, since the affected motorhome chassis are still within their warranty period. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
