Multiplex Ecm: Electrical System recall

What's wrong

Firefly Integrations, LLC (Firefly) is recalling certain model G12 Multiplex Electronic Control Module (ECM) units, part number 130010113A, installed in Thor Motor Coach vehicles with a 38XL floor plan. A software error prevents the awning control from being locked in certain situations as intended.

Why it matters

Unlocked controls allow the awning to be extended while the vehicle is moving, increasing the risk of a crash.

The fix

Dealers will update the ECM software, free of charge. Owner notification letters were mailed March 12, 2025. Owners may contact Firefly customer service at 1-574-825-4600.

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 nhtsa.gov.
