What's wrong?
The inverter wiring in the 2025 Triple E Rv Wonder and Unity motorhomes carries AC power into and out of the inverter. The inverter changes stored battery power into household-style power for onboard equipment, so the wire ends must be stripped to the correct length and clamped tightly in the inverter terminals.
On affected motorhomes, the wire insulation was removed only to 10 mm because the installation procedure was not updated after the inverter manual changed. That shorter exposed section left insulation too close to the terminal connection. Heat can build at that connection, and the wiring can overheat or arc inside the inverter.
The warning sign listed for owners is an overheating or arcing condition at the inverter. An owner report described melting inside the inverter, so visible heat damage or arcing near that area is the signal to stop using the affected electrical system until the recall repair is completed.
