What's wrong?
The transfer switch in affected 2008-2011 Jayco Melbourne Class C, Greyhawk Class C, and Octane Sport Utility motorhomes and travel trailers routes electrical power from the available source to the coach circuits. In normal use, it lets the electrical system move between campground shore power and onboard power without feeding both paths at once. The bus bar inside the switch is the metal connection point that carries that current.
In campaign 12V451, the affected Iota-brand transfer switches have an improper electrical connection at that bus bar. A loose or poorly seated connection creates resistance, and resistance creates heat while current flows through the switch. That heat can overheat the transfer switch and melt the surrounding switch material.
There is no warning sign before failure. If the switch overheats, the problem starts inside the electrical equipment, so an owner is not given a clear early symptom to rely on.

What should I do?
- Check your VIN to confirm your 2008-2011 Jayco Melbourne Class C, Greyhawk Class C, or Octane Sport Utility is included in this recall.
- Call Jayco customer service at 1-800-283-8267 to confirm owner-letter status and ask when the free transfer-switch replacement is open for your VIN.
- Reference recall number 12V451 when you contact Jayco or a franchised Jayco dealer.
- Avoid using shore power or generator power if you smell heat, see melting near the transfer switch, or see electrical damage.
- Schedule the transfer-switch replacement once Jayco confirms repair access; the repair replaces the Iota-brand switch tied to overheating at the buss bar.
What happens at the repair
At the dealer, a Jayco technician replaces the Iota brand transfer switch that can overheat at the buss bar connection. The technician removes the affected switch, checks the wiring connection area, and installs a replacement transfer switch so shore power and generator power route through the motorhome or trailer correctly. The dealer repair will be free once available, with parts and labor covered under recall 12V451.
