What's wrong?

The IOTA ITS-50R transfer switch in affected 2005-2011 Charleston motorhomes manages where the coach gets electrical power. It routes power between sources such as campground shore power and the onboard generator, then feeds the motorhome's appliances and electrical systems. That switch has to carry heavy electrical load without overheating.

On these motorhomes, the transfer switch can fail from heat when RV electrical loads rise in hot ambient temperatures. The problem is tied to elevated electrical demand and heat inside the switch, not to normal wear on a single appliance. When the switch fails, electrical power through the coach is no longer managed as designed, which increases the risk of electrical damage to other appliances.

There is no warning sign before failure. The recall record does not identify an advance symptom an owner can count on before the transfer switch overheats or fails.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific motorhome is included.

What's the safety risk?

Continued use without replacing the transfer switch increases the risk of fire, personal injury, and property damage. No warning sign is listed for owners, so schedule the recall repair soon and ask the dealer if the vehicle is safe to use before the appointment. Repair will be free at any franchised Charleston dealer once available.

What should I do?

  1. Check your VIN to confirm your 2005-2011 Charleston motorhome is included in this recall.
  2. Contact a franchised Charleston dealer to ask whether the free IOTA ITS-50R transfer-switch replacement is open for your VIN.
  3. Reference recall number 12V341 when you call, and keep any owner notice with your service paperwork.
  4. Stop using high electrical loads in the motorhome until the transfer switch is replaced, since continued use with the recalled switch increases fire risk.
  5. Call Charleston customer service at 1-574-295-8749 with questions about scheduling or owner notice status.

What happens at the repair

The known repair is to replace the Iota ITS-50R transfer switch. Once the repair is available, a Charleston technician removes the affected transfer switch and installs a replacement switch at no charge. Parts and labor are covered under recall 12V341. The transfer switch routes electrical power in the motorhome, so the service visit focuses on that component and its wiring connections during replacement.
