Recall 11V577 affects 6,101 2009-2011 Keystone RVs with IOTA transfer switches that overheat under high electrical loads. Repair is free at any franchised Keystone dealer.
Keystone is recalling 6,101 2009-2011 Fuzion, Montana, and other RVs with the "generator ready" option or a standard generator because the IOTA ITS-50R transfer switch can overheat under high electrical load. Continued use without replacing the transfer switch can damage appliances and increase the risk of fire, injury, and property damage; the dealer repair will be free once Keystone makes it available.

What's wrong?
The transfer switch on 2009-2011 Keystone models with the generator ready option or a standard generator controls where the RV gets power. It switches the electrical feed between the generator and outside shore power, then sends that power to the RV's electrical system. The IOTA ITS-50R switch has to carry high electrical load without letting its connections loosen or overheat.
On affected Fuzion, Montana, Challenger, Alpine, Everest, Avalanche, and related Montana models, the switch fails when exposed to high electrical loads. The connections and wiring inside the transfer switch degrade and overheat. Once that happens, the switch no longer handles power as designed, and the damaged wiring creates an unsafe electrical condition.
There is no warning sign before failure. The recall filing does not identify a light, sound, smell, or other owner-noticeable symptom that reliably appears before the transfer switch fails.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
Continued use before the transfer switch is replaced can damage other appliances and increase the risk of fire, personal injury, and property damage. Limit use until the switch is replaced and schedule the recall work soon. Repair will be free at any franchised Keystone dealer once available.
What should I do?
- Check your VIN to confirm your 2009-2011 Keystone Fuzion, Montana-Mountaineer, Montana-Big Sky, Montana High Country, Montana Big Sky, Montana, Challenger, Alpine, Everest, or Avalanche is included in this recall.
- Contact Keystone customer service at 1-866-425-4369 for the current repair status before scheduling dealer service.
- Reference recall number 11V577 when you call Keystone or speak with a dealer service desk.
- Schedule the free transfer-switch replacement that fixes the overheating electrical connections tied to the fire risk.
- Bring the recall notice if Keystone mailed one, along with any service paperwork for the generator-ready or standard-generator electrical system.
- Avoid high electrical loads in the RV until the transfer switch has been replaced.
What happens at the repair
Keystone's revised repair replaces the transfer switch instead of only inspecting and tightening switch connections under earlier recall 10V-594. Once the dealer repair is available for your VIN, a Keystone technician replaces the transfer switch at no charge. The work addresses overheated wiring and degraded connections inside the switch under high electrical load. Parts and labor are covered under the recall. Call the dealer with your VIN and ask whether the replacement switch is ready before towing or bringing the trailer in.
