What's wrong?
The recalled part is the Xantrex Freedom SW 3000 inverter/charger installed in certain 2010-2011 Dynamax Dynaquest Xl, Dynaquest ST, Grand Sport, and Isata motor homes. An inverter/charger manages house electrical power: it turns battery power into household-style AC power for onboard equipment, and it charges the batteries when the motor home is connected to outside power.
Inside that unit, bus bars carry high electrical current between internal components. On the affected inverter/chargers, poor soldering sits close to bus bars that were not tightened enough. If heat melts the solder, the solder can move into the wrong place and create a short circuit inside the electrical equipment.
The recall filing gives no owner symptom to watch for before the short circuit occurs. There is no warning sign before failure.
Who's affected?
Dynaquest Xl, Dynaquest ST, Grand Sport, and Isata are all tied to the same Equipment component for the 2010-2011 model years.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific RV is included.
What's the safety risk?
A short circuit can overheat the inverter/charger and result in a fire. Schedule the recall repair soon. Until the repair is complete, treat electrical overheating as a reason to stop using the unit and call the dealer. Repair will be free at any franchised Dynamax dealer once available.
What should I do?
- Check your VIN to confirm your 2010-2011 Dynamax Dynaquest Xl, Dynaquest ST, Grand Sport, or Isata is included in this recall.
- Contact Dynamax customer service at 1-574-262-3474 to confirm repair scheduling and reference recall number 10V442.
- Schedule the free Xantrex Freedom SW 3000 inverter/charger replacement that adds the temperature sensor and addresses the overheating short-circuit risk.
- Bring the recall notice if Dynamax mailed one, plus any service paperwork tied to the inverter/charger.
- Avoid using the inverter/charger until Dynamax or the dealer confirms the repair is complete.
What happens at the repair
At the dealer, a Dynamax technician replaces the affected Xantrex Freedom inverter/charger with a new inverter/charger that includes a temperature sensor. The repair addresses the short circuit risk tied to solder near bus bars inside the original unit. Dynamax's filing says the replacement is free of charge. Since the remedy status is not listed as available in this source slice, treat the dealer repair as free once available and confirm scheduling with the Dynamax service contact or your franchised service center.
