What's wrong?
On the 2017-2018 Dynamax Isata, the engine water pump circulates coolant through the Cummins 6.7L Turbo Diesel engine and radiator. Coolant absorbs heat from the engine, then releases that heat through the radiator so the engine stays within its designed operating temperature.
The affected Isata vehicles were built with Concentric-brand water pumps that do not have a vent hole. Those pumps can leak coolant. As coolant escapes, the cooling system has less fluid to move heat away from the engine. That leaves the engine cooling system unable to do its normal job as designed.
There is no warning sign before failure. Check for coolant under the vehicle, a low coolant level, or an engine temperature warning after a leak starts, and tell the Dynamax dealer the recall involves the engine water pump.

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?
A leaking water pump can increase the risk of an engine compartment fire. No warning sign is listed, so do not assume the vehicle will alert you before the leak becomes a fire risk. Schedule the repair soon and contact the dealer if you see fluid loss near the engine. Repair will be free at any franchised Dynamax dealer once available.
What should I do?
- Check your VIN to confirm your 2017-2018 Dynamax Isata is included in this recall.
- Wait for Dynamax's owner instructions before scheduling the water-pump repair if your VIN shows an open recall.
- Contact a franchised Dynamax dealer and ask whether the free Concentric water-pump replacement is open for your VIN.
- Reference recall number 17V707 when you call, and explain that the water pump leak risk involves the Cummins 6.7L Turbo Diesel engine.
- Watch for coolant leaks or engine overheating signs, and do not ignore smoke, coolant odor, or warning lights.
What happens at the repair
The source repair calls for the water pumps on the Cummins 6.7L Turbo Diesel engine to be replaced free of charge. Because the remedy status is still listed as under development, do not treat this as a repair that is open for scheduling from this record alone. Once the final dealer repair is available, a Dynamax technician will replace the affected Concentric-brand water pump that lacks a vent hole. Parts and labor are covered under the recall.
