What's wrong?
The L.P. gas line on the 2017 Dynamax Isata carries propane from the motorhome's fuel supply to propane-powered equipment. A rubber grommet protects the copper line where it passes through an opening, and a cable tie is supposed to hold that grommet tightly in place.
On affected Isata motorhomes, the required cable tie was not installed during assembly. Without that tie, the grommet is not secured the way the installation instructions require. That leaves the propane line opening less protected and allows liquid propane gas to enter the cabin.
The vehicle has a separate L.P. detector. If gas is present inside the cabin, that detector should sound an alarm. A propane alarm or propane smell is the warning sign owners are expected to notice before the problem becomes more serious.

What's the safety risk?
An unsealed or loose rubber grommet increases the risk of a propane leak and fire. The separate L.P. detector is designed to alarm when gas is present, so treat any alarm as a reason to stop using propane systems and call the dealer. Repair is free at any franchised Dynamax dealer.
What should I do?
- Check your VIN to confirm your 2017 Dynamax Isata is included in this recall.
- Contact a franchised Dynamax dealer to schedule the free grommet inspection and cable-tie repair that helps keep liquid propane out of the cabin.
- Bring the recall notice if Dynamax has mailed one. If not, reference recall number 16V774 when you call.
- Keep the L.P. gas system shut off until the dealer inspects the grommet and secures it.
What happens at the repair
At the dealer, a Dynamax technician inspects the rubber grommet around the copper liquid propane gas line and installs a securing cable tie where needed. The recall repair is free, including parts and labor. For any prior out-of-pocket repair tied to this same grommet or propane line condition, Dynamax has a general reimbursement plan on file. Bring repair paperwork or receipts to the service desk and ask how the plan applies to your repair.
