What's wrong?
The fuel hose on the 2021-2022 Newmar Ventana, New Aire, and Dutch Star motorhomes carries diesel fuel from the fuel pump to the remote fuel filter head. That filter head is the mounted filter assembly that cleans fuel before it continues toward the Cummins L9 engine. The hose has to hold fuel securely while the engine and chassis move and vibrate.
On affected motorhomes built on a Freightliner chassis, fuel can leak from the hose between the pump and the remote fuel filter head. Newmar did not list a separate root cause for the leak. Once fuel escapes the hose, it can collect in an area where heat, electrical arcing, or another ignition source is present, which increases the risk of fire.
There is no warning sign before failure. If you smell diesel fuel, see wetness near the fuel filter area, or notice fuel dripping under the motorhome, treat that as a problem and call a Newmar dealer before driving.

What happens at the repair
The final dealer repair is not open yet. Once available, a Newmar technician will replace the fuel hoses connected to the Cummins L9 diesel engine, free under the recall. Parts and labor are covered. Newmar's general reimbursement plan is on file, so owners who already paid for the same fuel hose repair should ask Newmar customer service what documentation is needed for a reimbursement claim. Use Newmar's recall number DTNA #21V556/FL-897 when you call.
