23V286000Fuel SystemApril 21, 2023 · 1,027 units

Defect

Forest River, Inc. (Forest River) is recalling certain 2021-2023 Coachmen Galleria, Beyond, Forester, Sunseeker, and 2021-2024 Nova motorhomes, equipped with certain Cummins Onan QG 2800i, and Onan QG 2800i EVAP generator sets. The fuel hose between the inline fuel filter and the Injection Pump Module (IPM) may have inadequate clamp force, possibly resulting in a gasoline leak.

Consequence

A gas leak in the presence of an ignition source increases the risk of a fire.

Remedy

Cummins Dealers will inspect and replace the fuel hose and clamps, as necessary, free of charge. Owner notification letters were mailed May 17, 2023. Owners may contact Cummins at: (800) CUMMINS OR (800) 286-6467. Owners may contact Forest River Customer Service at 1-574-206-7600, or Coachmen Class B customer service at 1-574-825-8602.

Defect

(Forest) is recalling certain 2020-2021 Forest River Forester, Sunseeker, Dynamax Isata and Coachmen Galleria and Prism motorhomes built on Sprinter Van chassis equipped with swivel seats. The wiring harnesses for the front seats may have been routed incorrectly and could become jammed and damaged in the swivel seat frames.

Consequence

If the wiring harness is damaged, the side air bag within the seat may deploy inadvertently or not deploy as designed in the event of a crash, increasing the risk of injury to vehicle occupants.

Defect

Forest River Inc. (Forest River) is recalling certain 2020-2021 Coachmen Galleria, Dynamax Isata, and Forest River Battisti Coach, Forester, and Sunseeker motorhomes, built on 2019 Mercedes-Benz Sprinter chassis. The rear part of the front fender liner may contact and chafe the brake hose, possibly resulting in a loss of brake fluid.

Consequence

Loss of brake fluid can extend the distance needed to stop the vehicle, increasing the risk of a crash.

Remedy

Defect

Forest River, Inc. (Forest River) is recalling certain 2020-2021 Coachmen Galleria and PRISM, Forest River Forester, Battisti and Sunseeker and Dynamax Isata recreational vehicles built on Sprinter chassis with automatic transmission. The operator's manual does not correctly specify certain conditions under which the automatic parking function ("Auto-P") operates.

Consequence

If the driver relies on the Auto-P function as described in the Operator's Manual, vehicle rollaway or movement may occur, increasing the risk of a crash.

Remedy

Forest River will notify owners, and Mercedes-Benz dealers will provide the correct description of the Auto-P function for the Operator's Manual, free of charge. The recall began June 25, 2020.
