Issue: Certain motorhomes built on a Freightliner chassis could have a problem with the rear-mounted Power Distribution Module (PDM). This could cause the tail lights not to work properly. Note: This recall replaces FL-856 (Transport Canada recall 2020-337). Motorhomes that were repaired under that recall also require this repair. Safety Risk: Brake lights or turn signals that do not work could cause a following driver not to recognize that a vehicle ahead is braking or intends to turn. This could increase the risk of a crash. Corrective Actions: REV Group will notify owners by mail. The corrective actions for this recall are under development.

Issue: Certain motorhomes built on a Freightliner chassis could have a problem with the rear-mounted Power Distribution Module (PDM). This could cause the tail lights not to work properly. Note: This is an expansion of recall 2018-615. Vehicles that had an inspection, but did not have the PDM replaced under the previous recall, require a second repair under this recall. Safety Risk: Brake lights, marker lights or turn signals that do not work properly could make the vehicle less visible. They could also cause a following driver not to recognize that a vehicle ahead is braking or intends to turn. This could increase the risk of a crash. Corrective Actions: REV Recreation Group will notify owners by mail and provide a letter from Daimler Trucks North America (DTNA). This letter will instruct owners to take their motorhome to a DTNA authorized service facility to replace the PDM.
