• Lights And Instruments#2020330July 20, 2020

  87 units affected

  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 2018-596. 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 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: Thor Motor Coach will notify owners by mail and instruct them to take their motorhome to a Daimler Trucks North America (DTNA) authorized service facility to replace the PDM.

Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a dealer to update the motorhome's Multiplex system.
