Thor Motor Coach Tuscany Recall 16V437: Brakes May Stay Engaged on Towed Vehicles, Risking Fire

NHTSA campaign 16V437, reported June 15, 2016, 463 vehicles potentially affected.

What this recall means for you

Certain motorhomes built on Daimler Trucks chassis have a heavier, adjustable foot pedal that may fail to turn off the brake activation signal to a towed device when the motorhome's service brakes are released. As a result, the towed vehicle's brakes can remain partly engaged, depending on how that trailer's brakes are set up.

Dragging brakes can overheat and may lead to a fire. Following drivers may also be confused by the motorhome's braking behavior, which increases the risk of a crash.

The repair is free. Thor Motor Coach will notify owners, and Daimler Trucks dealers will modify the affected brake assemblies at no charge. Owners can call Thor Motor Coach customer service at 1-877-855-2867 or Daimler Trucks at 1-800-547-0712, referencing recall RC000116. You can also check your vehicle identification number (VIN) for open recalls.

Problem
Thor Motor Coach (TMC) is recalling certain model year 2014-2016 Tuscany motor homes manufactured February 28, 2013, to August 31, 2015 and built on chassis supplied by Daimler Trucks North America.
