Thor Motor Coach Tuscany Recall 17V284: Brakes May Stay Engaged on Towed Vehicle, Risking Fire

NHTSA campaign 17V284, reported April 27, 2017, 4 vehicles potentially affected.

What this recall means for you

This recall affects certain motorhomes with a heavier, adjustable, straight foot pedal. The brake activation signal sent to some towed devices may not turn off when the motorhome's service brakes are released. As a result, the towed device's brakes can stay engaged or drag, depending on how they are configured.

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

The repair is free. Freightliner dealers will modify the affected pedal assemblies at no charge. Contact DTNA customer service at 1-800-547-0712 or Thor customer service at 1-877-500-1020, referencing recall FL723AB. Check your vehicle identification number (VIN) for open recalls.

Component
SERVICE BRAKES
Problem
Thor Motor Coach (Thor) is recalling certain 2015 Tuscany motorhomes built on a Freightliner Custom Chassis Corporation (FCCC) XCM, XCR, or XCL motorhome chassis manufactured by Daimler Trucks North America (DTNA).
