Freightliner Cascadia Recall 15V127: Trailer lights may fail; electrical short can cause fire

NHTSA campaign 15V127, reported March 4, 2015, 45,036 vehicles potentially affected.

What this recall means for you

Water can leak into the Signal-detection and Activation Module (SAM) chassis on certain 2007-2011 Freightliner Cascadia trucks built between March 26, 2007, and August 31, 2010. The water can cause corrosion, which may lead to electrical shorts or intermittent operation of the trailer lights.

If the trailer lights work only intermittently, other drivers may not know the truck is slowing or stopping, which raises the risk of a crash. An electrical short in the SAM chassis may also cause a fire.

Dealers will inspect the SAM chassis for corrosion and replace it if needed, and any truck without a drip shield over the SAM chassis will receive one. These repairs are free. Owners can contact Daimler Trucks North America customer service at 1-800-745-8000 (recall FL-679), and should check their VIN for open recalls.
