Daimler Trucks North America LLC (DTNA) is recalling certain model year 2007-2011 Freightliner Cascadia trucks manufactured March 26, 2007, to August 31, 2010. Water may leak into the Signal-detection and Activation Module (SAM) Chassis causing corrosion which may result in electrical shorts or possible intermittent operation of trailer lights.
Intermittent operation of the trailer lights may prevent other drivers from knowing that the truck is slowing or stopping, increasing the risk of a vehicle crash. Additionally, an electrical short in the SAM chassis may result in a a fire.
DTNA will notify owners, and dealers will inspect the SAM chassis for corrosion, replacing it as necessary. Any vehicle that does not have a drip shield mounted in the cab over the SAM chassis will receive one. These repairs will be performed free of charge. An interim letter was sent to owners on May 4, 2015. The recall began on October 8, 2015. Owners may contact DTNA customer service at 1-800-745-8000. DTNA's number for this recall is FL-679.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
