Defect: Daimler Trucks North America LLC (DTNA) is recalling certain 2019-2021 Freightliner EconicSD vehicles. The routing and securement of certain electrical power cables at the battery relay and ground cable may cause the components to be damaged.
Risk: A damaged power cable wire coming into contact with the ground cable at the battery relay may increase the risk of a fire from overloading the ground connection. Additionally, a damaged ground connection may also result in an unexpected engine stall without warning and inability to restart, increasing the risk of a crash.
Fix: DTNA will notify owners, and dealers will reroute the left ground cable and install a new connection joint, and the battery cables will be reoriented and a new heat sleeve installed, free of charge. The recall began December 24, 2020. Owners may contact DTNA customer service at 1-800-547-0712. DTNA's number for this recall is FL-867.
