Fort Worth, Texas — Daimler Trucks North America (DTNA) announced a recall affecting 1,375 Freightliner and Western Star trucks after engineers identified an engine control module flaw that can shut the engine down without warning, raising the likelihood of a crash.

The defect targets the electronic brain that regulates fuel delivery and ignition timing. When the module fails, power can disappear while the vehicle is in motion, leaving drivers with little or no reaction time. For long‑haul OTR truck driver crews and owner‑operators, an unexpected stall can mean loss of cargo, damage to equipment, and serious safety violations under FMCSA regulations.

DTNA’s recall list includes 2023 Freightliner 108SD and 114SD models, Business Class M2, Cascadia, FCCC MC, MT45, S2C 106CAB, XCM, S2RV 106CAB, XCR, and XCS, as well as 2023 Western Star 4700, 49X and 47X trucks. The company estimates that every vehicle in the recall batch carries the defect. Owners will receive notification letters beginning September 26, 2022, and must reference recall number FL-949 when scheduling repairs. DTNA set up a toll‑free line at 1‑800‑547‑0712 for questions and is working with dealers to replace the faulty modules at no cost.

What This Means for Drivers

CDL‑A drivers who operate the affected models must pull the trucks from service until the repair is completed, or risk violating FMCSA safety standards. Owner‑operators should contact their service provider immediately to arrange a warranty‑covered fix, as downtime can erode profit margins on tight freight contracts. Fleet managers will need to adjust dispatch schedules, reassign routes to compliant trucks, and document the recall actions to stay compliant during DOT inspections.

Industry Reaction

While DTNA has not released statements from specific carriers, safety groups such as the National Truck Driver Registry have urged fleets to prioritize the recall over delivery deadlines. Industry analysts note that this recall adds pressure on trucking companies already coping with driver shortages and a surge in truck driver jobs postings. The episode underscores the importance of rigorous component testing, especially as manufacturers integrate more software‑driven systems into heavy‑duty rigs.
