PORTLAND, Ore. – Daimler Trucks North America (DTNA) has agreed to recall 17 model-year 2022 Freightliner Cascadia heavy-duty trucks due to a potential for the automatic emergency braking (AEB) system to malfunction in very unique circumstances.
According to the National Highway Traffic Safety Administration Part 573 Safety Recall Report 22V-443, “In certain specific scenarios where two unlikely events occur independently and simultaneously, there is the possibility that the emergency braking system would not engage.”
DTNA recounted the chronology of defect in a letter to NHTSA reporting, “In calendar year 2021, DTNA theorized that a failure of two independent systems at the same time could cause some lack of brake functionality but considered the likelihood of occurrence so low as to not present an unreasonable risk to motor vehicle safety. In February 2022, DTNA was able to create the simultaneous occurrence of those two failures on a test vehicle, with no accident occurring. . . On June 15, 2022, DTNA decided that, although the likelihood of the dual-simultaneous occurrences being extremely low, that out of an abundance of caution DTNA would perform a voluntary safety recall campaign for this very specific group of vehicles.”
The safety risk is should the AEB system not function, there is a potential for a crash. There have been no crashes reported by Freightliner due to this issue.
The remedy determined by DTNA is the addition of a double-check valve to each recalled vehicle.
Dealers and owners are scheduled to be notified as to the recall by Aug. 21st.
