NHTSA Complaint #11530075 — 2019 FREIGHTLINER CASCADIA

This complaint comes from a private truck fleet operating over 700 trucks experiencing excessive amounts of false positive emergency braking and/or haptic following distance warnings (brake stab) on 2018-2020 Freightliner Classis Cascadia tractors. The system experiencing the highest incidents are equipped with the Wabco OnGuard Collision Mitigation System. Some of these false positives have resulted in neck and shoulder injuries. False positives occur while approaching bridge overpasses and other road objects such as steel plates or overhead signs. Wabco has been contacted and state the system is discontinued and outdated so no support or fixes is offered other than a single software upgrade. All units have received the software update but still experience false positives. These unexpected false positive occurrences have resulted in injuries, potential loss of control, and accident risks to other motorists. Although false positives have occurred and continue to occur since first receiving trucks with this technology in 2018, the first injury occurred on 3/3/2022. The system should be recalled to provide a solution to the excessive false positives.
