NHTSA Complaint #11474018 — 2020 FREIGHTLINER CASCADIA

Wednesday 13 July, 2022 6:45pm PDT. Location US395 Lakeview, OR. Collision Avoidance System(CAS) applied maximum AEB braking for a false detection of obstruction in my travel lane. I was following a pickup and horse trailer at about 45mph. The pickup signaled a left turn and slowed. I applied minimum braking. The pickup and trailer turned clearing my travel lane(the tail end of the trailer was in the opposing lane). At this moment the CAS detected a collision warning(I was still applying some braking) and the AEB slammed on the brakes for about half second then canceled. The CAS has falsely detects numerous incidents a day for the 7 months I have driven this truck. The above incident has been the most severe. Other false incidents range from warning(without braking), cutting power to engine, to applying some amount of braking. At NO TIME during this period did the CAS detected a true obstruction. Manufacturer has checked that truck's system software is current and properly calibrated.
