NHTSA Complaint #11485792 — 2020 FREIGHTLINER CASCADIA

CAS actived with a Collision Warning and applied hard braking for about 1/2 second for a vehicle that stopped in a paved turnout. The stopped vehicle was not in the travel lane. There was a slight left curve and I could see the stopped vehicle. I thought the CAS May trip because I had experience FALSE Collision Warnings many times in the 88,000 miles I have driving this truck. Before the CAS Collison Warning alerted, I was not in cruise control and was accelerating with the throttle. As stated before the CAS applied hard braking for 1/2 second. I have read the Driver’s Manual about the Driver Assist, Active Braking Assist(CAS) Section 5. On page 5.6 Table 5.2 is says that the above situation can trigger Collision Warning and braking. This may be so, however this has on numerous occasions FALSE Warnings, applied partial braking, and 3 times emergency braking for vehicles that were not traveling in my lane. Earlier this year, Freightliner had a road service mechanic in my company yard to verify that current software and working Driver Assistance Systems on our fleet of trucks. Mechanic determined that this truck was up to date and no recalibration was required. I’m very concerned that the CAS will activate in poor weather conditions, causing a lost of control of the vehicle OR I maybe rear ended by a following vehicle when there is no reason for my vehicle to be stopping. I cannot have the CAS deactivated because it would violate manufacturer, company, and insurance policies.
