My 2019 Freightliner Cascadia forward collision brakes activates automatically while on the road without any other vehicle nearby, airbrake malfunction (not released appropriately and fully released) and extremely fuel consumption.

Truck will apply brakes when no objects or vehicles are around. It is very scary and unexpected when the system does this.

Horn fails to work when the truck is cold. After the steering wheel has been moved during operation, the horn eventually begins to work. I had a vehicle drift into my lane on the highway, and when I went to use the horn, it failed to work. Fortunately, I was able to swerve to avoid the other vehicle hitting the front of my cab. I bought this truck brand new from Freightliner. They state that there is no longer a warranty on the horn, which in my opinion should be viewed as a safety item and should not have failed in less than (3) years and under 16,000 miles.
