2019 FREIGHTLINER CASCADIA Forward Collision Avoidance Automatic Emergency Braking Problems

While approaching an overpass the collision mitigation system activated my brakes nearly causing the vehicle behind me to rear end my trailer, hit my brakes so hard i was thrown forward.

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.

The contact owns a 2019 Freightliner Cascadia. The contact stated that while driving approximately 60–70 MPH, the brake assist system engaged without an object nearby. While depressing the brake pedal, the system released and reset. The Forward Collision Avoidance alarm sounded. The contact called the local dealer and was referred to the manufacturer. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 200,674.

My truck just came to a screeching halt on the interstate with no obstacles in front of it. It nearly caused a major accident. I could not override it. I was approaching an overpass approximately 100 yards away. Collision warning lights went on. Horn started beeping and brakes engaged immediately.

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 Wabco has been contacted and state the system is discontinued and outdated so no support or fixes is offered other than a single software upgrade.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...

ABS AND TRACTION control failed. Because of this, the $ 7,000 automatic collision avoidance system is not working. 300.000 miles on 2019 truck is just ridiculous.
