2019 FREIGHTLINER CASCADIA Forward Collision Avoidance Warnings 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.

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 Wabco has been contacted and state the system is discontinued and outdated so no support or fixes is offered other than a single software upgrade.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

Cruise control will shut off and then engage again on its own. It will have a hard time to disengage at times. Lane departure goes off when there is nothing there. The collision warning system goes off a lot. Locked up the brakes in the rain causing a slide. Locked up on ice almost causing a jackknife. Then this summer it has locked up when nothing is around. Came to a complete stop, then not releasing the brakes for a few seconds. Luckily, no one was around. It has been in for repair several times. It is in the shop now. I lease this vehicle from Penske. They refuse to give me a safe truck.

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.
