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 at various speeds, the Forward Collision Avoidance feature engaged inadvertently. Recently, the contact stated that while driving at 45 MPH, the brake assist system engaged after a plastic bag flew by the vehicle. The Forward Collision Avoidance alarm sounded during the failure. The contact called the local dealer and was informed that the feature could not be deactivated. The manufacturer was also notified of the failure, but no assistance was provided. The failure mileage was approximately 254,180.
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 in 2018, the first injury occurred on 3/3/2022. The system should be recalled to provide a solution to the excessive false positives.
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.
TRUCK SLAMS ON ITS BRAKES RANDOMLY. LOCKS THEM UP WHEN THERE IS NOTHING IN FRONT OF ME AND HAS ALMOST CAUSED ME TO HAVE A BAD ACCIDENT. IT HAS BEEN DOING THIS EVER SINCE I STARTED DRIVING THIS TRUCK AND HAVE PUT 25,000 MILES ON IT. IT HAS 50,000 MILES ON ODOMETER. I HAVE BEEN DRIVING FOR 35 YEARS WITH NO ACCIDENTS AND THIS TRUCK IS GOING TO CAUSE A VERY BAD ACCIDENT. I AM A PENSKE DRIVER BASED IN MT HOPE OHIO AND MANAGEMENT IS DOING NOTHING. WE HAVE 10 OF THESE TRUCKS AT OUR FACILITY WITH THIS BRAKING FEATURE AND WE ARE ALL ABOUT TO QUIT OR HIRE ATTORNEYS. THANKS [XXX]. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
THE AVOIDANCE COLLISION SYSTEM WILL RANDOMLY CAUSE THE BRAKES TO SLAM ON WHEN APPROACHING OVERPASSES WHILE MOVING ON THE HIGHWAY
OUR COMPANY SAYS THE 2019 WILL NOT IDLE WHEN IT IS BETWEEN 30 AND 60 DEGREES , WELL PROBLEM IT CAN BE 58 OUTSIDE AND ITS OVER 70 INSIDE, WELL ROLL DOWN THE WINDOWS , YEAH NOW NO SAFETY FOR THE DRIVER, AND WE HAVE WOMAN OUT THERE TO. SO I DONT THING THEY WANT TO BE RAPED, SO IDLING THE TRUCK SHOULD BE UP TO THE DRIVER NOT THE COMPANY. WITH OUT PROPER SLEEP YOU NOW HAVE SLEEP DRIVERS DRIVING 80,000 POUND WEAPONS ON THE FREEWAYS, FIRST PERSON KILLED WILL BE ON YOUR HEADS IF THIS ISNT TAKEN CARE OF. CRASH PERVENTION SYSTEM ALL OK BUT WHEN DRIVING ON SLICK ROADS AND SOMEONE JUMPS IN FRONT OF YOU THE TRUCK SLAMS ON THE BRAKES AND WE DONT HAVE CONTROL ANYMORE, OH YEAH THIS IS SAFE NOT. THIS NEEDS TO BE ADDRESSED QUICKLY BEFORE SOMEONE DIES.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
