FREIGHTLINER Complaints

Multiple Episodes of vigorous Sudden Application of Active Brake Assist, sometimes with a sudden dip, occasionally without a noticeable inciting issue. Often Occurs at Hiway speeds, on a narrow bridge with car slowing to 5 mph. At low speeds break assist may turn off and able to resume driving, sometimes requires restart of engine to clear brake assist. Drivers following behind are not happy when this unexpectedly happens, very unsafe. Atteeempts to deal with it through dealer have been unsuccessful or dis,issued.

The contact owns a 2000 Freightliner XC. The contact stated while driving 60 MPH, the check engine warning light illuminated, and the vehicle lost motive power. The contact veered to the side of the road. The contact stated that he turned off and restarted the vehicle, and the vehicle responded as needed. The contact was able to continue driving. The contact stated that the failure had been recurring while driving. The vehicle was not diagnosed nor repaired. The dealer was notified of the failure. The manufacturer was notified of the failure and informed the contact that the VIN was not included in any recalls. The failure mileage was approximately 35,000.

Vehicle was driving fine, then warning lights that ABS system was no longer functioning, cruse control inoiperable, "go to shop immediatly" with no apparent cause. I took it to a shop and they attached the electronic scanner which indicated "Front Right Speed Sensor failed". This is the second speed sensor that I have had replaced this year (the first was one of the rear speed sensors). I replaced the front right speed sensor this morning, but the system has not reset. I hate to drive the vehicle with the warnings still indicated and cruise control inoperable, but I have no choice.

The contact's company owns a 2022 Freightliner M2. The contact stated while driving 60 mph, the front driver seat was not steady and would rock to the side (left and right) and the front passenger recliner was not stable. The contact took the semi truck to the local dealer but was unable to repair the seats. The semi truck was not repaired. The contact called the seat manufacturer and they provided the front driver suspension base and chugger fore and isolator and the front passager recliner kaob kit to be replaced.

The contact experienced the engine failure a couple of days later but did not take the semi truck to any local dealer at the moment. The contact took the semi truck to a third local dealer: Velocity Truck Centers - Greensboro (6420 Burnt Poplar Rd, Greensboro, NC 27409:(336) 668-0911), where they replaced the parts the manufacturer provided. The semi truck was repaired but the driver seat was now rocking 5 inches forward and backward. The failure mileage was approximately 14,000.

Dash light warning lights come on and causes the cruise control to stop working. A total of 6 fault lights comes on and also causes the Adaptive Cruise Control to not work. This is the 3rd Freightliner Cascadia that I have driven in the past 3 and a half years and every single truck has had the same problem. Freightliner has refused to acknowledge that there is a problem. Nobody seems to know what to do to correct the problem. We are owner operators and long haul drivers and needcruise control. Freightliner dealers are almost impossible to get anything repaired because they do not accept appointments and they have so many trucks sitting around waiting for repairs.

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.

My Emplyoer has not fixed anything on the truck, the truck shouldn’t be operating, doesn’t meet DOT Regulations, I was told not to go into any scales or weigh stations, loses air and the air doesn’t build back up properly, I lost all air in my breaks while driving on the road

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.
