The front sensor is calibrated wrong. It slams my brakes on road if a shadow is in road, bridges, vehicles parked on side of road, and sometimes if another semi passes me it slams the breaks on. It happens if its just raining out not so much winter because snow and ice blocks the sensor. This has also almost caused accidents as well.

The contact owns a 2023 Freightliner Cascadia. The contact stated that while driving at 55 MPH, the steering wheel locked up, the vehicle became uncontrollable, and the vehicle flipped over. The vehicle was uncontrollable. All the warning lights illuminated. A police report was filed. The contact received injuries to her back and was taken by ambulance to a hospital, where medical attention was provided. The airbags deployed. There was an unknown substance leaking from the vehicle. There was no reported fire. The vehicle was towed to an unknown location. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was unknown.
The vehicle does not have the hood rear view convex mirrors.. The hood mirrors are use for rear to side view blind spot that the passenger or driver side mirrors cannot see. For instance entering or crossing a two way divided highway with no traffic lights, the hood mirrors is use to view when entering without on coming vehicle in a blind spot brushing past your engine compartment or passenger side. Also needed for parking towards the blind spot passenger side or docking without a spotter. I noticed there a group of such Freightliner missing the two hood rear view mirrors
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.
