While driving a UPS Freightliner truck (Cascadia Vin number [XXX] ) on [XXX] on [XXX] in Charlotte, North Carolina, the tractor brakes locked down causing [XXX] 's arm to jam into shoulder from having all momentum come to abrupt stop causing seatbelt to yank across shoulder ultimately necessitating surgery and putting me out of work for 6 months+ and ongoing INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.

I was north of Louisville Kentucky on [XXX] traveling at 65 mph and I was in the middle lane and the collision lights came on and the truck abruptly started stopping. Luckily no one was on my right side. I made it to the shoulder of the road. Thank God I wasn’t rear ended by anyone and there were three lanes of traffic.

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.
While operating the vehicle on an open section of highway I passed under an overpass. The collision mitigation system sounded an audible warning and the vehicle abruptly applied momentary maximum braking. Had another vehicle been behind me It likely would have resulted in a rear end collision.

The CMV was on a straight road on a sunny day approaching a standard railroad crossing, and for no apparent reason the emergency braking system engaged. We have video of this incident from the truck. I tried to download it but your system would not allow the format.
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
