Example complaints

Brakes: “Unit driving on flat road, left front drives started smoking while driving on interstate brakes not being applied, driver stopped and by this time the fire had spread thru the under side of truck and trailer, total loss of truck, trailer and load, belived to be haldex brake can failure leaking air and causing brakes to drag and start on fire”

NHTSA complaint #11166776, filed 2019-01, 150,752 miles

Forward collision avoidance: “Automatic emergency braking is an absolute danger to the motoring public and needs to be eliminated immediately. I am sick and tired of engineer's who don't know their ass from a hole in the ground designing bullshit that doesn't work. Far too many false radar returns and unwanted hard stops to be of any use. I do not own this vehicle but if I did the first thing I would do right after I pull the fuse for the lane departure warning would be to isolate and bypass aeb. This will be done on any vehicles I purchase in the future and I do not care what the law states about doing so”

NHTSA complaint #11415137, filed 2021-05, 393,000 miles

Seat belts: “Seat belt frame cover was cracked and seat belt would not retract. The other side was broken as well with casing coming off. I was in the middle of backing for a delivery and the driver seat retract would not stay in place and the seat kept folding forward causing me to not be able to back the truck. I was told this is due to obese drivers causing the seat to break. Also during the time of my brake issue where are the brakes locked up and on several other occasions the air brake lost pressure for no reason.”
