Trucks May Take Longer to Release Brakes, Raising Crash Risk
Certain 2016-2021 Kenworth T680 trucks with a 2.1m cab and WABCO 6S/6M antilock brake system with drum brakes were built with a standard rear-brake ABS modulator valve instead of a quick release valve.

The anti-lock brake system (ABS) controller can lose battery or ignition power.
Truck May Move Unexpectedly in Cold Weather, Raising Crash Risk
Certain 2018-2020 Kenworth T680 and T880 tandem axle trucks have a parking brake on a single axle and certain automated manual transmissions.

Front Seat Belt Buckle May Come Apart in a Crash
Some 2018 Kenworth T680 and T880 and Peterbilt 567 and 579 trucks may have front seat belt buckle assemblies that were glued instead of sewn during manufacturing.
Trucks Missing Side Reflectors Can Be Harder to See
Certain heavy trucks built from 2013 to 2015 with side extender marker lights lack the required reflex reflectors on those extenders.
Fuel line can burst on long downhill grades
Certain trucks equipped with Cummins ISX15 or X15 diesel engines may have a fuel pump cooling circuit screen that can become restricted, particularly during driving on long downhill grades.
ABS Warning Light May Not Show Loss of Anti-Lock Braking
On certain trucks, the Anti-lock Brake System (ABS) controller can lose battery or ignition power without the dashboard ABS warning light coming on.
Gear Display May Show Neutral While Truck Is in Drive or Reverse
The gear position display on certain trucks with an Eaton UltraShift Plus or Eaton Advantage automated transmission and a right-hand stalk shifter may show the wrong gear.
Truck May Start Moving When Engine Starts in Gear
Certain transmission control software in these heavy trucks may let the engine crank briefly even when the shifter is not in neutral, which does not meet federal starter interlock requirements.

What owners report
See attached document for complaint.
We bought this truck with 401, 000 miles on it. So far we have had to replace the rear ends twice. the whole DPF system, the check engine light still on since the day we bought the truck. We have had 5 NOS sensors put into the truck, 6 input and output sensors put into the truck. This truck has been defective since the day of purchase. We keep having the same error code of p3770 come up evetime we take to shop. The error code has been looked at so many times that even the master techs don't know what is wrong with the truck other then we keep replacing the same stuff over and over again.
The air dryer bracket part number G11-6218 was craked and because of that it wasn't secured to the frame. The air dryer was hanging on the airline with the piece of the broken bracket. It is not secured. That is extremely unsafe because it could brake airlines and trucks would lose its brakes.
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.
I started the truck after not driving for 1 day and a heavy rain storm the day prior. I attempted to drive bobtail when the brakes locked up. The traction control light came on then went back off. Then the adaptive cruise control notification came on. The regon came on then went back off. A speedometer sign with an exclamation mark came up and would not go away. After attempting to go down the road the brakes continued to lock up, would not release and caused the rear passenger tires to go bald and lose my job.
