Reports submitted to NHTSA, shown in the owner's own words
I drive a 2022 Kenworth T680 equipped with a Bendix collision mitigation / automatic emergency braking system. On multiple occasions, the system has applied the service brakes hard with no real obstacle in front of the truck, creating a serious rear‑end collision risk for vehicles behind me. The events typically occur in rain, fog, or under overpasses and signs at highway speeds with cruise control engaged. The truck suddenly brakes without warning or driver input, dropping speed rapidly in the travel lane while traffic is following. I have documented dates, locations, weather, and traffic conditions for these incidents. In each case, there was no stopped or slowing vehicle in my lane that justified automatic emergency braking. This appears to be a “false positive” AEB activation similar to those NHTSA is already investigating on other Class 8 tractors, where the system misidentifies harmless objects or roadway features and commands an unnecessary stop. These false activations put me and other motorists at risk of a rear‑end crash. The dealer has indicated they are limited in how much they can disable the system for liability reasons, so I am submitting this as a safety defect report and requesting that NHTSA investigate this behavior on Kenworth T680 trucks with this collision mitigation system.

The contact owns a 2022 Kenworth T680. The contact stated that while driving approximately 70 MPH, the Engine Control Module (ECM) or the Engine Control Unit (ECU), started to lose power, eventually displaying a black screen. When attempting to drive and accelerate up to 50 MPH, the vehicle suddenly lost power. The contact stated that a timer displayed a countdown from one hour, and once the timer reached 0 minutes, the vehicle automatically shut off. The contact would coast to the side of the road and wait before restarting the vehicle to continue driving. The vehicle was taken to the dealer, who diagnosed that the ECM/ECU and oxygen sensors both failed and needed to be replaced. The ECM/ECU was repaired. The manufacturer was not informed of the failure. The failure mileage was 450.

Manufacturer communications
A bulletin sent by a manufacturer to its dealers. Not a recall, and repairs are not necessarily free.
STRUCTURE:BODY
Replaced generic SRT codes with bulletin-specific SRT codes.
The new 2.1m day cab lift tools, a Level 3 mandatory tool, are now available to order.
ENGINE
"RMI procedures have been updated to reduce the risk of progressive damage to the rocker arms. Certain EPA 2021 compliant PACCAR MX-13 engines were built with intake valve springs that could fail. This failure can cause significant damage to the engine. New intake valve springs will be installed. Intake Valve Spring inventory is currently limited and has been placed on reserve status. Dealers must submit a TCS365 case as shown. PACCAR Parts continues to receive regular inventory shipments to the PDCs.["
ENGINE
Certain chassis equipped with an engine model year 2019 - 2021 PACCAR MX-13 engine are eligible to receive software improvements to increase vehicle uptime and emissions fault detection. This software update is expected to be available after 10/30/2026.
Due to supplier constraints, an authorized aftermarket surge tank has been made available.
Removed hyperlinks for bulletin migration
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Complaint and recall counts across every year of this model
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
