Everything below is an owner-reported complaint submitted to NHTSA about the 2027 Kenworth T680, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
On XXX, while operating a 2027 Kenworth T680, VIN [XXX], at approximately 64 mph on [XXX], the truck experienced a sudden electrical and control-system failure while in motion. The steering became extremely difficult or unresponsive, and the wheels or brakes appeared to lock, creating an immediate risk of a serious collision. I was able to bring the vehicle to a stop without striking another vehicle. Following the incident, the instrument panel displayed multiple “Data Error” messages, an ABS warning, traction-control warning, Predictive Cruise Fault, and missing engine RPM, oil, coolant, torque and boost information. The electronic parking brake would not release even though both air systems displayed approximately 100 PSI and the transmission displayed Neutral. The truck could not be safely driven and was towed to Youngstown Kenworth Inc, [XXX]. The dealership has verbally advised that the ECM, or control module identified by the repair shop as the ECM, is not connecting or communicating with the truck. The vehicle remains out of service pending diagnosis and repair. The truck’s manufacturing label is dated XXX. NHTSA recall 26V485000, PACCAR campaign 26PACD, covers certain 2027 [XXX] T680 tractors produced from XXX. That recall concerns possible oil contamination in the Power Distribution Center, which can cause loss of power to the engine, ABS, exterior lighting, windshield wipers or defrost system. I request that NHTSA document and investigate this incident and determine whether the loss of electrical communication, steering assistance and braking or wheel control is connected to recall 26V485000 or another safety defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
