Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Altec Industries, Inc. has received notification from Kenworth Truck Company that a condition exists relating to motor vehicle safety, compliance, or emissions in a vehicle equipped with Altec equipment. Kenworth Truck Company has decided that certain Vehicle Model Year 2023-2026 T180 / T280 / T380 / T480 chassis built from 7/5/2022 through 12/20/2024 fail to conform to Federal Motor Vehicle Safety Standard (FMVSS) No. 101 - Controls and Displays and FMVSS No. 108 - Lamps, Reflective Devices, and Associated Equipment. The Exterior Lighting Switch (ELS) in certain vehicles may not function. It is non-responsive and can be reset only by a key cycle. If the ELS fails, the hazard lights and the backlight brightness adjustment may not function. As a result, the lack of hazard lights may not alert other drivers. Failure to adjust the backlight brightness may distract the operator or make it difficult to see critical safety information, which may increase the risk of a crash. No warning precedes this condition.
What this bulletin may mean before buying
Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
