Service bulletin CAN 26-027

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The headlights may contain a software defect, which can cause the low beam headlights to illuminate improperly. Reduced low beam headlight illumination can decrease roadway visibility and increase the risk of a crash. Daimler Truck North America authorized service facility will remedy the affected vehicles by updating the relevant software to allow sufficient low beam headlamp light intensity after operating in high beam mode under elevated ambient temperatures.
