Service bulletin 21-PBF
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
Safety Recall – Interim Notification - The Daytime Running Lamps (DRLs) may turn off while the vehicle is in motion and the headlamps, fog lamps or turn signals are not on. This is non-compliant with Canadian Regulation CMVSS 108, which states that the DRLs must be on while the vehicle is in motion without certain other lamps being activated. This bulletin will be updated when a repair is available.
