Service bulletin L-SB-0021-20
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
TSB: Some 2019 ? 2020 model year UX 250 Hybrid vehicles may experience a difficult-to-start condition accompanied by a hybrid system warning lamp occurring during below-freezing temperatures (< 32°F). This condition may occur at start-up after a short-distance drive. After performing a Health Check, the Diagnostic Trouble Codes (DTCs) U011087 and U029387 may be present. These codes are because of the IGCT (90987-02025) relay not being able to supply power to HV ECU. Follow the Repair Procedure in this bulletin to address this condition.
