Manufacturer summary

Original wording in English

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.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
