Manufacturer summary

Original wording in English

Some 2026 model year RZ 350e, RZ 450e, and RZ 550e vehicles may exhibit the Diagnostic Trouble Code (DTC) U25521F associated with the level 3 DC fast charging. Under certain conditions, charging may either operate normally or experience failure, with a charging malfunction message displayed on the Multi-Information Display (MID). This condition is attributed to a control logic issue and potential voltage drop affecting Plug-In Charge Control Computer Assembly functionality. The control logic has been modified to reduce the possibility of 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.
