| L-SB-0020-26 Rev1 | 2026-10-08. Service bulletin. ENGINE. 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. |
