# Warranty extension Z14 OL

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.

## Other bulletins for the same vehicles and component

- [26\-01\-082H TSB](/bulletins/11038467.md), 2026-10-14, Warranty extension: ELECTRICAL SYSTEM. Certain IONIQ 5 \(NEA EV\) vehicles may experience Malfunction Indicator Lamp \(MIL\) illumination and false battery overtemperature fault diagnosis caused by water ingress into the high voltage battery system. This condition may cause unnecessary fail\-safe activation, potentially resulting in reduced vehicle performance or limited vehicle operation if the vehicle is continually driven. This bulletin provides the service procedure to update the Battery Management System \(BMS\) software to optimize the fail\-safe activation logic to prevent false activation. Additionally, diagnostic criteria for DTC P1AD300 “Hybrid/EV Battery Abnormal Performance: MISD” has also been improved to enhance diagnostic accuracy.
- [26\-01\-082H DCS](/bulletins/11038466.md), 2026-10-14, Warranty extension: ELECTRICAL SYSTEM. Certain IONIQ 5 \(NEA EV\) vehicles may experience Malfunction Indicator Lamp \(MIL\) illumination and false battery overtemperature fault diagnosis caused by water ingress into the high\-voltage battery system.
