Manufacturer summary

Original wording in English

This bulletin provides information on replacement of the Active Air Flap (AAF) actuator on 2022MY Ioniq 5 (NE1) vehicles that may exhibit AAF warning signs and DTC U028400 while driving. The AAF may not open or close when the DTC U028400 is active due to unstable power supply to the actuator. Follow the procedure in this bulletin to replace the AAF actuator and erase the DTC code.

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.
