Service bulletin 23-FL-004H
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.

Certain 2015-2019MY Sonata (LFA) vehicles may intermittently exhibit reduced engine power, a “Crank/No Start” condition, and/or have DTC P1233 stored in the ECM due to an internally leaking fuel pump filter housing. For vehicles exhibiting one or more of these conditions, Hyundai is extending warranty coverage for fuel pump filter assembly repair or replacement to 15 years / 150,000 miles from the date of original retail delivery or date of first use (whichever occurs first). This service action and warranty extension is valid for original and subsequent owners.
