Manufacturer summary

Original wording in English

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.

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.
