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.

NHTSA's summary

Certain 2020 – 2025 model year Palisade vehicles may exhibit engine oil leakage at the engine oil filter housing assembly due to deterioration of the housing seal. At Hyundai, we are committed to providing vehicles of outstanding quality and value. In an effort to meet this commitment, the warranty coverage for the Engine Oil Filter Housing Seal under these conditions has been extended to 15 years/180,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners.
