Service campaign 25-01-029H TSB

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 Tucson Hybrid (NX4 HEV) vehicles may have incorrect drive motor identification codes on the aluminum plate attached to the drive motor housing. Follow the procedure in this TSB to replace the aluminum plate and barcode sticker with the correct drive motor identification.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Vehicles listed
HYUNDAI TUCSON HYBRID2025 (the catalog's model; the bulletin names a series or trim of it)

Listing a model year does not mean every vehicle of it is concerned: the document says which.
