Service campaign MAS004773 RU 25-20

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 Maserati GranTurismo (M189) MY24 listed in MODISCS+ are involved in a Rapid Update to inspect the glass installed on the right-side door. Some vehicles may have been fitted with a glass lacking the moisture protection on the edge. This condition does not affect vehicle safety, but over time, it may cause visible halos or moisture infiltration, resulting in an aesthetic issue not compliant with Maserati standards.

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.

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