Service bulletin B17120C

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

ServiceNews Article - This article replaces "Don't Worry About the Brown Dust on the Wheels," posted in December 2017. On some arriving vehicles, are you seeing brown dust covering the wheels? Don't worry; it's completely normal.

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
ACURA RLX2018, 2019
ACURA RLX HYBRID2018, 2019 (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.
