# Service bulletin 09\-031\-21\-3831

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

Some customers may complain that the driver’s side outer mirror glass vibrates. This is due to a structural gap between the outer glass mirror holder and the mirror glass causing the mirror to vibrate when the vehicle body vibrates at high speeds. To eliminate this concern, double sided tape has been applied between the outer glass mirror holder and the mirror glass.

- [09\-014\-23a](/bulletins/10240385.md), 2023-08-03, Service bulletin: STRUCTURE; VISIBILITY:REARVIEW MIRRORS/DEVICES. Some vehicles may experience white\-streak stains appearing on the front door that look like they seeped out from under the outer mirror base. This is caused by water intruding from gaps of the outer mirror body and/or the hinge of the outer mirror, and corrosion occurring on the aluminum die\-cast inner base in the outer mirror. Water, including white\-salty corrosion, may drip out from gaps under the outer mirror base resulting in white stains on the front door. To eliminate this concern, the front outer mirror inner base has been modified.
