# Service bulletin SA\-006\-25

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.

- Type: Service bulletin
- NHTSA id: 11013572
- Published by NHTSA: 2025\-02\-04
- Manufacturer's number: SA\-006\-25

## NHTSA's summary

Customers may report no audio when using the infotainment fader function fully adjusted to the rear. If the customer's vehicle is among the trim levels referenced above it is equipped with a 6\-speaker infotainment system and does not include rear door speakers even though there are speaker grills/covers in the rear door panels. MazdaUSA and published vehicle specifications provide the correct information indicating that these trims are equipped with a "6\-speaker audio system". This is a normal condition of the "6\-speaker audio system" and current Mazda CONNECT fader function. Rear speaker diagnosis is not necessary as they are not equipped.
