# Service bulletin 09\-015\-23b

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: 10241609
- Published by NHTSA: 2023\-09\-03
- Manufacturer's number: 09\-015\-23b
- Manufacturer's date: 2023\-08\-29
- NHTSA component: EXTERIOR LIGHTING

## NHTSA's summary

Some customers may notice an abnormal noise \(i.e. whine, groan, rattle or squeak\) coming from the front combination lights when turning them on, or a few minutes after turning them off. The noise may be due to contamination by foreign matter during the manufacturing process. The fan motor bearing may become worn out during use. To eliminate the noise, the production process at the supplier and the material has been modified. NOTE: It is normal for some noise to occur within the first few seconds after starting the engine, when the front combination lights perform a self check \(sweep\).

Description of the specific operations: Specific Operation 1 \[MX\-30\]: After using cabin preconditioning or hazard warning lights for approx.15 minutes. Specific Operation 2 \[MAZDA3 and CX\-30\]: After using hazard warning lights for approx. 15 minutes. Specific Operation 3 \[MAZDA3, CX\-30 and MX\-30\]: When both touch sensors are touched at once. Specific Operation 1 and 2 Cause: The touch sensor has been disabled to avoid the unintended locking/unlocking operation caused by rain.
