Service bulletin 06-001-22
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.

| 06-001-26 | 2026-08-04. Service bulletin. DESCRIPTION Some customers may complain that the electric power steering warning light illuminates after engine start and DTC U2011:1C is stored. Zinc-plated whisker may form inside the EPS motor and trigger the DTC. However, since it is cleared when power is supplied during DTC detection, normal operation can be restored by turning the ignition OFF and then ON. Furthermore, there is no possibility of recurrence. This case may be resolved through a simple inspection or repair without the need for parts replacement, potentially avoiding unnecessary customer waiting time. |

| SA-051-25 | 2025-12-05. Service bulletin. Noise, Vibration, and Harshness (NVH) Diagnostic Guidelines Diagnostic Guidelines When diagnosing NVH concerns, it is essential to first classify the issue into one of three primary categories: Noise, Vibration, or Harshness. Many customer complaints may involve overlapping symptoms, such as both noise and vibration, so identifying the dominant characteristic is critical. Once the primary symptom is determined, follow the appropriate diagnostic path. For example, if a concern includes both noise and vibration but is related to vehicle speed, the vibration diagnostic path should be followed. When considering component replacement during the diagnostic process, it is best practice to start with the lowest cost or most accessible part unless diagnostic evidence clearly identifies a more expensive or complex component as the root cause. This approach helps minimize repair costs and avoids unnecessary part replacements. For example, a growling or bearing whine noise may be mistakenly attributed to internal components in the differential, transfer unit, or transmission, when the actual source is a wheel bearing. Misdiagnosis like this can lead to unnecessary repairs, added time and cost. To help prevent this, always follow the guidelines in the repair procedure. |
| 06-001-25 | 2025-02-05. Service bulletin. Some vehicles may exhibit wear/peel-off of the leather steering wheel surface causing a poor appearance. This concern may be caused by an insufficient wear resistance of the steering wheel surface. |
| SA-060-24 | 2024-09-04. Service bulletin. Before judging a steering wheel as having premature wear or a defect, first clean the steering wheel as explained in the repair information. Some vehicles may have steering wheel stains caused by chemicals such as hand lotions. |
| SA-011-24 | 2024-03-06. Service bulletin. Mazda has developed factory recommended scheduled maintenance services that support all major vehicle systems. Mazda recommends dealers follow the scheduled maintenance tables as cited in the vehicle-specific workshop manual or owner's manual. Services performed outside of Mazda's factory scheduled maintenance are not recommended. These services are unnecessary and create unneeded expenses for your customers. |
| SA-082-23 | 2024-01-06. Service bulletin. Before judging a steering wheel as having premature wear or a defect, first clean the steering wheel as explained in the repair information. Some vehicles may have steering wheel stains caused by chemicals such as hand lotions. |
| SA-008-23 | 2023-03-03. Service bulletin. Some vehicles may exhibit a steering shimmy or body vibration during the PDI test drive or during the first few miles of driving after the vehicle has been delivered to the customer due to flat spots on the tires. Flat spots on tires may be caused by improper maintenance during dealer storage (e.g.: Vehicle was left stationary for a prolonged period of time in high ambient temperatures). |
