| SA-008-23a | 2023-07-05. 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). |
| SA-012-22 | 2022-04-06. Service bulletin. Some customers may complain about the infotainment system and/or the MyMazda App showing incorrect tire pressures and/or tire pressure missing. This may be caused by: Incorrect calendar entry (month/day/year) after a battery disconnect *Infotainment system software update. *BCM TPMS unlearn during vehicle storage or transport. *Wheel/Tire change |
| 01-012-21-3832 | 2021-10-31. Service bulletin. Some vehicles may have a LOW ENGINE OIL LEVEL warning message and a CHECK ENGINE light illuminated in the instrument cluster, along with DTC P250F:00 stored in memory. DTC P250F:00 - Engine oil level signal: engine oil level low. Upon inspecting the engine oil level, the level is found to be low and there doesn't appear to be any trace of oil leakage in the engine compartment. This concern usually occurs when the mileage reaches approximately 3,100 - 4,700 miles (5,000 - 7,500km) and may also occur again after replacing or topping off the engine oil. The root cause of this concern has not been identified yet, therefore a repair procedure will be announced at a later date. Since this issue has been reported after a valve stem seal modification, it is very likely that valve stem seal damage is causing oil to leak into the combustion chamber. |
