02-004-22a2022-12-02. Service bulletin. SUSPENSION. Some customers may complain of signs of oil on the struts or shock absorbers. In most cases the oil that is present is normal, and a result of the oil that remains on the shaft during the normal sweeping process of the shaft seal. Follow the inspection guidelines below to determine if the condition is a result of the normal sweeping process or a failure of the shaft seal.
01-010-222022-10-06. Service bulletin. POWER TRAIN. Some customers may experience a squeaking noise may be heard from the exhaust manifold when the idle speed drops from fast idle to normal idle speed during cold start. This is caused by a variable valve being stuck in the closed position. When returning from fast idle to normal, the stuck valve suddenly opens due to thermal change around it which causes abnormal noise. To eliminate this concern, the internal design of the exhaust manifold has been modified.

05-002-21-38542022-01-06. Service bulletin. POWER TRAIN. Automatic Transmission/Transaxle Cooler and Lines Flushing Procedure: Automatic Transaxle/Transmission (A/T) oil cooler and lines must be power flushed completely before an overhauled or replacement A/T is installed (except SKYACTIV-DRIVE). The most common cause of repeat A/T failures is lack of lubrication to the front and rear planetary gears. This is usually caused by an accumulation of metal particles and debris (from a previous A/T failure) on the internal mesh type baffle of the oil cooler. Power flushing will remove the restriction by back flushing, followed by forward flushing to dislodge a restriction, then back flushing again. This will in turn ensure full ATF flow for the transmission when it is operating.

07-001-21-37752021-02-05. Service bulletin. EQUIPMENT. A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. “Mazda Air Cooling Coil Coating” is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years.
