SSPB6c2020-11-04. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. MAZDA CONNECT TOUCH SCREEN CONCERN WARRANTY EXTENSION SPECIAL SERVICE PROGRAM: Mazda Motor Corporation is extending the warranty coverage for a specific concern regarding the Mazda Connect Center Display on certain 2014-2016 Mazda3 vehicles produced from June 11, 2013 through September 3, 2016. Please refer to the Parts and Warranty page for specific production date ranges for MC and MMVO produced vehicles as they are different. Concern Outline: On certain 2014-2016 Mazda3 vehicles, the Mazda Connect touch screen in the center display may not accept touch commands properly or may operate by itself (ghost touch). The ITO (Indium Tin Oxide) film of the touch screen may be corroded due to moisture, which may adhere on the lens of the touch screen during the cleaning process at the plant. The corrosion may allow the electrostatic capacity to vary without any input, causing the malfunction of the touch screen. This warranty extension program applies only to the repair of the center display with this concern.

This noise is a normal engine operation for improved exhaust gas emissions. The noise does not indicate a malfunction. ACCELERATED WARM-UP SYSTEM (AWS): All SKYACTIV-G engines adopt AWS to reduce exhaust gas emissions immediately after a cold engine start. AWS increases the engine idling speed and retards the ignition timing for about 20 seconds after the cold engine start to quickly warm up the catalytic converter. The customer may identify the engine sound during the AWS operation as a unusual noise.
MT-001-202020-08-04. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. If you encounter any type of electrical concern (e.g, dead battery, engine no start, DTC(s) stored...), interview the customer before proceeding with normal Workshop Manual diagnosis. Aftermarket devices may be the cause of the electrical concern. Ask the customer if any aftermarket devices have been installed. Below are a couple of examples of unusual electrical concerns caused by aftermarket devices.

This is caused by inappropriate transmission internal parts.
05-003-20-37252020-08-04. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; POWER TRAIN; EQUIPMENT; ENGINE. Some vehicles may experience the check engine light and automatic transaxle warning light ON with one or more of these DTCs stored in the TCM memory (P0842, P0847, P0872, P0877, P0780, P1738). This is caused by the oil pressure switch A and/or B at the control valve body temporarily or permanently getting stuck due to contamination entering the passage. To correct the problem, some mass production changes have been implemented to reduce contamination and improve the DTC diagnostic logic.
