MT-002-192019-12-20. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT. If an engine assembly is replaced after a catastrophic internal mechanical failure, clean the intake manifold internally before installing a replacement engine assembly. If the intake manifold is not cleaned properly, the replacement engine may fail prematurely. Metallic debris from the old engine (with catastrophic internal mechanical failure) may rest inside the intake manifold. When the new engine assembly is installed, debris in the intake manifold will be ingested into the new engine and cause internal damage.
07-002-19-3616a2019-12-20. Service bulletin. EQUIPMENT; EQUIPMENT:APPLIANCE:AIR CONDITIONER; EQUIPMENT ADAPTIVE/MOBILITY. 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. NOTE: See parts information for Mazda Air Cooling Coil Coating and Kit part numbers.
01-022-19-36572019-12-20. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT; ENGINE AND ENGINE COOLING. There is a concern that some water pumps are being replaced that are not faulty, due to signs of a very small coolant leak from the bleed hole. This Service Bulletin is to inform you about the water pump sealing mechanism and the criteria if replacement is necessary or not.
MT-004-192019-11-24. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT; ELECTRICAL SYSTEM. Some customers may complain about: • Intermittent engine no start • Instrument cluster red security indicator light ON • Engine Start/Start Button Amber indicator light flashing • Battery discharge • Electrical relay buzzing noise • DTC B13D3:94 (Communication error with remote transmitter) stored.This may be caused by: • A key in a purse near a cell phone. The cell phone radio waves may interrupt the immobilizer system. • An aftermarket cell phone charger. The charger may produce electrical noise that interrupts the immobilizer system. • An aftermarket GPS tracker. Some aftermarket devices that are wired to the vehicles’s wiring harness may create unusual electrical symptoms.
SA-049-192019-11-21. Service bulletin. EQUIPMENT; ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM. Some customers may complain about a Mazda Mobile Start (MMS) system malfunction. Use the information below to troubleshoot the customers complaint: • MAZDA MOBILE START (MMS) TROUBLESHOOTING GUIDE • CANNOT COMMUNICATE WITH VEHICLE • ERROR MESSAGE INSTALLED ON ANDROID DEVICES • COMMUNICATION ERRORS • MMS CHECK MODE - Use to verify system operation (see below).
SA-048-192019-11-21. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; EQUIPMENT. Some customers may expierience one or more of the following: • intermittent no start • engine stall • many DTC's stored • no communication with the PCM.

01-017-19-36012019-11-21. Service bulletin. ENGINE AND ENGINE COOLING; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. Some customers may complain about a vibration through the driver and passenger seats at idle in (D)rive and (R)everse when the engine rpm drops down to 550. This vibration is caused by: 1.5L The No.3 and No.4 engine mount rubber hardening during vehicle usage at high ambient temperatures which decreases the damping force. 2.0L Components of the No.3 engine mount rubber melting inside the mount at high ambient temperatures which creates deposits on the engine mount plate that restrict engine mount plate movement. Mass production change has not been determined at this time, but modified No.3 and No.4 engine mounts have been newly established as service parts. Their material and spring characteristic have been changed.
07-007-19-36382019-11-21. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM; ENGINE. Some customers may complain about poor heater performance even after the engine reaches normal operating temperature. This may be caused by a plugged heater core. For 2014-2016 Mazda6 and 2013-2016 (US spec) / 2017 (Mexico spec) CX-5, the CHECK ENGINE light may turn on with DTC P011A:00 (ECT sensor No.1/No.2 performance problem) stored at the same time. NOTE: Refer to TSB 01-015/15 if the customer is using a block heater at temperatures below freezing. To solve this concern, two mass production changes have been implemented. a) The concentration of the coolant has been increased so that the amount of the contained anti-rust additive is higher. b) The composition of the coolant has been changed (the ratio of the anti-rust additive has increased).
SSPB6b2019-11-01. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ELECTRICAL SYSTEM. For certain 2014-2016 Mazda3 vehicles, the warranty coverage for specific repair of the Mazda Connect Center Display is extended to 7 years (84 months) from the original warranty start date, with no mileage limitation. 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 touch screen may be corroded due to moisture, which may adhere on the lens of 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 touch screen.
