09-004-18-3402a2018-03-05. Service bulletin. STRUCTURE:BODY:DOOR. Some customers may complain that the door weatherstrip (1) comes off at the front / lower part of the reardoor(s). This concern is caused by insufficient weatherstrip gripping force.
01-001-18-34192018-03-05. Service bulletin. ELECTRICAL SYSTEM. After parking the vehicle at temperatures below the freezing, some customers may experience a lack of power with the check engine light on and DTC P0638:00 and/or P2112:00 stored in memory. - P0638:00: Throttle valve actuator control range/performance problem (one drive cycle DTC) - P2112:00: Throttle valve actuator motor currentrange/performance problem (one drive cycle DTC) This concern may be caused by condensed water in the intake manifold entering the throttle valve. After parking at temperatures below freezing, the throttle valve may be frozen at the stand-by position, resulting in the symptom. To prevent this concern, the control logic of the PCM has been modified to avoid frozen the throttle valve (by moving the valve at a certain time after the ignition has been turned off). NOTE: With this modification, the main relay may stay on up to 90 minutes after the ignition switch is turned off. "BATTERY INSPECTION" in the Workshop Manual will be modified to properly check the battery parasitic draw after this modification.
09-004-18-34022018-03-05. Service bulletin. STRUCTURE:BODY:DOOR. Some customers may complain that the door weatherstrip (1) comes off at the front / lower part of the reardoor(s). This concern is caused by insufficient weatherstrip gripping force.

SA-074-172018-02-26. Service bulletin. ELECTRICAL SYSTEM. If the BSM control module is replaced, Auto Configuration and BSM Radar Test must be performed: 1. Auto Configuration -When the ignition is switched ON, the blind spot monitoring (BSM) reads the vehicle specification information sent via CAN communication from the instrument cluster, and stores the vehicle specification information into the new BSM control module. 2. BSM Radar Test - This test confirms correct BSM module/bracket alignment. The Workshop Manual "BLIND SPOT MONITORING (BSM) RADAR TEST" is incorrect. Mazda is in the process of correcting the error. Perform the following procedure temporarily until the Workshop Manual is corrected:
01-009-17-3377a2018-02-26. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). Some customers may experience a lack of power when driving. The master warning light or the check engine light turns on and DTC P130C:00 and U0401:00 (ABS) stored in memory. It occurs mostly at low temperatures. Once the ignition is turned off and on, the concern may disappear. NOTE: DTC P130C:00 may not be found upon M-MDS self test since this DTC is detected when the condition occurs in two drive cycles in a row. The PCM turns the master warning light on during the first drive cycle, then stores a pending DTC. The master warning light and check engine light come on in the second drive cycle as a confirmation of the DTC. The engine power is limited by the fail-safe function both in the first and second drive cycles. DTC P130C:00 - (Pre-ignition detected), DTC U0401:00- (ABS) (Signal error from PCM) Improper control logic of the PCM detects a normal operating noise as a knocking noise. To eliminate this concern, the control logic of the PCM has been changed.
06-001-17-3307b2018-02-26. Service bulletin. STEERING: STEERING WHEEL/HANDLE BAR. 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.
02-007-17-3337b2018-02-26. Service bulletin. POWER TRAIN; SUSPENSION. Some vehicles may exhibit one or more of the following noises from the front suspension: 1. A creaking noise from under the front of the vehicle (front lower arm bushing) when driving over bumps atapproximate 12 - 25 mph (20 - 40 Km/h). The noise occurs when the road surface is wet or after the vehicle has been washed. The noise becomes more noticeable as the bumps get higher. The creaking noise is caused by the front lower arm bushing (A) making a stick-slip noise during wet road conditions. 2. A clunking noise from the front coil spring when driving over bumps. The clunking noise is due to stick-slip between the front strut bearing (B) and the coil spring (C). 3. A popping noise from the bump stopper (D) when driving through gutters. To eliminate the noise, the following mass-production changes have been made: 1. The coating treatment of the lower arm bushing has been changed to reduce friction and prevent stick-slip. 2. Protectors have been installed onto the coil springs to prevent stick-slip. 3. No mass-production change is scheduled for the bump stopper, however, a modified service part has been established.
MT-016-172017-12-14. Service bulletin. FORWARD COLLISION AVOIDANCE: SENSING SYSTEM. The Smart City Brake Support (SCBS) system alerts the driver of a possible collision using an indication in the display and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle ahead and determines that a collision with a vehicle ahead is imminent. In addition, the system reduces damage in the event of a collision by operating the brake control when the system determines that a collision is unavoidable. It may also be possible to avoid a collision depending on the relative speed between your vehicle and the vehicle in front of you. In addition, when the driver depresses the brake pedal, the brakes are applied firmly and quickly to assist.
15-005-17-3358b2017-11-14. Service bulletin. ELECTRICAL SYSTEM; EXTERIOR LIGHTING. Some customers may complain that the BSM indicator light on the outer mirror glass does not illuminate when: ?
