09-012-14-28912017-04-27. Service bulletin. EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. WHEN REPLACING THE SIRIUSXM SATELLITE RADIO UNIT (OR A MAZDA CONNECT TUNER AND AMP UNIT (TAU)) WITH REPLACEMENT TUNER FOR ANY REASON, A CALL MUST BE MADE TO INFORM SIRIUSXM OF THE EXISTING RADIO ID AND THE NEW/ REPLACEMENT SAT RADIO ID AS SOON AS POSSIBLE TO ENSURE THE CUSTOMER LEAVES THE DEALERSHIP WITH ACTIVE (WORKING SAT RADIO.
01-004-14-28932017-04-27. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. SOME VEHICLES MAY EXPERIENCE THE MIL ON WITH DTC P013A:00 (HO2S CIRCUIT SLOW RESPONSE). THIS IS CAUSED BY IMPROPER CONTROL LOGIC OF THE PCM. TO CORRECT THE PROBLEM, THE CONTROL LOGIC OF THE PCM HAS BEEN CHANGED.
05-002-14-28942017-04-27. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. SOME VEHICLES MAY EXHIBIT THE ATX FAIL-SAFE FUNCTION WORKING WITH THE FOLLOWING SYMPTOMS: • THE VEHICLE SPEED DOES NOT INCREASE WITH ENGINE SPEED • THE ATX DOES NOT SHIFT UP OR DOWN AS EXPECTED. THE CONDITION MAY NOT ALWAYS BE ABLE TO BE REPRODUCED AND DTCS MAY NOT BE STORED WHEN THE VEHICLE IS BROUGHT IN. FOREIGN MATERIAL (IRON PARTICLES IN THE ATF) MAY ENTER THE ATX VALVE BODY AND CAUSE A TEMPORARY MALFUNCTION OF THE VALVE BODY AND/OR SENSOR (ATX FAIL-SAFE FUNCTION ACTIVATED). THE FAIL-SAFE FUNCTION IS CANCELED WITHOUT DTCS RECORDED IF THE MALFUNCTION GOES AWAY AND DOES NOT OCCUR AGAIN AT THE NEXT DRIVE CYCLE. FAIL-SAFE FUNCTION OPERATION: • IF A TECHNICAL FAULT IS DETECTED IN THE ATX BY THE MALFUNCTION DETECTION FUNCTION, THE FAIL-SAFE FUNCTION LIMITS THE ATX CONTROL (INHIBITS SOME GEARS OR SHIFT DOWN FUNCTIONS). • EVEN IN CASE OF AN ATX MALFUNCTION, THE FAIL-SAFE FUNCTION ALLOWS MINIMUM VEHICLE DRIVEABILITY.
05-003-14-28982017-04-27. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. SOME VEHICLES MAY EXPERIENCE THE MIL ON WITH DTC P0780 (GEAR SHIFTING MALFUNCTION) AND/OR P1738 (AUTOMATIC TRANSAXLE INTERNAL MALFUNCTION) WITH/WITHOUT U0401, OR OTHER DTCS STORED IN MEMORY. OTHER DTCS (WITH THE ABOVE DTCS) - P0746:00, P0751:00, P0752:00, P0756:00, P0757:00, P0761:00, P0762:00, P0766:00, P0767:00, P0771:00, P0772:00, P079A:00, P0842:00, P0843:00, P0847:00, P0848:00, P0872:00, P0873:00, P0877:00, P0878:00, P1784:00 TO CORRECT THE PROBLEM, A NEW PROGRAMMED VALVE BODY HAS BEEN ESTABLISHED.

04-002-14-28792017-04-27. Service bulletin. SERVICE BRAKES, AIR:ANTILOCK:ABS WARNING LIGHT. SOME CUSTOMERS MAY REPORT A SLIGHT CLUNK/BANG/BUZZ NOISE OR JOLT FROM THE FRONT OF THE VEHICLE. THIS CONCERN WILL MOST LIKELY OCCUR DURING THE VEHICLES FIRST FORWARD MOVEMENT AFTER STARTING THE ENGINE. THIS IS A NORMAL OPERATING NOISE OF THE ANTI-LOCK BRAKE SYSTEM (ABS). DO NOT ATTEMPT ANY REPAIRS.
09-007-14-28782017-04-26. Service bulletin. EXTERIOR LIGHTING:FOG LIGHTS. SOME CUSTOMERS MAY COMPLAIN OF CONDENSATION/FOG INSIDE THE FRONT OR REAR COMBINATION LIGHTS. THE RECENT NEW MODELS HAVE BEEN FITTED WITH A CLEAR LENS WHICH CAN CAUSE THE SYMPTOM TO BE MORE NOTICEABLE, HOWEVER, IT DOES NOT AFFECT THE PERFORMANCE OF THE LIGHT. THIS CONDENSATION/FOG IS A NATURAL PHENOMENON THAT OCCURS WHEN THERE IS A FAIRLY LARGE TEMPERATURE DIFFERENCE BETWEEN THE INSIDE AND THE OUTSIDE OF THE LIGHT HOUSING. IT IS NORMAL FOR VERY SMALL WATER DROPS TO APPEAR IN CERTAIN LOCATIONS ON THE LIGHT UNITS WHERE THE AIR IS STAGNANT (CONDENSATION), MAKING THE LENS LOOK WHITISH (FOG). THIS HAPPENS MOSTLY IN THE CORNERS AND NARROW SPACES, AND WILL TYPICALLY CLEAR DURING WARMER AMBIENT TEMPERATURES, OR WHEN THE LIGHTS HAVE BEEN ON FOR SOME TIME. EXPLAIN TO THE CUSTOMER THAT THIS IS A NATURAL PHENOMENON AND NOT A QUALITY DEFECT. DO NOT ATTEMPT REPAIRS AS THIS IS CONSIDERED NORMAL, AND IS NOT COVERED UNDER WARRANTY. REPLACING THE LIGHT UNIT WILL NOT CORRECT THIS SYMPTOM.
05-005-13-2735B2017-04-26. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:GEAR POSITION INDICATION (PRNDL). SOME VEHICLES MAY EXPERIENCE THE MIL ON WITH DTC P0780 (GEAR SHIFTING MALFUNCTION) AND/OR P1738 (AUTO-MATIC TRANSAXLE INTERNAL MALFUNCTION) WITH/WITHOUT U0401, OR OTHER DTCS STORED IN MEMORY.OTHER DTCS (WITH THE ABOVE DTCS) - P0746:00, P0751:00, P0752:00, P0756:00, P0757:00, P0761:00, P0762:00, P0766:00, P0767:00, P0771:00, P0772:00, P079A:00, P0842:00, P0843:00, P0847:00, P0848:00, P0872:00, P0873:00, P0877:00, P0878:00, P1784:00TO CORRECT THE PROBLEM, A NEW PROGRAMMED VALVE BODY HAS BEEN ESTABLISHED.

09-034-12-2708A2017-04-26. Service bulletin. INTERIOR LIGHTING. SOME VEHICLES MAY EXHIBIT A NOISE FROM THE MAP LIGHT (A) WHILE DRIVING OR AT IDLE. THIS IS CAUSED BY ONE OF TWO THINGS. 1. EXCESSIVE CLEARANCE BETWEEN THE MAP LIGHT AND LAMP UNIT POSITIONING RIB (FOR MAZDA3 VEHICLES WITH VINS LOWER THAN JM1BL******144839 / PRODUCED BEFORE APRIL 1, 2009). THE DESIGN OF THIS RIB HAS NOW BEEN CHANGED TO CORRECT THIS PROBLEM. 2. THE OVERHEAD CONSOLE BRACKET VIBRATES AND CONTACTS THE ROOF PANEL (FOR MAZDA3 VEHICLES WITH VINS JM1BL******144839 TO JM1BL******707082 / PRODUCED AFTER APRIL 1, 2009 AND BEFORE AUGUST 8, 2012. THE NOISE OCCURS ON VEHICLES THAT HAVE A NON-WOVEN TEXTILE ATTACHED AT THE FRONT STAY. THE MATERIAL OF THE PADS HAS NOW BEEN CHANGED TO CORRECT THIS PROBLEM.
