A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

| 01-014-15-3055 | 2017-05-17. Service bulletin. ENGINE. FREQUENT ENGINE STARTS UNDER EXTREMELY COLD AMBIENT TEMPERATURES MAY RESULT IN OIL SEEPAGE FROM THE ENGINE OIL PRESSURE SWITCH. THIS CONCERN MAY BE CAUSED BY A LACK OF DURABILITY OF THE OIL PRESSURE SWITCH UNDER THESE CONDITIONS. TO CORRECT THE PROBLEM, THE OIL PRESSURE SWITCH HAS BEEN IMPROVED TO INCREASE THE DURABILITY IN COLD AMBIENT TEMPERATURES. ALL SKYACTIV ENGINES EQUIPPED WITH OIL PRESSURE SWITCH PART NUMBER PE01-18-501A ARE APPLICABLE TO THIS ISSUE. |

| 01-009-14-2909A | 2017-05-08. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. SOME VEHICLES MAY EXPERIENCE A ROUGH IDLE WITH THE MIL ON AND DTC P0015 / P0524 STORED IN MEMORY.•P0015:00 - EXHAUST CMP TIMING OVER-RETARDED•P0524:00 - ENGINE OIL PRESSURE TOO LOWTHIS IS CAUSED BY A DROP IN ENGINE OIL PRESSURE DUE TO A PIECE OF FOREIGN OBJECT STUCK ON THE OIL PUMP PRESSURE RELIEF VALVE OR OCV. THE TEMPORARY ENTRY OF THE FOREIGN OBJECT TRIGGERS A MIL ILLUMINATION, BUT ROUGH IDLE WILL NOT BE PRODUCED UNTIL A LATER TIME. |
| 05-008-13-2861 | 2017-04-26. Service bulletin. ENGINE. 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 EXPECTEDTHE 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. |
| 01-023-13-2834 | 2017-04-24. Service bulletin. ENGINE. SOME VEHICLES MAY EXHIBIT AN ENGINE NO START IN AMBIENT TEMPERATURES BELOW -4 DEGREE FAHRENHEIT (-20 DEGREE CELSIUS) AFTER DRIVING FOR 10 - 20 MINUTES AND THEN PARKING THE CAR FOR ABOUT ONE HOUR. THIS MAY BE CAUSED BY THE CONTACT POINT OF THE MAIN RELAY FREEZING DUE TO MOISTURE INSIDE THE MAIN RELAY. |
| 01-006-13-2765 | 2017-04-13. Service bulletin. ENGINE. SOME CUSTOMERS MAY COMPLAIN ABOUT AN UNUSUAL NOISE COMING FROM THE ENGINE COMPARTMENT FOR ABOUT 20 SEC-ONDS AFTER A COLD ENGINE START. THIS NOISE IS A NORMAL ENGINE OPERATION FOR IMPROVED EXHAUST GAS EMISSIONS. THE NOISE DOES NOT INDICATE A MALFUNCTION. |
| 01-001-13-2746A | 2017-04-13. Service bulletin. ENGINE. SOME VEHICLES MAY EXPERIENCE MIL ILLUMINATION WITH DTC P2610 (INSTRUMENT CLUSTER INTERNAL ENGINE OFF TIMER PERFORMANCE PROBLEM) STORED IN MEMORY AFTER ENGINE START AND ROOM FUSE 15A (A) REMOVED. |
| 01-009-16-3172A | 2017-02-28. Service bulletin. ENGINE. SOME VEHICLES MAY EXPERIENCE A ROUGH IDLE WITH THE CHECK ENGINE LIGHT ON AND DTC P0015 / P0524 STORED IN MEMORY.•P0015:00 - EXHAUST CMP TIMING OVER-RETARDED•P0524:00 - ENGINE OIL PRESSURE TOO LOWTHIS IS CAUSED BY A DROP IN ENGINE OIL PRESSURE DUE TO A PIECE OF FOREIGN OBJECT STUCK ON THE OIL PUMP PRESSURE RELIEF VALVE OR OIL CONTROL VALVE (OCV). THE TEMPORARY ENTRY OF THE FOREIGN OBJECT TRIGGERS A CHECK ENGINE LIGHT ON, BUT ROUGH IDLE WILL NOT BE PRODUCED UNTIL A LATER TIME. |
| 01-011-16-3139 | 2017-02-28. Service bulletin. ENGINE. SOME VEHICLES MAY EXPERIENCE A ROUGH IDLE WITH THE CHECK ENGINE LIGHT ON AND DTC P0015 / P0524 STORED IN MEMORY.•P0015:00 - EXHAUST CMP TIMING OVER-RETARDED•P0524:00 - ENGINE OIL PRESSURE TOO LOWTHIS IS CAUSED BY A DROP IN ENGINE OIL PRESSURE DUE TO A PIECE OF FOREIGN OBJECT STUCK ON THE OIL PUMP PRESSURE RELIEF VALVE OR OIL CONTROL VALVE (OCV). THE TEMPORARY ENTRY OF THE FOREIGN OBJECT TRIGGERS A CHECK ENGINE LIGHT ON, BUT ROUGH IDLE WILL NOT BE PRODUCED UNTIL A LATER TIME. |
| 01-010-16-3185 | 2017-02-28. Service bulletin. ENGINE. SOME VEHICLES MAY EXPERIENCE THE CHECK ENGINE LIGHT ON WITH DTC P0421:00 (CATALYTIC CONVERTER SYSTEM) WITH-OUT EXPERIENCING POOR ENGINE PERFORMANCE OR MISFIRE (MITSUBISHI PCM ONLY).THIS IS CAUSED BY IMPROPER CONTROL LOGIC OF THE PCM THAT MAY DETECT FALSE ERROR OF THE A/F SENSOR, RESULTING IN FALSE DETECTION OF P0421. TO CORRECT THE PROBLEM, THE CONTROL LOGIC OF THE PCM HAS BEEN CHANGED.CATALYST MON-ITOR FUNCTION EXPLANATION•THE PCM MONITORS THE OXYGEN STORAGE AMOUNT PROPORTIONAL TO CATALYTIC CONVERTER PURIFICATION CHARACTERISTIC.•THE PCM STARTS TO MONITOR AFTER RECOVERY (FUEL INJECTION STARTS) FROM FUEL CUT CONTROL.•THE PCM TEMPORARILY CHANGES THE TARGET AIR/FUEL RATIO TO RICH AT FUEL CUT RECOVERY, AND DETECTS THE RESPONSE TIME UNTIL THE HO2S OUTPUT SIGNAL OUTPUTS THE VOLTAGE ON THE RICH SIDE. IF THE CATALYTIC CONVERTER PURIFICATION CHARACTERISTIC DETERIORATES, THE AMOUNT OF THE TIME UNTIL THE HO2S DETECTS THE VOLTAGE ON THE RICH SIDE IS SHORTER COMPARED TO THE NORMAL PURIFICATION CHARACTERISTIC AS SHOWN. THE PCM DETECTS A CATALYTIC CONVERTER MALFUNCTION USING THIS CHARACTERISTIC. |
| 01-011-16-3139A | 2017-02-24. Service bulletin. ENGINE. WHEN THE ENGINE IS STARTED FOR THE FIRST TIME AFTER PARKING THE VEHICLE OVERNIGHT IN COLD CONDITIONS (BELOW 32 DEGREES FAHRENHEIT / 0 DEGREES CELSIUS), SOME VEHICLES MAY EXHIBIT A ROUGH IDLE AND/OR THE CHECK ENGINE LIGHT ON WITH ANY OF THE FOLLOWING DTC(S) STORED IN MEMORY.•P0300 - RANDOM MISFIRE DETECTED•P0301 - CYLINDER NO.1 MISFIRE DETECTED•P0302 - CYLINDER NO.2 MISFIRE DETECTED •P0303 - CYLINDER NO.3 MISFIRE DETECTED •P0304 - CYLINDER NO.4 MISFIRE DETECTED THIS MAY BE CAUSED BY FROZEN WATER ACCUMULATED IN THE MAIN SILENCER, RESTRICTING EXHAUST FLOW. |
| 01-009-16-3172B | 2017-02-24. Service bulletin. ENGINE. SOME VEHICLES MAY EXPERIENCE A ROUGH IDLE WITH THE CHECK ENGINE LIGHT ON AND DTC P0015 / P0524 STORED IN MEMORY.•P0015:00 - EXHAUST CMP TIMING OVER-RETARDED•P0524:00 - ENGINE OIL PRESSURE TOO LOWTHIS IS CAUSED BY A DROP IN ENGINE OIL PRESSURE DUE TO A PIECE OF FOREIGN OBJECT STUCK ON THE OIL PUMP PRESSURE RELIEF VALVE OR OIL CONTROL VALVE (OCV). THE TEMPORARY ENTRY OF THE FOREIGN OBJECT TRIGGERS A CHECK ENGINE LIGHT ON, BUT ROUGH IDLE WILL NOT BE PRODUCED UNTIL A LATER TIME. |
| 1080M | 2017-02-23. Service bulletin. ENGINE. 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.CLEAN THE INTAKE MANIFOLD INTERNALLY TO REMOVE ANY DEBRIS FROM OLD ENGINE BEFORE INSTALLING THE NEW REPLACEMENT ENGINE ASSEMBLY.IF THE INTAKE MANIFOLD CANNOT BE PROPERLY CLEANED INTERNALLY, REPLACE IT. |
