Service bulletins for the 2016 Mazda Mazda3
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.

| 01-011-17-3364a | 2017-10-04. Service bulletin. ENGINE. If a customer brings their vehicles in with DTC P2183:00 stored, repair the vehicle using the following Repair Procedure and Caution. P2183:00: ECT sensor No.2 circuit range/performance problem. This is caused by the ECT sensor No.2 located near the bottom of the radiator getting wet and water entering the part due to insufficient water resistance. To correct this issue, the water resistance of the ECT sensor No.2 has been improved. |

| SSPA2 | 2017-09-14. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM. Mazda Motor Corporation has decided to conduct a Special Service Program (SSP) on certain 2014-2016 Mazda3 vehicles built at the Mexico plant from December 4, 2013 through September 23, 2015. On certain subject Mazda3 vehicles, the concentration of engine coolant filled at the plant may not be appropriate, which could reduce the cooling or heating performance. With the deterioration of cooling performance, the coolant temperature may increase at high engine load, and a warning light (high engine coolant temperature warning light) may flash or illuminate, resulting in the engine possibly overheating. Dealers are to check the concentration of engine coolant, and replace the coolant if necessary. The check and repair must be performed at no charge to the vehicle owner. This campaign expires March 1, 2017. |
| SA-060-17 | 2017-08-10. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE; ENGINE.

If the PCM is reprogrammed with any software number included in the attached file and the throttle valve has too much carbon build up, the engine air amount calculation by the problem software may not be accurate. Perform the following Repair Procedure to correct this issue. NOTE Current version of IDS is 106.02. |
| 01-005-17-3305 | 2017-08-10. Service bulletin. ENGINE AND ENGINE COOLING. Some vehicles may exhibit oil residue on the engine front cover from seepage around the joint portion (A) between the cylinder block and head. It becomes very noticable with dust adhesion. In some cases, the area of oil residue extends down to around the joint portion (B) between the engine front cover and the oil pan. |
| 01-002-17-3299a | 2017-08-10. Service bulletin. ENGINE AND ENGINE COOLING; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. 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. |
| 05-002-15-3019F | 2017-06-08. Service bulletin. ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION. 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). • P0842:00 - OIL PRESSURE SWITCH NO. 1 (OIL PRESSURE SWITCH B) STUCK ON • P0847:00 - OIL PRESSURE SWITCH NO. 2 (OIL PRESSURE SWITCH A) STUCK ON • P0872:00 - OIL PRESSURE SWITCH NO. 3 (OIL PRESSURE SWITCH A) STUCK ON • P0877:00 - OIL PRESSURE SWITCH NO. 4 (OIL PRESSURE SWITCH B) STUCK ON • P0780:00 - GEAR SHIFTING MALFUNCTION • P1738:00 AUTOMATIC TRANSAXLE INTERNAL MALFUNCTION 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.
