Service bulletins for the 2015 Subaru WRX
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.

| 07-146-19 | 2019-03-11. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:WIRING. This bulletin announces a design change made to the engine wiring harness to improve resistance to moisture. A detailed illustration describing the change is supplied below. |
|---|---|
| 17-17-13R | 2019-03-11. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; AIR BAGS. This Bulletin provides information regarding Event Data Recorder (EDR) functionality which has been incorporated into the airbag system. |
| 16-103-16R | 2019-03-11. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. This bulletin has been developed in response to a small number of customer concerns regarding fluid seepage found coming from the CVT assembly. Investigation has identified a likely source of the seepage to be the sealant used on the CVT?s oil pump chain cover. The repair involves removal, a thorough cleaning and inspection of the sealing surfaces followed by re-sealing the cover. |
| 07-133-18 | 2019-02-19. Service bulletin. ENGINE. This Service Information Bulletin announces design changes to the engine?s knock sensor which will help improve vehicle assembly line efficiency and increase durability. In some cases, the Check Engine light may illuminate and a knock sensor-related DTC set in the ECM memory: P0327, P0328, P0332 and P0333. The knock sensor for DIT engines is now utilized for NA engines to improve durability and resistance to heat. |
| 16-112-18R | 2019-02-19. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:IGNITION. This bulletin announces a design change to the CVT select lever (shifter) mechanism in response to isolated customer concerns of not being able to remove the key from the ignition switch when the vehicle is in Park. The cause is contamination of the Park-Range switch internal components. |
| 03-82-18 | 2018-12-10. Service bulletin. EQUIPMENT; EQUIPMENT ADAPTIVE/MOBILITY; POWER TRAIN. This Service Information bulletin announces a design change to the clutch release bearing used on the models as listed above. During assembly of the bearing, a different type of grease is used which has a higher resistance to heat. In cases where the operator keeps a foot on the clutch pedal for extended periods, an increased amount of heat is generated which can cause the grease inside the bearing to deteriorate. In a case of prolonged clutch pedal application, seizure of the bearing can occur with potential damage to other related components. |
| 03-79-18R | 2018-12-10. Service bulletin. POWER TRAIN:CLUTCH ASSEMBLY:PEDAL/HAND LEVER(MOTORCYCLE); EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT. This bulletin announces a change to the clutch system components optimizing their durability and resistance to certain severe driving conditions including high-temperature operation. |
| 06-66-18 | 2018-12-10. Service bulletin. SERVICE BRAKES, HYDRAULIC; SERVICE BRAKES, AIR:DISC:ROTOR; SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:DISC:ROTOR. This Service Information bulletin announces a design change made to the front brake rotors used on the models listed above. The change makes it easier to identify these parts from those used on other models. |
| 02-179-18 | 2018-12-10. Service bulletin. EQUIPMENT ADAPTIVE/MOBILITY; ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER. This Service Information Bulletin announces a change to the procedure and sequence used for torqueing the cylinder head bolts on the EJ25 turbocharged engine used in the 2015-2018MY STI. |
| 12-251-18 | 2018-12-10. Service bulletin. LATCHES/LOCKS/LINKAGES; STRUCTURE:BODY. This bulletin provides a service procedure to address a gap between the top edge of the door and the instrument panel on the models listed as shown in the photo below. The gap may also make the glove box door difficult to close fully.There is a latch to keep the glove box closed on both sides of the glove box door. If the door is closed without using enough force to engage both latches or by pushing it shut on just one side instead of in the middle, one may close and not the other. Over time, if the door is not fully closed with both latches, high cabin temperatures along with weight of the items inside the glove box may cause the assembly to deform slightly and a gap to develop. |
| 03-82-18 | 2018-12-10. Service bulletin. POWER TRAIN; EQUIPMENT ADAPTIVE/MOBILITY. This Service Information bulletin announces a design change to the clutch release bearing used on the models as listed above.

| 07-139-18R | 2018-10-01. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS. This bulletin outlines a design change made to the inner lens extension portion of the LED headlamp assembly. Under the right conditions, the shape of the lens for the actual head lamp light source can cause sunlight to be focused onto the extension portion of the lens resulting in deformation. A heatresistant shade has been added to protect the affected area. |
| 12-234-18 | 2018-08-20. Service bulletin. VISIBILITY:WINDSHIELD.

| 06-63-18R | 2018-08-20. Service bulletin. ELECTRICAL SYSTEM. This bulletin announces a design change to the EPB adapter cord harness connector. In some cases, the retaining tab of the connector may become damaged as a result of removal or installation for diagnosis and later and cause DTC C1956 or C1957 to set and the brake warning lamp to illuminate. The retaining tab portion of the connector has been changed to improve its durability and prevent recurrence of the DTC. If there is no prior history of disconnection and the connector lock tab is not damaged, check for another possible cause for these DTCs. |
| 16-112-18R | 2018-07-16. Service bulletin. ELECTRICAL SYSTEM. This bulletin announces a design change to the CVT select lever (shifter) mechanism in response to isolated customer concerns of not being able to remove the key from the ignition switch when the vehicle is in Park. The cause is contamination of the Park-Range switch internal components. |
| 12-243-18 | 2018-07-16. Service bulletin. STRUCTURE. This bulletin replaces TSB 12-201-16R and provides a new repair procedure to address customer concerns of the hood scoop scrubbing the finish of the hood panel in the areas shown in the photo. Due to different expansion rates between the metal hood panel and the resin material used for the hood scoop, the edges of the scoop?s rear corners may come in contact with the hood panel and abrade the finish. |
