Service bulletins for the 2018 Subaru Forester
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.

| WRB-21 | 2021-03-04. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER. In the interest of customer satisfaction, Subaru of America, Inc. (Subaru) is initiating a service program to check and, if necessary, replace the air conditioning condenser assembly in certain 2017 and 2018 model year Forester vehicles. |
| 10-98-20R | 2020-11-05. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM. This bulletin announces availability of new A/C compressor assemblies designed to address customer concerns of reduced system performance accompanied by a rattling and/or scraping type sound. |
| 15-269-20 | 2020-09-04. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER; ELECTRICAL SYSTEM. In the interest of providing continued customer satisfaction, Subaru of America, Inc. (SOA) is extending the basic New Car Limited Warranty coverage for the Condenser component of the Air Conditioning system on all 2017 and certain 2018 MY Forester model vehicles. |
| 10-96-19 | 2020-01-07. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER. This bulletin announces availability of a new HVAC blower motor unit assemblies developed to address isolated concerns of the blower motor becoming inoperative. If this issues occurs on models with Auto A/C, the blower fan may become totally inoperative. If this issue occurs on models with Manual A/C, the blower fan may operate on high speed only. The root cause of these conditions is water intrusion into the blower motor causing rust and corrosion to develop. Over time, the blower motor may begin to draw more electrical current to operate. if that occurs, the additional draw can cause the related fuse and/ or blower resistor to fail. To address this condition, additional packing has been added to improve sealing of the blower unit case along with development of a new style cabin air filter which also in corporates improved sealing. |
| 15-237-19R | 2019-03-25. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. This bulletin provides a diagnostic procedure for a chattering-type sound originating from the a/c compressor assembly. In the case where a refrigerant leak is identified as coming from the a/c condenser, the level of refrigerant oil may also drop and cause the internal vanes of the compressor to make a chattering-type sound. A new-style A/C condenser has been established with enhanced corrosion resistance. |

| 15-223-18 | 2018-06-18. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. This bulletin outlines design changes made to the Condenser Assembly to help increase productivity during assembly. In addition, the new part utilizes materials with increased anti-corrosion performance. |
| 10-83-15R | 2018-04-02. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. Models with Manual HVAC Systems only. This Service Information bulletin provides precautions to use when removing the HVAC control panel to prevent damaging the blower fan speed switch. When removing the control panel, if the fan speed switch wiring harness is pulled taught or becomes stressed, the switch may be damaged. If the connector (lower) portion of the switch becomes separated from the switch body even slightly (see Fig. 1 on page 2), the HVAC control panel assembly must be replaced. The switch itself is not serviceable. The related instrument panel (IP) wiring harness must also be inspected and replaced if any damage is confirmed. NOTE: For 2012MY Impreza, see TSB 10-78-12, dated 4/18/2012. |
