Service bulletin 16-132-20R

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.

16-141-23R2023-08-02. Service bulletin. This bulletin announces availability of reprogramming files to optimize the Transmission Control Module (TCM). The new files were designed to address cases of DTC P0711 (Transmission Fluid Temperature Sensor “A” Circuit Range/Performance) being detected by the TCM during low ambient temperatures (32° F(0° C)).
16-136-22R2023-07-03. Service bulletin. This service bulletin provides a temporary repair procedure to address vibrations and/or judder concerns experienced on turns during acceleration.
16-140-232023-05-02. Service bulletin. This bulletin announces availability of new reprograming files for the Transmission Control Module (TCM) to address judder a sensation possibly accompanied by a vibration-type sound when accelerating from slow speeds.
16-125-192022-03-04. Service bulletin. This bulletin outlines design changes made to the TR580 CVT oil pan assembly.
16-111-18R2019-03-25. Service bulletin. This bulletin announces reprogramming file availability to optimize the Transmission Control Module (TCM) used with the TR580 CVT. Contamination in a fluid pressure solenoid valve can cause a DTC P0841. The new logic will allow the solenoid to operate in a manner enabling it to discharge the contamination.
16-118-182019-02-25. Service bulletin. This bulletin announces reprogramming file availability to optimize the Transmission Control Module (TCM) for detection of DTC P1518: STARTER SWITCH CIRCUIT LOW. After using the Remote Engine Starter (RES) to start an applicable vehicle equipped with the Auto Start-Stop System, the TCM may mistakenly detect DTC P1518 when the engine automatically restarts and cause the AT TEMP warning lamp to illuminate.
WTT-792018-10-01. Service bulletin. Subaru of America, Inc. has initiated a service program for certain 2017?2019 MY Impreza vehicles, and certain 2018?2019 MY Crosstrek vehicles. This service program involves installation of reprogramming files to optimize the ECM.
WTT-79R2018-10-01. Service bulletin. Subaru of America, Inc. (SOA) is initiating a service program for certain 2017-2019 MY Impreza vehicles, and certain 2018-2019 MY Crosstrek vehicles. This service program involves installation of reprogramming files to optimize the ECM. Subaru has determined that due to an engine programming issue, the affected vehicles may stall when coming to a stop or driving at a low speed (under 15 MPH) when the air conditioning is operating at maximum capacity. Under certain hot weather conditions, when the vehicle?s air conditioning is running at full capacity, the engine programming may not account for the additional load placed on the engine when slowing down or coming to a stop. In some cases, this could cause the engine to stall requiring the driver to immediately restart the vehicle.
16-111-182018-03-13. Service bulletin. This bulletin announces reprogramming file availability to optimize the Transmission Control Module (TCM) used with the TR580 CVT. Contamination in a fluid pressure solenoid valve can cause a DTC P0841. The new logic will allow the solenoid to operate in a manner enabling it to discharge the contamination.
