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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10154422-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10154422-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10154422","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"hvac","name":"Heating and air conditioning","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"SUBARU","model":"FORESTER","year_from":2017,"year_to":2018,"match":"exact","vehicle_ids":["2017_subaru_forester","2018_subaru_forester"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
