(Subaru) is recalling certain 2019 model year Ascent vehicles in which midjoint of the transmission hydraulic sensor harness was made with dissimilar materials (tinplate and copper) which may cause an oxide film to form. If an oxide film forms, the electrical resistance may increase, potentially causing an incorrect measurement of the hydraulic pressure. If the fluid pressure is measured higher than its actual value, the Transmission Control Unit (TCU) programming was not robust enough to compensate for variation and would instruct the valve to lower the hydraulic pressure, thus potentially reducing the tension on the drive chain. Customers may experience irregular noise and/or vibration while driving, and/or warning lamp illumination. A total of 76,842 U.S. vehicles will be affected by this recall.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10183698-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10183698-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10183698","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"SUBARU","model":"ASCENT","year_from":2019,"year_to":2019,"match":"exact","vehicle_ids":["2019_subaru_ascent"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
