NHTSA's recall notice
As NHTSA's recall record states it for campaign 19V855000.
Defect description
Subaru of America, Inc. (Subaru) is recalling certain 2019 Ascent vehicles. The transmission hydraulic sensor may inaccurately measure the hydraulic fluid pressure.
Safety consequence
If the fluid pressure is measured higher than its actual value, the hydraulic pressure will be reduced. If this occurs, the transmission drive chain may not have the proper tension, resulting in a loss of drive power and an increased risk of a crash.
Manufacturer remedy
Subaru will notify owners, and dealers will reprogram the transmission control unit. The hydraulic sensor harness will be replaced on vehicles with certain stored diagnostic trouble codes. In addition, any vehicle confirmed to have experienced low drive chain tension will have the transmission assembly will be replaced. All repairs will be free of charge. The recall began January 31, 2020. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WUV-07.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
