What the recall covers

Subaru of America, Inc. (Subaru) is recalling certain 2019-2020 Ascent, 2020 Legacy and Outback vehicles. A programming error in the Transmission Control Unit (TCU) may allow the clutch to engage before the drive chain is completely clamped.

Potential consequence

An improperly secured drive chain may slip and break, causing a loss of drive power and increasing the risk of a crash.

Remedy described by NHTSA

Dealers will reprogram the TCU, inspect TCU data for chain slip, and visually inspect the chain guide. If evidence of chain slippage or damage is found, the transmission will be replaced. Repairs will be performed free of charge. Owner notification letters were mailed August 19, 2022. This recall includes all vehicles previously recalled under 19V-855. Vehicles previously recalled under 19V-855 will need to have the new remedy performed for this recall once available. Owners may contact Subaru customer service at 1-844-373-6614. Subaru's number for this recall is WRK-21.
