Subaru of America is recalling 198,255 model year 2019-2020 Ascents, and model year 2020 Legacys and Outbacks.
A programming error in the Transmission Control Unit (TCU) may allow the clutch to engage before the drive chain is completely clamped.
An improperly secured drive chain may slip and break, causing a loss of drive power and increasing the risk of a crash.
What to do
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.
Interim owner notification letters are expected to be mailed on February 7, 2022. The remedy is expected to be available in April 2022.
Owners may contact Subaru customer service at (844) 373-6614. Subaru's number for this recall is WRK-21.
