Subaru reported a programming error in the transmission control unit (TCU) which can cause the trnsmission drive chain to slip.  Consistent slippage and wear of the guide chain could lead to a break resulting in loss of power and increasing risk of a potential crash.  Fragments from the chain guide would inhibit proper operation of the shift select mechanism which means your transmission would be toast!  We don't want that to happen to any of our customers so please continue to read.

Subaru is currently working on supplying their dealers with the parts and tools needed to make the repairs.  Supply chain and global manufacturing issues from the pandemic have slowed this process.  The manufacturer expects some parts and tools to arrive at dealerships sometime in Summer 2022 and repairs could begin in some areas in August of 2022. Subaru Service departments will then be able to analyze your TCU's historical data for signs of chain slippage.  Your chain guide and chain will be visually inspected. The transmission assembly will be replaced at no charge to the customer if the chain guide is damaged and your TCU will be reprogrammed.
