While I appreciate the mechanic's diagnosis, we need to be careful that this is another opinion of a very complex issue that the Toyota/Subaru engineers haven't yet figured out after over 3 months of documented failures.
I do believe this is both a hardware and software issue where once the CEL/SL is triggered, damage may have occured to the various components that are being replaced. That is why I don't believe a straight flash or ECU replacement will be solve everyone's problems...some cars, absolutely (especially pre delivery vehicles).

Good point though it does worry me a little that they haven't figured this out after 3 months.
