Subaru did not notify consumers or aftermarket retailers that the Subaru battery in my vehicle was underamped. As a result, I unknowingly bought an underamped battery from Autozone to replace my dying battery in 2024, b/c their records indicated it was the right battery. I found out in 3/25 from Subaru service about the underamped battery issue when my car was dying. Autozone cant replace it because their system (info they get from Subaru) says this is the right battery, because Subaru didnt notify anyone. Subaru will not replace the battery for free because its not a Subaru battery. I have an internal service memo from 2023 that states what the right battery should be. However, Subaru didnt notify the public or companies and so several people are probably driving around with underamped aftermarket batteries. I should not have to pay for a new battery, I should have received notice in 2023 about this issue and then I would have replaced it with the right Subaru battery. The battery I replaced in 2024 was the original Subaru underamped battery.
