Owner Narrative

Engine rod knock at 32,000 miles due to bearing failure causing loss of control of vehicle and sudden loss of power and control. Car was logged to be traveling at 35 mph with normal acceleration at time of failure. Carter Subaru confirmed bearing failure, and fits with the pattern confirmed in 2012-2017 WRX STi engine failure class action settlement, as part in 2018 remains unchanged from 2017 according to mechanics. Head mechanic at dealership confirmed that only car modification (intake) would not cause catastrophic loss of oil leading to bearing failure, and thus it is likely due to engine design that leads to poor oil circulation as a known issue in this EJ25 engine type. Engine components have been inspected by Carter Subaru, and have been made available to Subaru of America, along with images, videos, pictures, receipts, logs, records, computer/ECU data, receipts, tool purchases, and other maintenance and service logs for the car (including prior to ownership). Dealership acknowledges that the car maintenance exceeded the manufacturer recommendation, yet engine still failed even with oil changes done at 3,000 mile intervals... While manual states much higher interval to follow. Engine still failed at increased oil change levels. Problem appeared once engine started knocking, which means the engine has already suffered irreversible engine failure and needs to be replaced, according to Subaru. Subaru of America assigned a customer advocate but has been incommunicado for the duration of the investigation and refuses to answer or even acknowledge that a claim has been opened, as they constantly cite erroneous interactions with the vehicle owner.
