Open the full vehicle complaint log (all categories)I own a 2024 Subaru Impreza (base trim, FB24 engine). The engine has developed repeated oil leaks into the spark plug wells due to failed spark plug tube seals / valve cover sealing on the same engine. The first occurrence was around 24,000 miles. The dealer found engine oil in the spark plug tubes, diagnosed leaking spark plug tube seals (and/or valve cover gasket), and performed repairs under warranty. At that time, the car was relatively new and maintained on schedule. The second occurrence happened again around 30,000 miles. The dealer again found oil in the spark plug tubes, indicating repeat failure of the same type of seals on this low‑mileage engine. This has already happened twice within approximately 6,000 miles on a 2024 vehicle. Oil in the spark plug tubes can cause misfires, rough running, and potential damage to ignition coils and the catalytic converter. It also raises concerns about stalling or loss of power if the misfires worsen while driving. I am concerned that this may be a systemic defect in the FB‑series engines used in late‑model Subaru vehicles, not normal wear. I am requesting that NHTSA track this issue as a potential safety‑related defect involving engine sealing components (spark plug tube seals / valve cover gaskets) that allow engine oil to leak into the spark plug wells on 2024 Subaru Impreza models at low mileage.
