Buying Tips for 2021 Subaru BRZ

  • ✓Check the oil level religiously; these engines are sensitive to low oil and can suffer bearing failure if run low.
  • ✓Listen for a "cricket" chirping sound from the engine bay, which is a harmless but annoying fuel pump trait.
  • ✓On 2022+ models, be aware of "RTV" sealant issues in the oil pan which can clog the oil pickup.
