2019-2020 WRX trims with the Denso low-pressure fuel pump can stall or fail to restart because the pump impeller may deform. Symptoms include intermittent hesitation, loss of power while driving, and rare fuel-spray smell. NHTSA recall 20V392 covers the repair free of charge at dealers; if paid out of pocket, replacement is roughly $600-$1,200.
2019-2021 WRX 6-speed manuals can develop a high-pitched chirp or whirring noise from the transmission when the clutch pedal is pressed, caused by the throw-out or release bearing. The noise may return even after replacement and can progress to grinding, clutch pedal vibration, and clutch system damage. If ignored, the car may need a full clutch assembly replacement, typically $1,100-$2,200 at an independent shop.
2022-2023 WRX FA24 engines have been found with formed-in-place gasket (RTV) debris blocking the oil pickup screen, causing low oil pressure and potential turbo, rod, or bearing failure. Warning signs include low oil-pressure warning, engine ticking or knocking, and turbo lag or whine; severe cases can destroy the engine quickly. Early oil-pan drop and pickup cleaning costs roughly $600-$1,200, while oil-starved engine replacement quotes run $7,000-$10,000+ at dealerships.
