What is the 2015-2021 Subaru WRX Piston Ringland Failure?
The FA20DIT engine can suffer from piston ringland failure, especially when tuned or running high boost. The ringland (area between piston rings) can crack, causing compression loss and engine damage. This is often related to detonation from improper tuning or low octane fuel. Repairs typically run $4,000-$10,000. Severity: high.
What is the 2018-2019 Subaru WRX Denso Low-Pressure Fuel Pump Impeller Deformation Causing Engine Stall (Recall 21V-587)?
2018-2019 WRX vehicles received Denso in-tank low-pressure fuel pumps whose impellers were made at too low a density and over-exposed to a drying agent; the impeller absorbs fuel, swells, and rubs the pump body until the pump slows or seizes. Drivers see a hesitation, rough runni… Repairs typically run $0-$700. Severity: high.
