Our known issues database covers the 2002-2025 Subaru WRX with 31 documented issues documented across 6,380+ owner reports.
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.
On GD-chassis WRX models, repeated clutch pedal loads can crack the firewall around the clutch master cylinder and pedal bracket mounting area. Owners report the pedal assembly moving, popping noises from the firewall, inconsistent clutch engagement, and difficulty selecting gear… Repairs typically run $400-$1,800. Severity: high.
A 2013 service summary in the trade publication Vehicle Service Pros describes a small mesh filter inside the banjo bolt that holds the turbocharger oil-supply pipe to the rear of the right-side cylinder head. It says the filter may become clogged, cutting off oil to the turbo an… Severity: high.
NHTSA safety recall 23V-754 (Subaru campaign WRP-23) covers front drive-shaft (half-shaft) assemblies whose CV-joint outer race may crack. A hole in a cooling-water pipe on the supplier's heat-treat line reduced cooling-water flow, improperly cooling the inner surface of the race… Repairs typically run $0-$900. Severity: high.
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.
On 2002-2003 Impreza WRX (EJ205), the connection between a metal fuel delivery line and a rubber hose under the intake manifold can seep fuel during initial cold start in very low ambient temperatures, producing a strong raw-fuel smell in the cabin and engine bay and a fire risk. Repairs typically run $0-$500. Severity: high.
Owners on WRX and STI forums report the factory oil pump pickup tube in the oil pan cracking at its base or at a brazed joint. Owners describe a cracked pickup letting the oil pump suck air instead of oil, which can starve the engine of oil. Applies to: Turbocharged 2.5-liter EJ2… Severity: high.
Corrosion can perforate center or rear brake lines, allowing brake fluid to leak and increasing stopping distance and crash risk. Applies to: Certain 2010 Subaru Impreza WRX vehicles in Canada covered by Transport Canada recall 2014586 (Subaru WQK-47). Vehicles sold in the US are… Severity: high.
The front passenger air bag uses a Takata-sourced, non-desiccated inflator containing phase-stabilized ammonium nitrate. After long exposure to heat, humidity and temperature cycling, the propellant can degrade and the inflator can rupture when the air bag deploys in a crash. Met… Severity: high.
The FA20DIT engine can consume oil at a rate higher than expected, sometimes up to 1 quart every 1,000-3,000 miles. This is often related to the turbocharger, PCV system, or piston ring design. Subaru considers up to 1 quart per 1,200 miles as within normal range. Repairs typically run $0-$3,000. Severity: medium.
For 2024+ WRX models equipped with the Subaru Performance Transmission, owners have reported EyeSight and related driver-assistance features becoming unavailable, often accompanied by warning messages and disabled adaptive cruise or pre-collision functions. This is well documente… Repairs typically run $0-$1,800. Severity: medium.

Multiple VB-generation WRX owners have reported oil leaking from the turbocharger oil feed area, often traced to the banjo bolt or sealing washers on the turbo oil supply line. The leak typically shows up as a burning oil smell after driving, light smoke from the engine bay, or v… Repairs typically run $150-$700. Severity: medium.
Subaru provides a diagnosis-led cleaning procedure for deposit-related running concerns. This is not a fixed-mileage service or proof that deposits cause every misfire. Severity: medium.
Certain 2015–2016 WRX vehicles have a turbo air-intake duct made with unsuitable material. It may crack and cause rough idle, reduced power or stalling. VIN and supplier-lot checks determine the recall remedy. Severity: medium.
Owners on WRX and STI forums describe the power steering pump whining or groaning, often mainly when the engine is cold, sometimes with foamy fluid in the reservoir. Many trace it to the O-ring or O-rings at the fluid inlet on top of the pump, between the reservoir or suction fit… Severity: medium.
Turbo WRX engines have a secondary air system that pumps air into the exhaust for a short time after a cold start. Owners and a Subaru specialist shop report faults in this system that turn on the check-engine light. Some owners also describe a grinding, whining or screeching noi… Severity: medium.
Turbo WRX intake manifolds carry tumble generator valves — butterfly plates in each runner driven by a small electric actuator with a position sensor.
