What is the 1993-1999 Subaru Impreza Rear Wheel Arch, Rocker Panel, and Subframe Rust?
1993-1999 Imprezas (GC8/GF8/GM sedan, coupe, and wagon) are highly prone to corrosion at the rear wheel arches, rocker panels, and the rear subframe/crossmember, particularly in salted-road climates. The outer quarter panel and wheel housing are joined with spot welds and foam ad… Repairs typically run $300-$2,500. Severity: high.
What is the 1997-1999 Subaru Impreza Interference-Engine Timing Belt Neglect (DOHC EJ25 / 1997+ SOHC)?
The 2.5L DOHC EJ25D and the 1997-and-later SOHC EJ engines are interference designs: if the rubber timing belt breaks or a belt idler/tensioner pulley seizes, the pistons strike open valves and bend them, destroying the top end. From 1997 all USDM Subaru EJ engines (including the… Repairs typically run $500-$1,000. Severity: high.
What is the 1998-1999 Subaru Impreza Phase I EJ25D DOHC 2.5L Internal Head Gasket Failure?
The first-generation 2.5L DOHC boxer (EJ25D) used in the 1998-1999 Impreza 2.5 RS (and shared with the 1996-1999 Legacy/Outback/Forester of the era) is notorious for internal head gasket failure. In 1996 Subaru used a composite gasket, then from 1997 switched to a multi-layer-ste… Repairs typically run $1,200-$2,600. Severity: high.
What is the 1993-1999 Subaru Impreza Automatic (4EAT) AWD Torque Bind / Duty C Solenoid Failure?
Automatic-transmission 1990s Imprezas use the 4EAT with an electronically managed transfer clutch (governed by the Duty C solenoid) to split torque to the rear wheels.

What is the 1993-1999 Subaru Impreza Front (and Rear) Wheel Bearing / Hub Failure?
Pressed-in front wheel bearings on the 1993-2001 Impreza chassis are a recurring wear item; the bearings were sized for the small factory 15-16 inch wheels, and larger aftermarket wheels, high mileage, or hard cornering accelerate failure. A failed bearing hums or roars proportio… Repairs typically run $200-$600. Severity: medium.
What is the 1993-1999 Subaru Impreza Distributor Cap, Rotor, and Ignition Moisture Misfire (SOHC EJ18/EJ22)?
The SOHC EJ18 and EJ22 engines in the base 1990s Impreza use a camshaft-driven distributor. With age, the cap and rotor corrode and crack, and the distributor O-ring can weep oil into the cap. This causes crossfire and weak spark that shows up as rough idle, hesitation, and hard… Repairs typically run $60-$250. Severity: low.
