2004 Subaru WRX
Common problems & what to know before you buy
Before you message the seller, know the documented failure patterns, repair cost exposure, and risk level for the 2004 Subaru WRX.
What to watch for on the 2004 Subaru WRX
5-Speed Transmission Failure (WRX)
The WRX's 5-speed manual is fragile — 2nd gear and the center differential often fail under hard driving or launches. The STI's 6-speed is much stronger. Consider an STI 6-speed swap for WRX owners.
Ringland Failure (EJ255/EJ257)
Piston ringlands can crack, causing low compression and knocking. Most common on modified or poorly tuned cars. A stock car with proper maintenance is less at risk. Listen for knocking at idle.

Subaru WRX (GD) Buyer's Guide
The Bugeye and Beyond
The GD WRX (2002-2007) put Subaru on the map in America. The original 2002 'bugeye' with its distinctive headlights, the 2004 blobeye, and 2006 hawkeye — each is a beloved chapter in Subaru's performance history. The GD is the most raw, unfiltered WRX.
Powertrain: The 2.0L EJ205 turbo (227 hp, 2002-2005) with 5-speed manual is the original — responsive, revvy, and iconic. The 2.5L EJ255 turbo (230 hp, 2006-2007) with 5-speed manual brought more torque. The STI (2004-2007) used a 2.5L EJ257 (300 hp) with 6-speed manual and DCCD AWD. The STI's 6-speed is stronger than the WRX's 5-speed.
What to look for: Never buy a modified GD WRX. These cars attract owners who modify them without proper tuning. A stock car with complete service records is worth a $3,000-5,000 premium. The 5-speed transmission in the WRX is glass — it breaks under hard launches. The STI's 6-speed is much stronger. Rust on rear wheel arches is common.
About the GD
The 2002-2007 Subaru WRX (GD chassis) introduced the brand’s turbocharged all-wheel-drive sedan to the US market, establishing the template for a generation of affordable performance cars. The WRX was offered solely as a four-door sedan, while the higher-performance WRX STI arrived in 2004 as a separate model. Early WRX sedans (2002-2005) used a 2.0-liter turbocharged flat-four, transitioning to a 2.5-liter turbo engine in 2006; the STI used a 2.5-liter turbo from its debut. Transmission choices included a five-speed manual for the WRX, a six-speed manual for the STI, and an optional automatic for the WRX. All models featured Subaru’s symmetrical all-wheel drive.
This generation marked a significant leap from the previous Impreza-based non-turbo models, offering a rally-bred driving experience that was direct and communicative. The 2002-2007 Subaru WRX is prized by enthusiasts for its stiff chassis, precise steering, and turbocharged responsiveness. As a used buy, it suits drivers who value analog driving dynamics and are willing to accept a firm ride and modest interior refinement. The generation’s reputation is strong overall, though potential buyers should verify maintenance history, especially for the later 2.5-liter engines. These cars remain a benchmark for compact all-wheel-drive performance sedans.

Frequently asked questions
Should I buy a modified GD WRX?
Generally no — questionable tuning is the #1 cause of EJ engine failure. A stock car with service records is worth a big premium. If you must buy modified, get a compression and leak-down test.
WRX vs STI of this era?
The STI has a stronger 6-speed, bigger brakes, DCCD AWD, and holds value better. The WRX is lighter and more tossable. The STI is the investment-grade choice; the WRX is the budget-friendly driver's car.
