The 2004 Subaru Impreza is a compact car offered as a 4-door sedan and 5-door wagon, known for standard all-wheel drive and confident year-round traction. It’s an ideal fit for drivers who want a practical daily commuter that can handle rain and snow, plus enthusiasts who appreciate Subaru’s rally-inspired handling. For 2004, the Impreza sits in the second-generation (2002–2007) lineup, positioned as a value-packed alternative to front-wheel-drive compact rivals. Depending on trim, it ranges from economical transportation to a more performance-leaning package.

1) STANDARD ALL-WHEEL DRIVE: Most 2004 Imprezas come with Subaru’s symmetrical all-wheel drive, a standout feature in the compact segment for stability in poor weather. 2) ENGINE OPTIONS: A 2.5-liter naturally aspirated flat-four (boxer) is common on many trims, delivering a strong low-to-midrange feel compared to typical small four-cylinders. Some trims also offered a 2.0-liter boxer (market/trim dependent). 3) TRANSMISSION CHOICES: Available with a 5-speed manual or 4-speed automatic, giving buyers flexibility between driver engagement and daily comfort. 4) PRACTICAL BODY STYLES: The wagon offers added cargo flexibility and is popular with outdoorsy owners who want compact dimensions with useful storage. 5) SAFETY AND ROAD MANNERS: Predictable handling, a low center of gravity from the boxer engine layout, and generally solid crash-safety fundamentals for its era contribute to its appeal.

Shoppers searching “2004 Subaru Impreza reliability” should know these cars can be long-lasting with proper upkeep, but there are recurring complaints to watch for. The most discussed “2004 Subaru Impreza problems” typically include: 1) HEAD GASKET SEEPAGE (2.5L ENGINES): External coolant or oil seepage around the head gaskets is a well-known concern on certain Subaru 2.5L engines. It may appear anywhere from roughly 80,000–150,000 miles, often showing up as coolant smell, minor drips, or repeated low coolant. Not every car is affected, but evidence of prior repair or a clean bill of health from inspection matters. 2) OIL CONSUMPTION AND MINOR LEAKS: Some owners report oil use between services or leaks from valve cover gaskets and cam seals as mileage climbs (often 100,000+ miles). Regular oil-level checks are important because boxer engines can be less forgiving if run low. 3) WHEEL BEARINGS AND SUSPENSION WEAR: Wheel bearing noise (a humming that changes with speed) is a commonly reported issue on older Imprezas, frequently appearing around 90,000–140,000 miles. Struts, sway bar links, and bushings can also wear, leading to clunks or uneven tire wear. 4) RUST IN SNOWBELT AREAS: In regions with heavy road salt, rust can develop on rear quarter panels, subframes, brake/fuel lines, and suspension mounting points. Rust isn’t universal, but it’s one of the most important “common issues” to inspect before buying.
