Hey guys! Let's dive into the 2004 Subaru Impreza and Legacy, two awesome cars that have captured the hearts of many. But, like any vehicle, they have their quirks. We're going to explore the common issues and reliability aspects of these models so you know exactly what you're getting into! Whether you're a seasoned Subaru enthusiast or a newbie considering joining the family, this is for you.

Common Issues with the 2004 Subaru Impreza

The 2004 Subaru Impreza, known for its rally-inspired performance and all-wheel-drive capability, isn't without its potential headaches. One of the most talked-about issues involves the infamous head gaskets. Many owners have reported head gasket failures, which can lead to coolant leaks, overheating, and significant engine damage. Keep an eye on your temperature gauge and coolant levels, folks! If you notice anything suspicious, it's best to get it checked out ASAP. Another area to watch is the timing belt. Subaru recommends replacing the timing belt every 60,000 miles. If it breaks, it can cause catastrophic engine damage, especially in interference engines. So, if you're buying a used 2004 Impreza, make sure the timing belt service is up to date. Besides these major concerns, some owners have also reported issues with the oxygen sensors, which can affect fuel economy and emissions. A faulty O2 sensor can cause your Impreza to run poorly, so it's worth investigating if you notice a drop in MPG or a check engine light. Rust can also be a problem, especially in areas where salt is used on the roads during winter. Inspect the undercarriage and wheel wells for any signs of corrosion. Addressing rust early can prevent it from spreading and causing more serious damage down the line. Finally, keep an ear out for any unusual noises from the suspension. Worn-out struts, ball joints, and bushings can lead to a bumpy ride and affect handling. Regular maintenance and timely repairs can help keep your 2004 Impreza running smoothly for years to come. Remember, preventative care is always cheaper than major repairs!

Common Issues with the 2004 Subaru Legacy

Now, let’s switch gears and talk about the 2004 Subaru Legacy. This car is praised for its reliability and practicality, but it's not immune to problems either. Like the Impreza, the Legacy can also suffer from head gasket issues, particularly in the 2.5-liter engine. Keep an eye out for the same symptoms: coolant leaks, overheating, and white smoke from the exhaust. Regular coolant checks are crucial. The automatic transmission in the 2004 Legacy can sometimes experience issues. Some owners have reported slipping gears or harsh shifting. If you notice any problems with the transmission, it's essential to get it checked by a qualified mechanic to prevent further damage. Suspension components, such as struts and control arm bushings, can wear out over time, leading to a less comfortable ride and potentially affecting handling. Listen for any clunking or rattling noises from the suspension, especially when going over bumps. Rust is another potential concern, especially in areas with harsh winters. Inspect the undercarriage, wheel wells, and body panels for any signs of corrosion. Addressing rust early can prevent it from spreading and causing more significant damage. The 2004 Legacy is also known for its comfortable interior, but some owners have reported issues with the power windows and door locks. These electrical components can sometimes fail, requiring replacement. While the 2004 Legacy is generally a reliable car, addressing these potential issues promptly can help ensure it remains a dependable vehicle for years to come. Regular maintenance and inspections are key to keeping your Legacy in top condition.

Reliability of the 2004 Subaru Impreza

When we talk about the reliability of the 2004 Subaru Impreza, it's a mixed bag. On one hand, the Impreza is known for its robust all-wheel-drive system, which provides excellent traction in various weather conditions. This makes it a popular choice for those living in areas with snow or rain. However, the Impreza's reliability can be affected by several factors. As we mentioned earlier, head gasket failures are a common issue, which can be expensive to repair. The severity of this problem can vary depending on how well the car has been maintained. Regular maintenance, such as oil changes and coolant flushes, can help prevent head gasket issues, but they are not a guaranteed fix. Another factor that affects the Impreza's reliability is the driving style of the owner. The Impreza is often driven hard, especially the WRX and STI models, which can put extra strain on the engine and other components. If you're considering buying a used Impreza, it's essential to get it inspected by a qualified mechanic to assess its overall condition. Despite these potential issues, many owners have had positive experiences with their 2004 Imprezas. With proper maintenance and timely repairs, the Impreza can be a reliable and enjoyable car to own. However, it's crucial to be aware of the potential problems and factor them into your ownership costs.

Reliability of the 2004 Subaru Legacy

Let's shift our focus to the reliability of the 2004 Subaru Legacy. In general, the Legacy is considered to be a more reliable car than the Impreza. It's known for its comfortable ride, spacious interior, and practical features. However, like any car, the Legacy has its potential weaknesses. One of the most common issues is, again, the head gasket problem, especially in the 2.5-liter engine. While not every Legacy will experience this issue, it's something to be aware of. Regular coolant checks and maintenance can help prevent it, but it's not a foolproof solution. Another area to watch is the automatic transmission. Some owners have reported issues with slipping gears or harsh shifting. If you notice any problems with the transmission, it's essential to get it checked by a qualified mechanic to prevent further damage. Suspension components, such as struts and control arm bushings, can wear out over time, leading to a less comfortable ride and potentially affecting handling. Regular inspections and timely replacements can help keep the suspension in good condition. Rust is another potential concern, especially in areas with harsh winters. Inspect the undercarriage, wheel wells, and body panels for any signs of corrosion. Addressing rust early can prevent it from spreading and causing more significant damage. Despite these potential issues, the 2004 Legacy is generally a reliable car. With proper maintenance and care, it can provide years of dependable service. It's a good choice for those looking for a comfortable and practical sedan or wagon.

Maintenance Tips for Both Models

Whether you own a 2004 Subaru Impreza or a Legacy, proper maintenance is key to keeping your car running smoothly and reliably. Here are some essential maintenance tips for both models:

• Regular Oil Changes: Change your oil and filter every 3,000 to 5,000 miles, depending on your driving conditions. Use the recommended oil type and filter for your Subaru.
