Is a 2007 Subaru reliable?
A well-maintained 2007 Subaru can still be reliable, but reliability varies by model, maintenance history, and mileage. The most important factors are documented service records and a thorough pre-purchase inspection to spot common issues such as head gasket concerns on the 2.5-liter engine and potential oil consumption.
Understanding reliability for 2007 Subarus
In 2007, Subaru offered several configurations, including the Outback and Legacy wagons and sedans with a 2.5L four-cylinder engine and, in some trims, a 3.0L six-cylinder. All-wheel drive is common in many models, boosting versatility and longevity when properly cared for, but it also adds maintenance considerations. Reliability hinges on model choice, engine type, and how diligently the vehicle has been serviced over time.
Engine options and reliability considerations
The popular 2.5L EJ25 four-cylinder powers many 2007 Subarus and is known for solid efficiency, but it carries a higher risk of head gasket leaks and oil consumption in high-mileage examples. The 3.0L H6 offers smoother operation and can be reliable, but it requires attention to cooling system health and timing components. Both engines benefit from regular cooling-system maintenance and timely belt/timing service to prevent failures.
Below are the reliability concerns you should be aware of when evaluating a 2007 Subaru.
- Head gasket leaks and coolant/oil contamination on the 2.5L EJ25 engines; watch for overheating, milky oil, coolant loss, or white exhaust smoke.
- Oil consumption, particularly in higher-mileage 2.5L units; monitor oil level and look for blue smoke or oil burning indications.
- Timing belt (and water pump) service needs; the belt drives the water pump and should be replaced at the recommended interval to avoid catastrophic engine damage.
- Suspension wear and wheel bearings/CV joints; older struts, bushings, and CV axles can cause rough ride and noise.
- Automatic transmission wear or CVT concerns depending on model; ensure fluid service and check for slipping or shuddering if equipped with a 4EAT or CVT.
- Rust and underbody corrosion in harsh climates; check frame rails and floor pans, especially on cars from salt-prone areas.
Handling these items through a thorough pre-purchase inspection and documented maintenance history can improve long-term reliability for a 2007 Subaru.
Maintenance habits that boost reliability
To maximize reliability in a 2007 Subaru, adhere to model-specific maintenance schedules and address issues proactively. The following actions are particularly important.
- Follow the factory timing belt/chain and water pump schedule for the engine you own; replace belts, water pump, and related tensioners together to avoid future breakdowns.
- Keep up with regular oil changes using the recommended viscosity and quality; monitor oil consumption and address leaks promptly.
- Address engine cooling system problems early; replace hoses, radiator, thermostat, and coolant as needed to prevent overheating that can stress gaskets.
- For automatics, service the transmission fluid and filter as recommended; early signs of slipping should prompt a closer inspection or internal service.
- Inspect and replace aging suspension components and wheel bearings; maintain proper alignment to reduce tire wear and improve handling.
- Check the AWD system components, center differential fluid, and CV joints regularly; replace worn components to avoid drivetrain noise and uneven wear.
With diligent upkeep, a 2007 Subaru can remain dependable for daily driving and light adventure use.
Model-specific reliability notes
Outback and Legacy wagons
These models often share the 2.5L engine and 3.0L H6 options. While they offer spacious cargo and all-weather capability, their reliability hinges on cooling-system health, head gasket integrity, and timely belt/timing service as they accumulate miles.
Impreza (sedan/hatch)
Impreza models with the 2.5L engine present similar reliability patterns to the Outback/Legacy in terms of head gasket risk and oil consumption, with AWD performance contributing to drivetrain durability when properly maintained.
What to check before buying a 2007 Subaru
Before purchasing a 2007 Subaru, obtain a full history and perform a thorough in-person inspection. The following checks help determine how reliable the car may be moving forward.
- Verify recall status for the VIN and ensure related service work has been completed; check with the NHTSA database and Subaru's recall portal.
- Request service records for timing belt and water pump replacement, head gasket work, and cooling-system maintenance.
- Conduct a compression test and leak-down test to assess engine health, especially if the engine is the 2.5L EJ25.
- Inspect for signs of head gasket failure: coolant leaks, white exhaust, milky oil, overheating history.
- Check transmission behavior: smooth shifts, no slipping or rough shifts; verify fluid condition and level.
- Inspect undercarriage for rust and inspect for oil or coolant leaks, as well as worn suspension components.
Buyers should weigh the vehicle's overall maintenance history and condition against the asking price, and consider a professional inspection prior to finalizing a deal.
Summary
In summary, a 2007 Subaru can be a reliable used car if it has a solid maintenance record and has addressed known issues like head gasket risk on the 2.5L engine and oil consumption. The model you choose, mileage, and how well previous owners cared for it are decisive factors. A thorough pre-purchase inspection, awareness of recalls, and commitment to timely maintenance markedly improve long-term reliability.
