Subaru Forester 2003-2008: problems, fuel economy, powertrain, AWD system
No other SUV can compete with the Forester when it comes to a comfortable ride, fuel economy and excellent visibility. The Suby offers a 4-cylinder horizontally-opposed 'boxer' engine and standard all-wheel drive.

The Subaru all-wheel drive system is one of the best. The 2003-2008 Forester received 5-star ratings in the NHTSA crash tests.
The interior is simple and functional. Front seats are supportive and comfortable on long trips. The optional sunroof is huge. Available front and rear wiper deicers along with heated seats and mirrors are a big plus for winter conditions. Is the Forester reliable? What are the reported problems?
Subaru Forester problems: Oil leaks from seals and gaskets are common. If a large amount of oil leaks out, the engine can get damaged from running low on oil. This means, check the oil level regularly and top up as needed. Repair options depend on the source of the leak. Some seals and gaskets are often replaced when changing the timing belt.
There have been reports of head gaskets leaking at higher mileage. Symptoms include overheating, losing coolant, as well as a smell of coolant coming from under the hood. Replacing head gaskets is costly ($1,000-$1,600).
Failed catalytic converters have also been reported; some owners mentioned that they opted for cheaper aftermarket parts from a local muffler shop. Loose exhaust heat shields can cause a rattling noise at certain rpms. The heat shields must be re-secured; it's an easy repair.
Bad wheel bearings, CV-joints and struts are not uncommon. Replacing one wheel bearing cost from $190 to $350. Subaru issued a few recalls; check at the NHTSA website.
Powertrain: The Forester offers two engines of the EJ25 family: the 173-hp 4-cylinder 2.5L SOHC and the turbo-charged 224-hp 2.5L DOHC. Both are flat Boxer engines with cylinders arranged horizontally; two cylinders on each side. Read also: Pros and cons of buying a car with a turbocharger. Both engines have a timing belt that must be replaced at recommended intervals. The turbo-charged DOHC engine requires premium gasoline. Transmission choices include a 5-speed manual with a Hill Holder clutch or a 4-speed automatic.
Fuel Economy: The 2008 AWD Forester with a non-turbo engine and automatic transmission is rated at 20/26 mpg (11.8/9.0 L/100 km) by the U.S. EPA. This means that on one full 16.9-gallon (64 liter) tank, the Forester can travel for 335 miles (538 km).
Handling and ride: On the road, the Forester is fun to drive. The flat horizontally placed engine gives the Forester a low center of gravity and as a result, the tall Forester feels very stable on winding roads. At the same time, the ground clearance is high enough not to worry about hitting curbs. Overall, handling is secure with minimal body roll, even in tight corners. The steering is on the light side, but precise, with tight a turning radius.

The ride is fairly smooth. There is some wind and road noise at higher speeds, but not too intrusive. The non-turbo 2.5L engine has enough power for everyday driving. A turbo-charged engine is quicker, but is more expensive to maintain.
AWD System: What makes Subaru special is its Symmetrical All-Wheel Drive where the left and right axles are of the same length. Models with a manual transmission have an AWD system with a central limited slip differential. In automatic models the torque distribution is controlled electronically by a hydraulic transfer clutch.
A viscous limited-slip rear differential is available. Although the Forester's AWD system is not designed for rock climbing, it works well on slippery roads or in moderate off-road conditions. We drove the Forester through foot-deep snow and the vehicle handled with confidence.
Safety: Anti-lock Brakes (ABS) are standard. The 2003-2008 Subaru Forester received perfect five-star ratings in the NHTSA frontal and side-impact crash tests and four stars in dynamic rollover tests. The Forester also earned the 2008 Top Safety Pick award from IIHS.
Pros: Good fuel economy for an SUV, safety ratings, capable AWD system, low center of gravity, car-like handling, compliant ride, tight turning radius, visibility, decent ground clearance, standard roof rail.
Cons: Engine problems, plain interior, road and wind noise, tight rear seat space, no telescopic adjustment on the steering column, small cup holders.
Overall: Reliability was OK for a while, but with age, failed catalytic converters, blown head gaskets and other problems started to show up. At higher mileage the engine noises, misfiring and various leaks are often reported.
On the plus side, the Forester has scored well in the crash tests. It offers great all-around visibility and decent towing capacity for a small SUV. The AWD system is good too. Features like built-in roof rails and wiper deicers can be helpful.

What to look for when buying a used Subaru Forester: If the engine has been overheated in the past, avoid the car; overheating can cause many problems down the road. Watch out for oil and coolant leaks; the repair might be quite expensive. A burnt oil or coolant smell coming under the hood is an indication of leaks.
For models with a manual transmission, test the clutch. Watch out for a piston slap and other engine noises (tapping or knocking) when the car is started cold. Check if the timing belt has been replaced. If you notice blue smoke from exhaust, or from under the hood, especially when the engine is started, avoid the car.

Maintenance tips: Have your oil changed regularly, for the engine to last. A turbocharged engine is more sensitive to the oil quality; use only good quality oil. Check your tire pressure regularly; unequal tire pressure will cause increased wear of the 4WD system components. Overheating the engine may cause expensive damage; check the coolant (antifreeze) level and top up if it's low. Subaru recommends using a special cooling system conditioner whenever the coolant is changed, check with your Subaru dealer.
