Source: NHTSA Office of Defects Investigation, public domain. Complaint counts reflect what owners reported and are not a measure of failure rate per vehicle sold.

What this can and cannot tell you: these are complaints owners chose to file, not a failure rate. Popular models accumulate more of them simply by being common. How this is built.

Owners filed 890 complaints with NHTSA about the 2003–2008 Subaru Forester, and 716 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.

Failures are spread across the mileage range, with the middle half between 45,653 and 126,000 miles. The median is 81,550 miles.

The most-reported areas are the fuel and propulsion system (13.1% of complaints, typically around 120,000 miles), the fuel system (13.0% of complaints, typically around 85,000 miles), the suspension (11.5% of complaints, typically around 126,000 miles).

1 recall campaign cover this generation.

If you arrived asking “is it reliable?” — this page answers the version of that question the data can support: which problems owners reported, and at what mileage.

How many miles does a 2003–2008 Subaru Forester last?

Half of the failure reports on the 2003–2008 Subaru Forester were filed by 82,000 miles and 90% by 159,000 miles — figures drawn from 716 NHTSA complaints that record an odometer reading, so they time reported failures, not the cars whose owners never filed one.

17 reports (2.4%) came in past 200,000 miles — each one proof a Forester reached that mileage, not that it died there.

Before you buy a 2003–2008 Forester: the 3-minute check

Generated from 716 mileage-tagged complaints, 1 recall campaign, 4 documented problem areas. Print this page — the checklist survives print.

  1. Run the VIN at nhtsa.gov/recalls. 1 campaign cover this generation; an open recall is a free repair you can make the seller's problem.
  2. Check head gaskets (ej253 sohc) on 2003–2008 cars. External head gasket coolant seepage on the naturally aspirated SOHC engine, same mechanism as the late first generation - slow coolant loss, weeping at the head-to-block joint.
  3. Check turbocharger (ej255, xt only) on 2004–2008 XT cars. Turbocharger failure from oil starvation, commonly traced to the banjo bolt filter screen in the turbo oil feed line clogging with sludge or debris. Subaru later deleted the screen. Failing turbos frequently send debris…
  4. Check engine (ej255 pistons) on 2004–2008 XT cars. Ringland failure on the turbocharged EJ255 - the piston ring land fractures under detonation, producing loss of compression and blow-by. Heavily concentrated on tuned or hard-driven cars.
  5. Complaint reports are not spread evenly across model years here — see the by-model-year table below before you settle on a year.
  6. End with a pre-purchase inspection of this car. Aggregate data describes the population; the example in front of you has its own history.

For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 46,000 and 126,000 miles, with a median of 82,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, the fuel and propulsion system and the fuel system are where this generation's reports concentrate, so those are the areas worth a specific look. The fuel system in particular shows a median failure mileage of 85,000, which gives a concrete number to compare against the odometer of any car you are considering.

None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

Which systems, and when

Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 81,550 miles; the figures below show which parts of the car run ahead of that and which run behind.

The fuel and propulsion system accounts for 13.1% of complaints (117 reports, 99 of them with a mileage figure), and it fails late — a median of 120,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 83,000 and 150,000 miles.

The fuel system accounts for 13.0% of complaints (116 reports, 109 of them with a mileage figure), with a median of 85,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 55,000 and 114,000 miles.

The suspension accounts for 11.5% of complaints (102 reports, 81 of them with a mileage figure), and it fails late — a median of 126,000 miles, considerably beyond the vehicle's overall median. That pattern is consistent with normal service life rather than a defect, though it matters for anyone buying an example already near that mileage. The middle half of these reports falls between 89,000 and 158,000 miles.

Throttle and speed control accounts for 8.7% of complaints (77 reports, 64 of them with a mileage figure), and it fails early — a median of 51,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 16,000 and 82,000 miles.

The airbag system accounts for 8.1% of complaints (72 reports, 53 of them with a mileage figure), with a median of 59,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 34,000 and 90,000 miles.

The engine accounts for 7.3% of complaints (65 reports, 57 of them with a mileage figure), with a median of 108,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 76,000 and 133,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2004 model year drew the most — 270 complaints — while 2008 drew the fewest at 67. The median year sits at 113.

That makes 2004 an outlier: roughly 2.4 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.

Recalls and what they cover

NHTSA records 1 recall campaign covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.

Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

Reported severity

What owners reported alongside the failure itself, out of 890 complaints against this generation:

These flags are self-reported by complainants and unverified by NHTSA; one report can carry several flags, so the counts overlap and do not sum to a total. They are not adjusted for how many of these vehicles are on the road. No chart is drawn here on purpose: overlapping counts spanning very different magnitudes cannot be honestly encoded as lengths.

Documented problems

Head Gaskets (ej253 Sohc) 2003–2008

External head gasket coolant seepage on the naturally aspirated SOHC engine, same mechanism as the late first generation - slow coolant loss, weeping at the head-to-block joint.

Turbocharger (ej255, Xt Only) 2004–2008 XT

Turbocharger failure from oil starvation, commonly traced to the banjo bolt filter screen in the turbo oil feed line clogging with sludge or debris. Subaru later deleted the screen. Failing turbos frequently send debris into the engine, escalating cost.

Engine (ej255 Pistons) 2004–2008 XT

Ringland failure on the turbocharged EJ255 - the piston ring land fractures under detonation, producing loss of compression and blow-by. Heavily concentrated on tuned or hard-driven cars.

Wheel Bearings 2003–2008

Continued front and rear wheel bearing failure across the generation.
