1999 Subaru Legacy: what breaks, and at what mileage

What breaks on the 1999 Subaru Legacy

On the 1999 Subaru Legacy, the failure owners report most often is other powertrain problem, with 11 reports on file. Across every failure mode on this year, half the dated reports were filed before 100,000 miles. Overall it scores 62 out of 100, high risk for a 1999.

High risk for a 1999 — 237th riskiest of the 303 1999 vehicles we can rate. 119 owner reports; fleet size estimated from this year's own recall paperwork.

The failures owners actually file about

Owners have reported 37 named failure modes on the 1999 Subaru Legacy, and the three most-reported carry 23% of everything filed, which is an unusually even spread for one model year.

Other powertrain problem leads with 11 reports and about 0.2 per 1,000 vehicles.

Other speed control problem follows with 9 reports, median 70,000 miles.

ABS module or sensor failure follows with 7 reports.

By system, the reports fall mostly into brakes (20), transmission (16) and adas (10).

When these failures get reported

34 of the reports on the 1999 Subaru Legacy came with an odometer reading, and half of those were filed before 100,000 miles.

Cumulatively, 12% by 50,000 miles, 47% by 100,000 miles and 82% by 150,000 miles of the dated reports had been filed.

The busiest stretch is between 60,000 and 70,000 miles, which alone holds 15% of the dated reports.

3% of the dated reports were filed below 36,000 miles, so this is mostly a story about older, higher-mileage cars.

What happens when these parts fail

Across the named modes, 23 mention a crash, 1 a fire and 10 an injury. Those are the words owners used in their own complaints, and NHTSA does not verify them, but they are the closest thing in this data to a measure of what a failure actually did.

The average severity weight across every report on this year is 6.03, where a stalled engine or a failed airbag weighs many times more than a rattling trim panel, and a figure this high means the reports are dominated by failures with safety consequences rather than annoyances. The weighting is set out in full on the methodology page.

What the top failures cost to put right, as editorial estimates for an independent US shop rather than figures from NHTSA: other powertrain problem at $400–$4,500, other speed control problem at $250–$2,000, ABS module or sensor failure at $500–$2,400 and other body or interior problem at $200–$2,000. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

26% of the reports on this year sit in the engine, transmission, drivetrain or cooling systems — the four where a repair bill is usually four figures.

Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound. Repair costs are typical independent-shop ranges for the failure, not figures from these reports.

How often, against how many were built

Scaled by an estimate of how many of these cars exist, the 1999 Subaru Legacy draws about 2.1 per 1,000 vehicles, which puts it in the 74th percentile of complaint rates among 1999 vehicles we can rate.

That denominator is the weakest number on the page and it is fair to say so plainly. Rate per 1,000 uses a fleet-size estimate derived from recall paperwork for this exact model year. It is a lower bound.

The working figure is 55,496 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 1999 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Recalls on the 1999 model year

NHTSA has issued 3 recall campaigns covering the 1999 Subaru Legacy, affecting an estimated 88,149 vehicles. A recall is a different kind of evidence from a complaint: it is the regulator and the manufacturer agreeing that something has to be fixed, and the fix is free for as long as the car exists.

The campaigns cover suspension:front:springs:coil springs, service brakes, hydraulic:foundation components:master cylin and engine and engine cooling:engine. Whether the work was actually done on the car in front of you is a question only the VIN can answer, and the manufacturer or NHTSA will answer it free.

One caution about reading these together: a recall usually raises the complaint count for the same part, because owners who read about it go and file. The mileages stay informative; the counts get noisy.

01V216000

SUSPENSION:FRONT:SPRINGS:COIL SPRINGS

180,000 vehicles 2001-06-25

Defect: Vehicle description: passenger vehicles equipped with front coil springs originally sold in or currently registered in the states of connecticut, delaware, illinois, indiana, iowa, kentucky, maine, maryland, massachusetts, michigan, minnesota, missouri, new york, new jersey, new hampshire, ohio, pennsylvania, rhode island, vermont, virginia, west virginia, and wisconsin, and in the district of columbia. The front coil springs were produced with poor paint quality which, after continued exposure to corrosive salt, can result in breakage of the spring.
Consequence: Depending on the location of the fracture, a broken spring could move past the spring seat and contact a front tire. Some tires have deflated due to contact with a broken spring.
Remedy: Dealers will notifiy customers to bring their vehicle to an authorize dealership to have a spring guard installed on both front struts to prevent tire puncture and replace any broken springs free of charge. Owner notification began september 18, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact subaru at 1-800-782-2783.

99V040000

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:MASTER CYLINDER

221,987 vehicles 1999-03-03

Defect: Vehicle description: passenger and sport utility vehicles equipped with anti-lock braking system (ABS). (the 1999 2.2 liter legacy vehicles are excluded). In extremely cold weather, the brake pedal goes to the floor and the vehicle stopping distance is increased.
Consequence: This condition causes the vehicle stopping distance to be increased, possibly resulting in a crash.
Remedy: Dealers will replace the brake master cylinder.

98V127000

ENGINE AND ENGINE COOLING:ENGINE

20,306 vehicles 1998-06-08

Defect: Vehicle description: passenger vehicles, also service parts supplied to subaru dealers are involved (lot numbers f01 j21d2, f01 j30d2, f02 j09d1, f02 j09d2, and f02 j20d1). The purolator oil filter cans used on these vehicles can fracture causing a vaporized oil spray and subsequent oil leak.
Consequence: This vaporized oil spray can result in oil vapor ignition by the hot exhaust system resulting in a possible underhood fire.
Remedy: Dealers will inspect and replace these engine oil filters.

Recall work is free at a franchised dealer regardless of the car's age. Check the VIN at nhtsa.gov/recalls before assuming it was done.

How it ranks in the 1999 field

The score at the top of the page, placed among its peers. The zones are the same thresholds the scorer applies, read out of the scorer itself, so the picture and the band word cannot disagree.

Risk score against the rest of the 1999 field

Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.

How 1999 compares with the other years

High risk for a 1999 — 237th riskiest of the 303 1999 vehicles we can rate. Every score on this site is a rank inside its own model year, which is what makes a 2004 and a 2019 comparable at all.

Across the 28 model years of this car that carry enough reports to score, 1996 comes out best at 60 and 2015 worst at 78, with 1999 itself at 62.

No other year of this model scores meaningfully better than 1999, so if this generation is what you want, the year is not the lever.

Within the 1996–1999 generation specifically, 1996 is the strongest year at 60 and 1998 the weakest at 65.

Scores compare each year against other cars of the same model year, so a low number on an older car is a real result and not an artefact of age.

Risk score by model year, out of 100

Shorter is better. Years with too few reports to score are shown without a bar rather than as a zero, because no data is not good news.

Within the 1996-1999 generation, 1996 Subaru Legacy scores best at 60 and 1998 Subaru Legacy worst at 65.

What this page cannot tell you

119 owner reports; fleet size estimated from this year's own recall paperwork. Every count on this page is therefore a floor: it is the number of owners who went to the trouble of filing with a federal agency, which is a small and self-selected fraction of the owners who had the fault.

Of those 119 reports, 34 carried an odometer reading, so the mileages here describe 29% of the sample rather than all of it. Owners also round: readings pile up on multiples of ten thousand, which is why this site publishes "about 90,000 miles" and not "91,438".

The failure modes are assigned by software reading the owner's own words, which is accurate in bulk and wrong in individual cases. A mode with a handful of reports may contain a misfiled one.

And nothing here predicts what one car will do. These are other people's complaints, filed years apart, on cars maintained by strangers. Read the page as a map of where this model year has previously gone wrong, then have the specific car in front of you inspected.

Questions this page answers

What are the most common problems with the 1999 Subaru Legacy?

The most-reported failures are other powertrain problem (11 reports, median 85,000 miles), other speed control problem (9 reports, median 70,000 miles) and abs module or sensor failure (7 reports). Counts come from owner complaints filed with NHTSA, which are voluntary, so they show what owners bothered to report rather than every fault that occurred.

Is the 1999 Subaru Legacy reliable?

It scores 62 out of 100 on our risk index, which is high — 237th riskiest of the 303 1999 vehicles we can rate. The score is a comparison against other 1999 vehicles, not a prediction about any individual car, and it is built from complaint rates, severity and how early failures appear.

Which year of the Subaru Legacy is best?

Within the 1996–1999 generation, 1996 scores best at 60 out of 100 and 1998 worst at 65. Same body, same engines, different luck.

Where this comes from. Every figure above is computed from NHTSA owner complaints and recall records for this exact make, model and year. Complaints are voluntary and self-selected, so treat counts as a floor. The methodology page writes out each formula, and the same numbers are available as JSON.
