2014 Subaru Impreza: what breaks, and at what mileage

What breaks on the 2014 Subaru Impreza

Owners have reported 36 named failure modes on the 2014 Subaru Impreza, and the three most-reported carry 24% of everything filed, which is an unusually even spread for one model year.

Airbag warning light or occupant sensor fault leads with 15 reports, about 0.3 per 1,000 vehicles and with the middle half of reports between 28k to 80,000 miles.

Other body or interior problem follows with 12 reports, usually reported between 33k to 85,000 miles.

Other engine problem follows with 11 reports, usually reported between 24k to 50,000 miles.

By system, the reports fall mostly into airbag (26), engine (20) and body (16).

Severity, and what it costs

Across the named modes, 20 mention a crash and 5 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 4.39, 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: airbag warning light or occupant sensor fault at $300–$1,600, other body or interior problem at $200–$2,000, other engine problem at $300–$4,000 and other electrical problem at $250–$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.

22% 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.

How often, against how many were built

Scaled by an estimate of how many of these cars exist, the 2014 Subaru Impreza draws about 2.9 per 1,000 vehicles, which puts it in the 80th percentile of complaint rates among 2014 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 54,313 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2014 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Recalls on the 2014 model year

NHTSA has issued 3 recall campaigns covering the 2014 Subaru Impreza, affecting an estimated 87,464 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 exterior lighting:brake lights:switch, engine and engine cooling:engine and electrical system. 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.

Better and worse years of the same car

High risk for a 2014 — 161st riskiest of the 270 2014 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 27 model years of this car that carry enough reports to score, 2015 comes out best at 65 and 2021 worst at 84, with 2014 itself at 70.

If the model year is negotiable, 2015 and 2003 score lower than 2014 by a margin worth acting on. Same body, same engines, different luck — usually a supplier change or a mid-cycle fix, which the complaint data can show but never explain.

Within the 2012–2019 generation specifically, 2015 is the strongest year at 65 and 2012 the weakest at 73.

Where to spend the inspection money

The mileages below are where the first quarter of reports for each mode had already been filed, which makes them the point at which a fault is worth looking for rather than the point at which it happens: other engine problem from about 24k, airbag warning light or occupant sensor fault from about 28k and other body or interior problem from about 33k.

On a 2014 Subaru Impreza with more miles than that on it, the useful question to put to a seller or a mechanic is whether other engine problem has been dealt with, and if so with what parts and at whose expense. A car that has already had the repair is in a different position from one that has not.

Treat it as where to point the inspection, not as a prediction. A well-maintained example can sail past every mileage on this page, and a neglected one can fail well before the first of them.

The limits of complaint data

158 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 158 reports, 95 carried an odometer reading, so the mileages here describe 60% 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.
