2015 Ford Focus: what breaks, and at what mileage

The failures owners actually file about

Owners have reported 63 named failure modes on the 2015 Ford Focus, and the three most-reported carry 42% of everything filed.

Other powertrain problem leads with 385 reports, about 2.1 per 1,000 vehicles and with the middle half of reports between 28k to 82,000 miles.

Other engine problem follows with 104 reports, usually reported between 37k to 105,000 miles. 2 of those reports mention a fire.

Other fuel system problem follows with 70 reports, usually reported between 53k to 87,500 miles. 1 of those report mention a fire.

By system, the reports fall mostly into transmission (479), fuel (163) and engine (162).

How bad it is when it goes

Across the named modes, 33 mention a crash, 4 a fire and 18 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 4.18, 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 engine problem at $300–$4,000, other fuel system problem at $300–$2,200 and fuel tank, filler or EVAP failure at $250–$1,800. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.

53% 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, so more than half of what owners complained about here is expensive.

How often, against how many were built

Scaled by an estimate of how many of these cars exist, the 2015 Ford Focus draws about 7.3 per 1,000 vehicles, which puts it in the 87th percentile of complaint rates among 2015 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 183,228 vehicles. If the true number is twice that, every rate on this page is half what it says; the ranking against other 2015 vehicles, which is what the risk score uses, is far more robust than the rate itself.

Recalls on the 2015 model year

NHTSA has issued 9 recall campaigns covering the 2015 Ford Focus, affecting an estimated 597,354 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 fuel system, gasoline:storage:evaporative emissions:canister, power train:manual transmission, equipment:electrical:engine block heater and latches/locks/linkages:doors:latch. 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.

Recalls also distort complaint counts. Publicity about a campaign reminds owners that complaining is possible, so reports for a recalled component often spike after the recall rather than before it.

How 2015 compares with the other years

Severe risk for a 2015 — 70th riskiest of the 273 2015 vehicles we can rate. Because the ranking is against the same model year only, age cancels out of it.

Across the 20 model years of this car that carry enough reports to score, 1999 comes out best at 55 and 2014 worst at 80, with 2015 itself at 75.

If the model year is negotiable, 1999, 2011, 2009, 2004, 2010, 2005, 2003, 2001 and 2000 score lower than 2015 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 2012–2018 generation specifically, 2018 is the strongest year at 74 and 2014 the weakest at 80.

What to look at before buying one

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: dual-clutch or clutch-pack failure from about 10k, other electrical problem from about 12k, seat belt or retractor failure from about 14k and other body or interior problem from about 15k.

On a 2015 Ford Focus with more miles than that on it, the useful question to put to a seller or a mechanic is whether dual-clutch or clutch-pack failure 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.

None of this is a diagnosis. It is a list of what other owners of the same model year reported, ordered by when they reported it, which is a good place to point an inspection and a poor place to stop.

What this page cannot tell you

1,329 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 1,329 reports, 841 carried an odometer reading, so the mileages here describe 63% 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".

Named failure modes come from matching phrases in the complaint text, so a badly worded complaint can land in the wrong bucket. The effect washes out across hundreds of reports and does not wash out across five.

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.
