2014 Mazda CX-9: what breaks, and at what mileage
What breaks on the 2014 Mazda CX-9
On the 2014 Mazda CX-9, the failure owners report most often is water pump failure, with 14 reports on file. Across every failure mode on this year, half the dated reports were filed before 52,500 miles. Overall it scores 70 out of 100, high risk for a 2014.
High risk for a 2014 — 155th riskiest of the 270 2014 vehicles we can rate. 73 owner reports; fleet size estimated from this year's own recall paperwork.
What breaks on the 2014 Mazda CX-9
Owners have reported 28 named failure modes on the 2014 Mazda CX-9, and the three most-reported carry 37% of everything filed.

What happens when these parts fail
Across the named modes, 1 mentions a crash and 1 a fire. 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 4.44, 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: water pump failure at $500–$2,200, complete engine failure or seizure at $4,500–$12,000, master cylinder or brake booster failure at $450–$2,200 and wheel bearing or hub failure at $350–$1,200. Dealer labour, a seized bolt or a part that is no longer made can push any of these past the top of its range.
49% 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 2014 Mazda CX-9 draws about 3.0 per 1,000 vehicles, which puts it in the 81st 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 24,185 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 Mazda CX-9, affecting an estimated 36,205 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 air bags:frontal:passenger side:inflator module, steering and suspension:front:control arm:lower arm. 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 it ranks in the 2014 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.
Scores are ranked within the model year, never across years, because an older car has had longer to accumulate reports.
- Left fewer and less serious reports
- Right more, or worse
- Marker this vehicle
Better and worse years of the same car
High risk for a 2014 — 155th riskiest of the 270 2014 vehicles we can rate. Because the ranking is against the same model year only, age cancels out of it.
Across the 16 model years of this car that carry enough reports to score, 2007 comes out best at 64 and 2018 worst at 82, with 2014 itself at 70.
If the model year is negotiable, 2007 and 2023 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 2007–2015 generation specifically, 2007 is the strongest year at 64 and 2010 the weakest at 74.
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.
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 2007-2015 generation, 2007 Mazda CX-9 scores best at 64 and 2010 Mazda CX-9 worst at 74.
What this page cannot tell you
73 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 73 reports, 38 carried an odometer reading, so the mileages here describe 52% 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.
Questions this page answers
What are the most common problems with the 2014 Mazda CX-9?
The most-reported failures are water pump failure (14 reports, median 100,000 miles), complete engine failure or seizure (7 reports, median 95,000 miles) and master cylinder or brake booster failure (6 reports, median 70,000 miles). 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 2014 Mazda CX-9 reliable?
It scores 70 out of 100 on our risk index, which is high — 155th riskiest of the 270 2014 vehicles we can rate. The score is a comparison against other 2014 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 Mazda CX-9 is best?
Within the 2007–2015 generation, 2007 scores best at 64 out of 100 and 2010 worst at 74. 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.
