Common problems with the 2014 CX-9
NHTSA's file holds 54 owner complaints on the 2014 Mazda CX-9. Owners named the engine most often: 19 complaints, and half of the 8 that list a mileage came after 80,000 miles. A complaint can name more than one component.
| Component (NHTSA category) | Complaints | Listing mileage | Median mileage |
|---|---|---|---|
| Engine | 19 | 8 | 81,000 |
| Service Brakes | 9 | 5 | 48,000 |
| Power Train | 7 | 4 | Under 5 mileages |
| Fuel/propulsion System | 5 | 0 | Under 5 mileages |
| Suspension | 5 | 4 | Under 5 mileages |
Of the 54 complaints, 1 reports a crash, 1 reports a fire and none reports an injury. These are owners' reports to NHTSA, not findings.
Mileage when owners reported a problem with the 2014 CX-9
The 28 mileages owners gave run from 450 to 118,000 miles. A quarter are at or under 15,000 miles, half at or under 52,789, three quarters at or under 80,000 and nine in ten at or under 108,000; 4 (14%) came after 100,000 miles, none after 150,000 and none after 200,000.
These mileages say when owners reported a problem, not when a 2014 CX-9 wears out. NHTSA's file holds only vehicles whose owners complained; one that ran without a problem never appears in it, so it gives no lifespan and no cutoff, and how a vehicle was maintained matters more than any one odometer reading.
Most of these reports came early in the vehicle's life: 24 of the 28 came at or under 100,000 miles, so they say nothing about how many miles a 2014 CX-9 can cover.

Is the 2014 CX-9 a good year?
Complaint counts cannot say whether the 2014 is a good or a bad CX-9: they rise with how many were sold and how long they have been on the road. They show how the 2014 compares with the other model years in NHTSA's file.
With 54 complaints, the 2014 ranks 11th of the 17 Mazda CX-9 model years from 2007 to 2023 with 10 or more complaints, counting from the most, tied with 2019. The most: the 2012 (221). The fewest: the 2022 (11).
Recent model years have had less time to collect complaints, so their counts are still growing. No year is ranked by mileage here, because a year's median mileage mostly follows its age.
| Model year | Owner complaints | Listing mileage | Median mileage |
|---|---|---|---|
| 2007 CX-9 | 86 | 62 | 94,000 |
| 2008 CX-9 | 172 | 126 | 98,000 |
| 2009 CX-9 | 59 | 39 | 85,000 |
| 2010 CX-9 | 195 | 146 | 77,200 |
| 2011 CX-9 | 171 | 138 | 74,000 |
| 2012 CX-9 | 221 | 170 | 58,000 |
| 2013 CX-9 | 68 | 44 | 53,000 |
| 2014 (this page) | 54 | 28 | 52,789 |
| 2015 CX-9 | 35 | 20 | 56,000 |
| 2016 CX-9 | 108 | 29 | 40,000 |
| 2017 CX-9 | 61 | 5 | Under 10 mileages |
| 2018 CX-9 | 128 | 16 | 26,000 |
| 2019 CX-9 | 54 | 14 | 25,000 |
| 2020 CX-9 | 19 | 3 | Under 10 mileages |
| 2021 CX-9 | 41 | 5 | Under 10 mileages |
| 2022 CX-9 | 11 | 1 | Under 10 mileages |
| 2023 CX-9 | 13 | 1 | Under 10 mileages |

2014 Mazda CX-9 recalls
NHTSA's recall files of November 11, 2026 list 3 recall campaigns that name the 2014 Mazda CX-9. A campaign covers a production range, not every vehicle of the model year: check the VIN with NHTSA's free recall lookup.
What these figures can and cannot tell you
- Complaints are owners’ reports to NHTSA. NHTSA publishes them without verifying them: a complaint is an allegation, not a defect finding.
- The mileage is what the owner wrote on the complaint; NHTSA does not check it against the odometer.
- The make, model and model year are the ones on the complaint. NHTSA records them as filed, so a few complaints sit under a model year the name was not sold in.
- They are not a lifespan study. The file holds only vehicles whose owners reported a problem, so these figures do not say how long a typical 2014 CX-9 lasts.
- A complaint count rises with how many vehicles were sold and how long they have been on the road, so it is not a rating of the 2014 CX-9.
- Nothing here describes one vehicle: its title brands, odometer readings, accidents and open recalls are in the records for its own VIN.
- 26 of the 54 complaints on the 2014 Mazda CX-9 give no usable mileage (blank, zero, a filler such as 999999, or over 500,000) and are left out of every mileage figure.
- NHTSA names counted: CX-9 and CX9. NHTSA files some vehicles under several names (a series name and a trim name, for example); this page counts only these.
- Recall-file names matched: CX-9 and CX9.
