Mazda introduced an all-new CX-9 to the market for model-year 2016, offering shoppers a 3-row midsize crossover to compete with models like the Toyota Highlander, Honda Pilot, and GMC Acadia. Setting itself apart, however, the CX-9 impressed with its upscale interior, high-torque turbo engine, and KODO-inspired styling.
Designed with mature families in mind, the CX-9 was built to be decidedly sophisticated, and many shoppers chose this model as a more affordable alternative to a family crossover from more upscale brands.
Shoppers will find a full array of advanced safety equipment via Mazda’s array of i-ACTIVESENSE features, as well as a predictive AWD system and standard 2.5-litre turbo SKYACTIV engine built for strong low-rev response and fuel efficiency figures. Look for a BOSE stereo system, premium lighting provisions, a heated steering wheel, available wood trim, Mazda’s active driving display HUD, Radar Cruise, advanced blind spot monitoring, a power tailgate, Smart Brake Support, and automatic high beams.
Owners tend to like the CX-9’s rich and colourful cabin, respectable mileage, and ride comfort that stands up well to rougher surfaces. Still, some may desire greater ground clearance at the front of the vehicle while tackling trails and deep snow, and taller drivers may wish for a taller door opening.
Check out the related links and stories for more reviews, news, specs, and other Mazda CX-9 related info, and read on for 5 tips to help make sure you find the best used Mazda CX-9 possible for your dollar.
Tip 1: COVID issues, ‘lot rot’
Shoppers buying a used car during the global pandemic are faced with a few additional risks, as vehicles are more likely to have been sitting for extended periods in driveways and dealer lots.
Certain problems become more likely when vehicles aren’t driven for an extended period, including flat-spotted tires, braking system corrosion, battery decay, and rodent-related damage. Each of these issues can result in a headache or unwanted expense. Vehicles stored on dealer lots for extended periods may be at higher risk of body, paint and wheel damage from being shuffled around the lot as well.
Be on the lookout for trouble signs during your test drive: unwanted noises and vibrations (especially while braking), an unwelcome roaring or shuddering sensation from the vehicle while cruising, warning lights or error messages in the instrument cluster, and excessive damage, wear, or rust to painted surfaces.
Confirming proper battery health via a professional inspection is also highly advised, as a fresh and healthy battery (if required) can fend off trouble across an array of vehicle systems.
If in doubt, get it checked out — ideally by a Mazda-trained technician — before you buy.

Tip 2: Infotainment
Infotainment system problems are some of the most commonly reported among all used vehicles these days, and the Mazda CX-9 is no exception. Some owners have reported trouble, most commonly around an infotainment system that randomly reboots itself, which can take the system offline for several minutes. Many have not.
In many cases, infotainment system trouble like this is a matter of software, not hardware. This means that the fix often involves having dealers install updated system firmware to the central head unit, like updating the operating system on your phone or laptop. Many owners have reported an infotainment system firmware update to be a successful fix, so start there if you notice any trouble.
Other owners have identified the navigation system SD memory card as a possible issue. Especially in cold temperatures, the physical contacts between this memory card and the reader built into the head unit may not connect properly and lead to issues.
Do not attempt to remedy a wonky infotainment system by unplugging and disconnecting the CX-9’s battery without consulting with a professional. Further, remember to check for an adequate number of charging ports and USB inputs, and outdated navigation system maps.

Tip 3: Air conditioner checkup
A commonly discussed problem amongst CX-9 owners from this generation is poor performance of the air conditioner system.
According to some owners, the air conditioner is weaker than expected, and may struggle to adequately cool the cabin in certain situations, especially when driving at low speeds. Other owners report no issue, and give the CX-9’s AC system high marks.
There’s some consensus among owners that the CX-9’s air conditioner isn’t a strong performer, though reports are fairly inconclusive against total sales volume. On your test-drive, run the system through its paces, confirming that there are no obvious signs of system failure such as a total lack of cool air.
Blast the A/C and drive the vehicle around, confirming that the selected air temperature is delivered consistently. If warm air appears without a corresponding change in the temperature selector, proceed with caution and have the vehicle seen by a professional before you buy. Air conditioner performance problems can also be a sign of pricier issues, including refrigerant leaks, system electronic trouble, or broken or malfunctioning system hardware, some of which requires slow and costly dashboard removal to fix.
A clogged cabin air filter, clogged A/C condenser, or clogged cabin air intake are other leading causes of climate control system trouble. Having the air conditioner in the CX-9 you’re considering inspected before you buy can save you money and headaches.
Some owners report that the use of UV-blocking aftermarket window tint can help keep the cabin cooler, reducing the load on the A/C system.

Tip 4: Check 2017’s for this problem and recall
Mazda recalled several thousand CX-9’s from model-year 2017 to address potentially serious issues caused by a faulty wiring harness.
The wiring harness is the CX-9’s electronic nervous system. A multitude of modules, computers, and hardware are connected through an array of wires, with numerous junction points where various wiring bundles are plugged into each other.
Some 2017 model-year units may have been built with a faulty wiring harness using clips that fail to keep various parts of the wiring harness properly plugged in to one another. If one or more sections of the wiring harness become disconnected, numerous random and wide-reaching problems with vehicle electronics are experienced, some of which are severe and dramatic.
Many sellers of 2017 CX-9’s have already had recall work completed to address the issue. Still, as this problem can result in frustrating issues and even stop your road-trip dead in its tracks, check with a dealership to confirm that the recall work has been completed for maximum peace of mind.

Tip 5: Turbo engine care
If a used CX-9 might be your first vehicle running a modern turbocharged engine with direct injection, here’s a friendly reminder of a few tips that can help that engine run reliably for the long-term.
First, be sure to fuel up using only quality gasoline from a reputable retailer you trust. Higher-tier rated gasolines are best, as they can contain additional detergents and additives that help keep fuel system components clean and lubricated.
Top-tier gasoline is available in all octane levels. The Mazda CX-9’s engine does not require premium high-octane gasoline and is engineered to run on regular-grade gas, saving owners money when they fill up. Still, the engine is able to benefit from higher-octane gas should owners decide to use it.
In fact, the CX-9 has two horsepower ratings — 227 on regular gas, and 250 on premium. Premium fuel is not required, but it does allow this engine to deliver more power and significantly more torque.

Further, be sure to have oil changes performed on time, using only factory-approved oil and filters as outlined in the owner’s manual. This is vital for long engine life, maximum efficiency, and to keep the CX-9’s warranty in good standing. Ensuring that spark plugs are changed at or before their required intervals can help fend off potential trouble as the engine ages, too. Note that most Canadian drivers should follow the ‘severe’ service schedule in the owner’s manual.
Final Thought
These tips are designed to help test-driving shoppers more easily identify possible trouble areas reported by some owners. An attentive test drive and shopping process that focuses on the areas above can help you find a first-class example of a second-hand Mazda CX-9.
