- Some dealership experiences often less than stellar.
Stuff you should know
- Released in Australia in July 2016, the second-generation Mazda TC CX-9 was a seven-seat SUV designed to offer practicality, comfort, and a premium driving experience. Manufactured in Japan, it was powered by a 2.5-litre turbocharged four-cylinder petrol engine. This engine, paired exclusively with a six-speed automatic transmission, was available with either front-wheel drive or Mazda’s on-demand all-wheel drive system.
- At launch, the CX-9 range included the Sport, Touring, GT, and Azami variants, with the luxury-focused Azami positioned at the top. In September 2018, Mazda introduced the Azami LE, offering even more premium features, including second-row captain’s chairs, further reinforcing the CX-9’s role as a viable alternative to luxury SUVs. Throughout its production run, the CX-9 received several mid-cycle updates, including improved noise, vibration, and harshness (NVH) levels in 2017, the addition of Apple CarPlay and Android Auto in 2018, further technology upgrades in 2021, and slight equipment and pricing adjustments in 2022.
- No matter which model year, all CX-9s feature the same 2.5-litre turbocharged engine, offering strong mid-range torque and smooth power delivery.
- While the AWD system provides extra traction when needed, the FWD variants offer better efficiency and lower running costs, making them a great option for those who don’t require AWD capability. Unlike some competitors, such as the Kia Sorento and Hyundai Santa Fe, all CX-9 trim levels—except the limited-run 100th Anniversary edition—were available in both FWD and AWD configurations, giving buyers more flexibility.
- Even the base Sport models were well-equipped with modern safety and technology features, while mid-tier models like the Touring and GT added premium touches such as leather upholstery and a higher-end audio system. The Azami and Azami LE took the CX-9 into luxury territory with Nappa leather, ventilated seats, real wood trim, adaptive cruise control, and in the LE, second-row captain’s chairs.
- The CX-9 positioned itself as a premium alternative to mainstream large SUVs like the Toyota Kluger, Kia Sorento, and Hyundai Santa Fe.
- Not only did it offer a more refined driving experience and a near-luxury feel, but it also held its value exceptionally well. Reports show that the CX-9 retains an impressive value on average, outperforming even the Toyota Kluger and far exceeding many European rivals.
- While Mazda has an excellent reputation for reliability and build quality, the CX-9 is not entirely without issues. Reports of cracked engine cylinder heads and cracked blocks have surfaced in some cases. We cover these potential concerns in more detail in our “What Goes Wrong” section.
What goes wrong
Exterior:
- The most common exterior complaint from owners is the failure of the power-folding mirrors, with many reporting that they either stop folding in or out. Fortunately, in most cases, this issue has been resolved under warranty.
- Like most Mazdas, the paint—especially in Soul Red—is prone to scratching easily, and according to panel beaters, it can be a nightmare to match if repairs are needed.
- Some owners have also reported that the gloss black plastic trim on the exterior is easily scratched, making paint protection film a worthwhile consideration.
- Being a large SUV weighing close to two tonnes, the CX-9 can be heavy on brakes, particularly if driven spiritedly. This means brake pads and discs may wear out quicker than expected. While OEM Mazda replacements are available, they come at a premium, and aftermarket options can often provide similar or even better performance at a lower cost.
Interior:
- One of the most widely reported issues is the infotainment screen developing cracks or a spider-web effect. Some owners have had their screens replaced under warranty—even just outside the warranty period—while others have not been so fortunate.
- On this, Mazda’s aftersales support appears to be inconsistent, with some customers reporting excellent service while others describe their experience as frustrating.
- Infotainment issues extend beyond screen durability, especially in pre-2021 models, where users have complained about laggy response times, long boot-up sequences, and Bluetooth or smartphone connectivity frequently dropping out.
- While the post-2021 update improved many of these issues, the system is still not without its faults.
- Additionally, the gloss black interior trim is highly prone to scratches, to the point where even light contact can leave marks. Some owners have opted to cover or replace these panels, but using the right cleaning products can help maintain their appearance.
- There’s also a curious issue with the front wireless phone charger, which reportedly struggles to charge devices properly—only maintaining battery levels rather than increasing them. Interestingly, rear-seat USB ports appear to provide significantly better charging performance, which has been a frequent complaint among owners.
Mechanically:
- While there have been reports of head gaskets and cylinder heads cracking, this issue is most commonly associated with 2016-2020 models. Despite some online discussions suggesting a widespread problem, the failure rate appears to be relatively low when compared to the number of CX-9s sold.
- However, for those affected, it can be a serious and costly issue. A telltale sign of trouble is coolant spraying from the back of the engine near the turbo. This can sometimes be misdiagnosed as a leaking turbo coolant hose or bypass hose, but in

This can sometimes be misdiagnosed as a leaking turbo coolant hose or bypass hose, but in severe cases, it could require replacing the cylinder head or even the entire engine. Warranty coverage has been inconsistent, varying by region and individual case. Some theories suggest that the weight of the turbo and exhaust system contributes to the problem, while others point to a weakness in the head or gasket design.
- For those tackling repairs themselves or via independent workshops, it’s worth noting that the plastic vacuum fitting on the back of the turbo is fragile and should be handled with care.
- There have been some reports of post-2021 models experiencing high oil consumption due to valve stem seal issues, though this appears to be quite rare.
- Additionally, EGR system complications can arise, typically caused by the valve sticking open, leading to a rough idle.
- Some high- and low-pressure fuel pump issues have been documented, but these are not widespread.
- Ultimately, provided the CX-9 has been well-maintained and serviced regularly, it is regarded as a reliable vehicle overall.

Should you buy it?
If you’re considering a used CX-9, we’d say yes—but with a few important conditions.
A thorough pre-purchase inspection is essential, and ensuring the car has a full and up-to-date service history is just as critical. Ideally, aim for the best-condition, lowest kilometre, most recent example you can find (and afford), preferably with as much factory warranty remaining as possible.
The main concern with these cars revolves around potential engine issues, but despite what the internet might suggest, failures don’t seem to be as widespread as some forums and reports make them out to be. And in cases where problems have occurred, Mazda has generally been responsive in addressing them under warranty.
For the vast majority of owners, the CX-9 has been a fantastic SUV, offering a well-rounded blend of practicality, performance, and comfort. It may not be the absolute class leader in any one category, but it does so many things exceptionally well that it’s hard to fault. And with Mazda boasting one of the highest customer retention rates in the industry, that should provide some extra confidence when making a purchase.
