The Mazda CX-5 is one of the most popular mid-size SUVs on Australian roads. Known for its stylish design, smooth handling, and overall reliability, it’s a top choice for families and daily drivers alike. But like any car, the CX-5 isn’t without its issues. If you’re considering buying one—or already own one—it’s worth being aware of some of the common Mazda CX-5 problems in Australia.
Engine and Diesel DPF Issues (Especially 2012–2016 Models)
Owners of early diesel-powered CX-5 models (especially from 2012 to 2016) have reported significant problems with the Diesel Particulate Filter (DPF). In many cases, the DPF warning light appears too frequently, or the system fails to regenerate properly during short urban drives. This leads to clogging, poor performance, and costly repairs if not addressed quickly.
Another common issue is excessive oil dilution in diesel engines—caused when unburnt fuel mixes with engine oil, which can affect lubrication and shorten engine life. Mazda updated the software in later models to improve DPF management, but it’s still something to watch out for, particularly in second-hand cars.
Infotainment and Connectivity Problems
The infotainment system in earlier CX-5 models (particularly 2013–2017) has caused frustration for many Aussie drivers. Complaints include frozen screens, unresponsive touch controls, and Bluetooth connection failures. While these may not impact driving directly, they do affect overall comfort and convenience—especially on long trips.
Suspension and Noise Complaints
Some owners of 2017–2020 Mazda CX-5 models have reported suspension issues, particularly a clunking noise from the rear. This can be linked to worn-out bushings or shock absorbers. There have also been complaints about excessive road noise, which is noticeable at highway speeds. While not dangerous, these problems can make the driving experience less enjoyable.
Lock and Key System Issues
Among the Mazda CX-5 problems in Australia, lock and key system malfunctions have become increasingly common, especially in models from 2014 to 2021. Drivers have reported keyless entry failures, dead key fobs, and trouble with the push-button start system. These issues often appear without warning and can leave you locked out of your car or unable to start it.
In such situations, a car key replacement may be necessary—and it’s crucial to contact a professional Mazda locksmith who understands the security systems in newer Mazda vehicles. Many newer CX-5 models come with smart key technology, so dealing with the wrong technician can cause more harm than good.
Transmission and Gearbox Concerns
Some CX-5 owners (particularly with the 2018 and 2019 models) have reported jerky gear changes or delayed shifting. While the automatic transmission in these vehicles is generally reliable, there have been isolated reports of software glitches or faulty sensors causing performance issues. If your CX-5 is experiencing rough shifts or hesitation, it’s worth having it checked early.
Paint and Interior Wear
Another minor but frequent complaint relates to premature paint fading, especially in darker colors like Soul Red and Deep Crystal Blue. Interior materials, like the leather on steering wheels and seat bolsters, also seem to wear faster than expected—often visible by the time the car hits 60,000 km.
Final Thoughts
Despite these concerns, the Mazda CX-5 remains a solid choice in the Australian SUV market. Regular servicing, software updates, and prompt attention to small issues can go a long way in keeping your CX-5 running smoothly.
However, it’s important for Aussie car owners and buyers to stay informed about Mazda CX-5 problems in Australia, particularly if you’re shopping for a used model. Knowing what to look out for can help you make smarter decisions and avoid unexpected repair bills.
