The second-generation Mazda CX-5, introduced in 2016, improved on the handling, cabin quality, fuel efficiency, and reliability of the previous-generation compact SUV.
Though improved, the newer Mazda CX-5 isn’t free from problems. There are a few common issues on the Mazda CX-5 worth knowing about if you own one or are considering buying a used one.
Common problems on 2nd-gen CX-5s:
Advice for buyers:
Below, we’ll explore seven common problems with the second-generation CX-5 and present a data-backed review of how reliable older versions are compared to newer models.
Here are some problems that might appear on a second-generation CX-5:
Some 2018–2020 CX-5s, especially those with a non-turbo 2.5 Skyactive engine with cylinder deactivation, developed cracks in the cylinder heads.
This is a serious problem that’s very expensive to remedy when the vehicle is out of warranty. It causes symptoms, such as oil leaks (on a non-turbo engine), coolant leaks (on a turbo engine), overheating, and misfiring.
Mazda revised the engine design starting with the 2021 CX-5, effectively resolving the issue.
Some Mazda CX-5 owners reported noticeable engine vibration at idle or during light acceleration, particularly with the 2.5L engine. This is often related to worn motor mounts, carbon buildup in the intake system, or faulty ignition coils.
While not a huge issue, this can cause drivability hiccups and daily annoyances. Regular maintenance and fuel system cleaning can usually keep this common issue under control.
The Mazda Connect system brings driver-assist features, navigation, Bluetooth, and smartphone integration (Android Auto and Apple CarPlay) into one touchscreen interface.
However, many CX-5 owners have reported malfunctions like:
Software updates may resolve these bugs, but in some cases, you may need to replace the infotainment control unit. Keeping your system updated through regular service intervals helps maintain connectivity.
NOTE: Android Auto and Apple CarPlay support (without manual installation) was only added for the 2019 model and wasn’t included for all trims until 2021.
Early second-gen model years (2017 and 2018) have some common electrical problems, like:
Many of these are minor, intermittent, and easy to resolve with prompt diagnostics and component replacement.
While the CX-5 delivers decent braking performance, some owners of earlier models reported increased brake pad wear.
This is often linked to higher-friction brake compounds used to provide strong stopping power, which can wear out faster, especially in heavy stop-and-go driving.
Drivers may hear squealing or feel pulsation through the brake pedal due to a heat-warped rotor. Replacing affected pads and rotors with high-quality components helps maintain consistent braking performance.
Some CX-5 owners have reported transmission hesitation, harsh downshifts, or delayed engagement when accelerating from a stop.
The problem typically appears in vehicles with neglected fluid changes or outdated transmission control software.
Mazda has issued service bulletins addressing some of these drivability complaints, emphasizing the importance of regular maintenance and fluid changes.
The CX-5’s paint options, especially their iconic metallic red and carbon edition, look impressive but have been reported to chip or scratch easily. Prolonged sun exposure without protection can also dull the finish.
This common issue is largely cosmetic, but Mazda CX-5 owners who care about resale value or appearance should consider regular detailing or car covers to preserve the vehicle’s exterior.
Now, you may wonder: Do newer Mazda CX-5 models have fewer problems?
Let’s explore some year-specific differences.
The second-generation CX-5 generally has strong overall reliability compared to other vehicle makes and models.
However, some evidence suggests that 2018–2020 CX-5 models have more problems than other second-generation model years.
Here’s some data comparing the Mazda CX-5 reliability for different model years:
The 2018 CX-5 model year has the highest number of complaints to the National Highway Traffic Safety Administration (NHTSA). It’s followed by the 2019 model year, which also has a high complaint rate. While the 2020 model received fewer complaints, it was still affected by cracked cylinder head engine problems.
More recent Mazda CX-5 models can be harder to evaluate based on complaint volume, as reports trickle in over time. That’s why looking at complaints per year can be helpful. So far, the 2022–2025 model years have the lowest complaint rates.
Model YearNumber of NHTSA ComplaintsEstimated Complaint Rate2017141~18.3/year2018232~30/year2019229~52.7/year202094~20.7/year2021128~20/year202245~9.7/year202345~15/year202425~12.5/year20258~8/yearMazda has issued four recalls affecting the second-generation CX-5, all relating to 2017, 2018, or 2019 models:
So, do older CX-5s have a reliability issue, and is a newer model really better?
Here’s what independent organizations like J.D. Power and Consumer Reports say about the model’s dependability:
Despite early second-generation CX-5s having more issues and complaints, we don’t classify them as “models to avoid at all costs”.
The average annual repair cost for a Mazda CX-5 (all model years) is $450. Meanwhile, the repair costs for the 2017 and 2018 CX-5 are both under $400. This indicates that 2nd-generation CX-5s are more reliable than the previous generation.
Additionally, the repair cost for the CX-5 is far below the average cost for all vehicle models, which is $650.
So, any second-generation Mazda CX-5 seems to be a solid choice for a compact SUV in 2026. However, if you’re buying a used car, you’ll want to thoroughly inspect its condition.
Here’s what to look out for when buying a used CX-5:
It’s usually easy to tell when a vehicle has been properly maintained or neglected. Let’s explore why routine maintenance is so crucial.
Following the Mazda CX-5 maintenance schedule is the best way to prevent many common issues from becoming an expensive car problem. It’s also necessary for warranty compliance on new and certified pre-owned vehicles.
Oil changes every 7,500 miles, fluid inspections, tire rotations, and filter replacements all keep the engine and drivetrain healthy.
For turbo-engine models, sticking to premium fuel and shorter oil-change intervals can also help protect engine components, preventing a more serious reliability issue.
