The Mazda CX 5 is the SUV for people who enjoy driving but need a family car. On sale since 2012 and Mazda’s best seller worldwide for years, it built its reputation by being the one family SUV that feels like a proper car on a winding road, with engines that are simple by modern standards and an interior that punches above its price.
So who does it suit? Drivers who want an SUV without the dull driving experience. Families who need five seats and a useful boot but refuse to buy something boring. Used buyers who want a reliable Japanese SUV that costs less to buy than a RAV4 of the same age.
People cross shop the CX 5 against the RAV4 and Tiguan. One thing to know before you read on: the engines are the whole story on this car, because the petrols are near bulletproof and the diesel needs a very specific kind of owner. This page covers the generations from 2012 onward, the engines worth having, the problems owners actually report, the years to buy, and what the car costs to run.
Mazda CX 5 at a glance
The quick facts first. Every CX 5 is a five door SUV with five seats, and the boot is a genuinely useful shape even if it is not the biggest in the class.

Generations explained
Three generations cover the CX 5 story, and the used market is really about the first two. Each generation has a distinct engine lineup, which is why the faults move with the generations too.
| Generation | Years | What changed |
|---|---|---|
| KE | 2012 to 2017 | The original. Simple 2.0 petrol and the 2.2 diesel, with the 2.5 petrol joining in 2014. Check any diesel carefully and confirm the liftgate recall was done. |
| KF | 2017 to 2025 | Sharper, quieter and plusher, with the 2.5 petrol, the 2.5 turbo from 2019 and a short lived US diesel. Watch the 2018 to 2019 rocker arm recall and oil use on the 2021 turbo. |
| Third generation | 2025 to present | Bigger car, new digital cabin, 2.5 litre mild hybrid petrol with 141 hp. Too new for used buying or long term verdicts. |
The KE car, sold from 2012 to 2017, is the budget buy. The 2.0 litre petrol with 155 hp in US spec cars or 160 to 165 hp in European cars is a simple, honest engine that asks for little. The 2.5 litre petrol with 184 to 192 hp joined in 2014 and is the stronger pick. The 2.2 diesel with 150 or 175 hp is economical but brings the DPF and injector risks the problems section covers. The 2015 and 2016 cars are the ones the guides call the safest of this generation, with the early faults sorted.
The KF car ran from 2017 to 2025 and is the one most used buyers will meet. It kept the winning formula but added refinement, better safety kit and the 2.5 litre turbo with 227 hp on regular fuel or 250 hp on premium in the US from the 2019 model year. Apple CarPlay and Android Auto arrived in 2019, so earlier cars feel dated. The late cars from 2021 to 2024 are the ones the guides recommend, with the sorted infotainment and standard safety kit.
Engines and specs that matter
The naturally aspirated petrols are the heart of the CX 5 story. The 2.0 litre Skyactiv G makes 155 hp in US spec cars or 160 to 165 hp in European cars, and it is a calm, simple engine with no turbo to worry about. The 2.5 litre Skyactiv G makes 184 hp in the early cars and 187 to 192 hp in the later ones, and it is the engine most reviewers recommend: stronger everywhere, barely thirstier, and famously durable. For most buyers, a 2.5 litre petrol CX 5 is the default right answer.
The 2.5 litre turbo is the fun one. Added for the 2019 model year in the US, it makes 227 hp and 310 lb ft of torque on regular fuel, or 250 hp and 310 lb ft on premium. It turns the CX 5 into a genuinely quick family SUV with effortless overtaking pace. The trade off is fuel economy and the 2021 oil consumption issue covered below, so check the oil history before you fall for the performance.
The 2.2 litre diesel needs a frank paragraph. With 150 or 175 hp and up to 420 Nm of torque in Europe, or 168 hp and 290 lb ft in the brief US run for the 2019 model year, it is economical on long runs. But the diesel particulate filter needs regular long drives to clean itself, and short trip cars suffer blocked filters, fuel leaking into the oil so the level rises on the dipstick, and leaking injector seals that let soot into the oil, which can turn it to sludge and damage the camshaft and turbo. Buy the diesel only if you do long journeys regularly and the service history is perfect. Otherwise the petrol is much less stress.
Gearboxes are refreshingly simple. Almost every CX 5 uses Mazda’s 6 speed Skyactiv Drive automatic, a conventional torque converter automatic that is widely praised for reliability and needs no heroic maintenance. Some early European 2.0 petrol and 2.2 diesel cars had a 6 speed manual. There is no troublesome dual clutch here, which is one of the CX 5’s quiet advantages, and our guide on how often to change transmission fluid explains what a sensible gearbox service looks like on a high mileage car.
Which engine suits you? Want the safest used buy, take a 2.5 litre petrol. Want the cheapest to run in town, the 2.0 petrol is fine. Want pace, the 2.5 turbo from 2019 is a delight but check the oil history on 2021 cars. Do big motorway miles and like diesels, the 2.2 diesel works only with long journeys and full Mazda service records. On a test drive of any diesel, pull the dipstick and check the oil level is not above the maximum mark, because rising oil level is the classic diesel warning sign.
Common problems by generation
The CX 5’s reputation is deserved, but the problems are engine specific, which means you can check for every one of them before you buy. These are the issues that come up again and again in owner reports, technical bulletins and buying guides.
KE, 2012 to 2017
Diesel DPF and injector problems on the 2.2 define the early car’s risk. Short trip diesels clog their particulate filters, interrupted regeneration dumps diesel fuel into the oil so the level rises on the dipstick, and leaking injector seals let soot into the oil which can turn it to sludge and damage the camshaft and turbo. On any diesel you consider, check the oil level yourself, look at the service history for oil changes done on time at a Mazda dealer, and walk away from any car with a DPF warning light on. The 2013 to 2016 cars were also recalled for the liftgate support struts, which could corrode and let the heavy tailgate drop unexpectedly, so confirm that recall was done. Early infotainment is slow and the 2012 to 2018 cars have no Apple CarPlay or Android Auto, which is a frustration rather than a fault.
KF, 2017 to 2025
The rocker arm recall is the big one for 2018 to 2019 cars. Mazda recalled these cars because a software fault in the cylinder deactivation system could let an intake valve rocker arm come out of position, causing misfires, loss of power or stalling. The fix is a free software update, and the recall notice says the malfunction indicator light may illuminate, which is exactly when our guide on a flashing check engine light tells you to stop driving and get the car checked. Confirm the recall is closed on any 2018 or 2019 car. Separately, certain 2021 cars with the 2.5 litre turbo were covered by Mazda’s warranty extension for excessive oil consumption caused by valve stem seals, with coverage extended to 7 years or 84,000 miles, so on a 2021 turbo check the oil level and ask for the oil consumption test history. Owner reports also mention cracked cylinder heads leaking oil on some 2018 to 2019 2.5 litre cars with cylinder deactivation, so look for oil seepage around the cylinder head on a pre purchase inspection. Auto folding side mirrors failing to open fully are a reported annoyance on 2019 cars.
Third generation, 2025 to present
Too new for a problems record. Early cars use a new mild hybrid system and a heavily digital cabin, so buy on warranty and keep every software update applied. Nothing here yet that should steer you away, but there is no used stock to speak of.
Which Mazda CX 5 should you buy
On a tight budget, look at a 2015 or 2016 KE with the 2.5 litre petrol. The guides call these the safest early cars: simple engines, the early faults sorted, and prices well below the KF. Avoid the early diesels unless the history is perfect.
In the middle ground, a 2020 to 2024 KF with the 2.5 litre petrol is the sweet spot. You get the refined cabin, CarPlay and Android Auto, the full safety kit and the sorted 6 speed automatic. Drivers who want pace should look at the 2.5 turbo from 2019, but check the 2021 cars for the oil consumption issue first.
Years to be careful with are 2012 to 2014 for the early diesel risks, 2018 to 2019 for the rocker arm recall, which you should only buy with proof the recall is done, and 2021 for the turbo oil consumption. The late cars of each generation are always the safer buy.
Whatever the generation, run through this checklist before you hand over money:
- On a diesel, pull the dipstick yourself and check the oil level is not above the maximum mark.
- Ask the seller directly whether the car does mostly short trips, and avoid a diesel that does.
- On a 2018 or 2019 car, confirm the rocker arm recall is closed using Mazda’s recall checker.
- On a 2021 turbo, check the oil level and ask about oil consumption history.
- On a 2013 to 2016 car, confirm the liftgate strut recall was done, then open the tailgate and let go to feel the struts hold it.
- Check the infotainment pairs with your phone. 2012 to 2018 cars have no CarPlay or Android Auto.
- Look at all four tyres for uneven wear, which points at alignment or suspension wear.
- Check the service history is complete and at proper intervals, especially on diesels.
Running and repair costs
Sensible running costs are a big part of the CX 5’s appeal. Parts are easy to find and every independent garage knows the Skyactiv engines. Our full breakdown of brake pad replacement cost shows what one of the most common jobs involves. Typical US prices for the common jobs look like this:
| Job | Typical cost in US dollars |
|---|---|
| Front brake pads, fitted | 150 to 300 |
| 12 volt battery, fitted | 150 to 250 |
| Four tyres, fitted | 450 to 900 |
| Major service at an independent garage | 300 to 600 |
| Valve stem seal repair, 2021 turbo | Covered under Mazda’s extended warranty to 7 years or 84,000 miles |
The diesel rows are missing from this table for a reason: a clogged DPF or a turbo damaged by diluted oil can run into the thousands, which is exactly why the buying advice keeps steering town drivers toward the petrols. The petrol cars are cheap and predictable to run.
Questions and answers
Is the Mazda CX 5 reliable?
Yes, and the petrol versions are among the most reliable family SUVs you can buy. The 2.0 and 2.5 litre petrol engines have outstanding records, and the 6 speed automatic is one of the toughest gearboxes in the class. The weak points are specific and avoidable: the 2.2 diesel on short trips, the 2018 to 2019 rocker arm recall and the 2021 turbo oil consumption. Buy a petrol with records and it is superb.
Which is the best CX 5 year to buy used?
For value, a 2020 to 2022 KF with the 2.5 litre petrol is the consensus sweet spot: refined, well equipped and with the early faults behind it. On a tighter budget, a 2015 or 2016 KE 2.5 petrol is honest cheap transport. If you want the pace of the turbo, the 2019 and 2020 cars sidestep the 2021 oil consumption issue.
Should I buy the CX 5 diesel or the petrol?
Buy the petrol unless almost all of your driving is long journeys. The diesel is economical on motorway runs but the DPF needs regular long drives to regenerate, and short trip diesels suffer blocked filters and fuel diluting the oil. For town and mixed driving the 2.5 petrol costs little more in fuel and much less in risk.
What is the rocker arm recall on the 2018 to 2019 CX 5?
It is a Mazda safety recall where a software fault in the cylinder deactivation system could let an intake valve rocker arm come out of position, causing misfires, loss of power or stalling. Mazda’s fix is a free powertrain control module software update. If you are considering a 2018 or 2019 car, run the VIN through Mazda’s recall checker and buy only with proof the recall is closed.
