Honda CR-V vs Mazda CX-5: which is the better used buy?

On DVSA MOT records the Honda CR-V is the more reliable used buy: it passes its first MOT 6.0 percentage points more often than the Mazda CX-5 once both are compared against what the national fleet scores at the same age. That comparison covers 27,530 real tests, not a survey.

MOT first-time pass rate

Counted from DVSA’s anonymised MOT test records. “vs age-matched” compares each model against what the national fleet scores at the same age — the only fair better-or-worse number, because an older fleet fails more whatever its build quality.

Honda CR-V

Mk5, 2018–2023 (Hybrid) · mid-size family SUV

The Mk5 Honda CR-V (2018–2023) is among the most reliable mid-size SUVs in the UK. The dominant issue is oil dilution with fuel on early petrol-hybrid 1.5 VTEC Turbo — Honda issued a software fix in 2019. Post-2019 examples are largely problem-free. The hybrid (e:HEV) is exceptionally low-maintenance. Best-buy years: 2020–2023. Worst: 2018–early 2019 1.5T.

What goes wrong

1.5 VTEC Turbo fuel-in-oil dilutionmajor
Engine oil level rising above max on dipstick; oil smells of petrol; reduced oil viscosity
2018–early 2019 (1.5T petrol) · ECU update was free under Honda warranty; post-warranty oil damage: £800–£2,500 depending on severity
Check: Dipstick at viewing — oil level should not be above max. Ask seller for proof that Honda ECU update was applied. Service history should show Honda-stamp servicing with evidence of oil changes at correct intervals. Avoid cars that sat in short-trip urban use without the ECU fix.
e:HEV inverter (hybrid models)moderate
"System Error" or "IMA" warning; reduced power; rare fail-to-start
2018–2021 hybrid · Under warranty typically (Honda 5-yr hybrid warranty); out of warranty £1,800–£3,200
Check: Scan for hybrid system codes. EV-mode should engage cleanly at low speeds — if it never enters EV mode, inverter or battery may have faulted.
Infotainment — Honda Connect touchscreen freezesminor
Screen unresponsive; Apple CarPlay drops; reboot via long-press needed
2018–2021 · Free software update at Honda dealer
Check: Connect phone via Apple CarPlay and use for 15 minutes during test drive. Pre-2022 software update caused frequent drops.
Rear differential (AWD, pre-2021)moderate
Shudder under tight low-speed turns; AWD light warning
2018–2020 AWD variants · £350–£600 rear-diff fluid change + calibration; £1,200+ if actuator faulty
Check: Tight low-speed figure-of-eight during test drive — any shudder or groan means the rear diff fluid has never been changed. Service history must show diff fluid at 30,000 miles intervals.

Typical asking price:: £9,000–£26,000 (2018–2023; hybrid AWD variants at the top end)
Real-world economy:: 1.5T petrol: 31–38 mpg real-world. e:HEV hybrid: 42–49 mpg — significantly better on UK city/suburban use
Vehicle tax:: £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).
Best years:: 2020, 2021, 2022, 2023
Years to avoid:: 2018, early 2019

Mazda CX-5

KF, 2017–2024 (2022 facelift) · mid-size family SUV

The KF Mazda CX-5 (2017–2024) is one of the more reliable mid-size SUVs sold in the UK, but the dominant 2.2 SkyActiv-D diesel suffers fuel-in-oil dilution and DPF blockage on short urban journeys. Pre-2022 cars also have headlight clouding and dated Mazda Connect infotainment. Best-buy years: 2022–2024 (facelift). Worst: 2018.

What goes wrong

Engine — 2.2 SkyActiv-D fuel-in-oil dilutionmajor
Engine oil level rising above max on dipstick; diesel smell on dipstick; reduced oil viscosity; in extreme cases runaway-engine risk
2017–2021 (pre-software update); risk persists on any 2.2D used mainly for short urban trips · £180–£280 oil + filter change at independent specialist; £700+ if injector seals also need replacement
Check: Dipstick at viewing — oil level should be at or below max, not above. Sniff the dipstick for diesel. Ask the seller for the typical journey length: a 2.2D used mostly for sub-9 miles commutes is a red flag regardless of mileage.
DPF — 2.2 SkyActiv-D diesel particulate filtermajor
Limp mode; "DPF full" warning; loss of power on hills; failed regeneration cycles
All 2.2 SkyActiv-D, mileage- and usage-dependent · Typical issue 55,000+ miles when used for short urban journeys · £600–£1,200 forced regen + cleaning; £1,800–£3,000 DPF replacement
Check: Ask the seller for proof of recent motorway driving. Run a 30-minute mixed-speed test drive with an OBD reader connected (£20 phone tool) — watch DPF soot load. Avoid any car where the DPF has been removed or "remapped" — that voids the MOT and is a criminal offence in the UK.
Injector seal leakage (2.2 SkyActiv-D)moderate
Black sooty gunge around top of engine; diesel smell from bonnet area; rough idle on cold start
2017–2024 2.2D, more common above 60,000 miles · £200–£400 per injector seal kit + labour; £800–£1,200 if all four
Check: Pop the bonnet at viewing. Look at the cylinder head around each injector for black carbon staining — clean engine bay is the goal. Stained injectors mean leak in progress.
Headlight clouding (LED / HID lenses)minor
Milky-white or yellowed headlight lenses reducing beam pattern; failed MOT on light output
Pre-2022 facelift, all trims · Cosmetic — age-related, typically year 4+ · £120–£200 per lamp polish/refurb; £450–£700 per genuine Mazda LED unit replacement
Check: Visual inspection in daylight — lens should be clear, not foggy. Failed MOT on this fault is a common reason owners sell. Ask for last MOT certificate.

Typical asking price:: £12,000–£33,000 (2018–2024)
Real-world economy:: 2.2 SkyActiv-D 42–47 mpg real-world; 2.0 SkyActiv-G 31–35 mpg; 2.5 SkyActiv-G 28–33 mpg
Vehicle tax:: £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).
Best years:: 2022, 2023, 2024
Years to avoid:: 2018

Which one suits you

Honda CR-V

Good for: Families wanting reliable Japanese quality in an SUV package. e:HEV hybrid is the pick for urban and suburban commuting — no plug needed, excellent real-world economy. Buyers with good service history documentation.

Less good for: Buyers tempted by early 1.5T examples without ECU-fix evidence; short-trip-only drivers on the 1.5T petrol; buyers needing 7 seats (CR-V is 5-seat only in UK spec).

Mazda CX-5

Good for: Family buyers wanting a premium-feeling Japanese SUV with strong long-term reliability, lower depreciation than German rivals, and a quiet refined cabin (especially post-2022 facelift). Best fit for drivers doing regular motorway miles.

Less good for: Short-trip city-only drivers buying the 2.2 SkyActiv-D — fuel-in-oil dilution and DPF clogging are use-pattern issues, not luck. Choose the 2.0 / 2.5 SkyActiv-G petrol or look elsewhere. Also not for buyers needing seven seats — CX-5 is strictly five-seat.

Which years should I avoid?

For the Honda CR-V, Early 2018–2019 1.5 VTEC Turbo engines reported fuel mixing into the engine oil in cold-weather short-trip driving patterns — exactly how many UK commuters use their cars. Oil level would rise above max and engine longevity was compromised in severe cases. Honda addressed it via ECU update, but pre-fix cars in the UK sometimes had the problem go undetected for months. For the Mazda CX-5, 2018 examples — the first full UK model year for the KF — saw the highest count of engine-related owner complaints, including oil leaks, oil consumption, and earliest reports of fuel-in-oil dilution on the 2.2 SkyActiv-D. Pre-update Mazda Connect was already feeling dated. Auto Reliability Index scores 2018 KF at 71/100 versus 87/100 for the 2022 facelift.

Which is cheaper to run?

The Honda CR-V returns 1.5T petrol: 31–38 mpg real-world. e:HEV hybrid: 42–49 mpg — significantly better on UK city/suburban use in real UK driving; the Mazda CX-5 returns 2.2 SkyActiv-D 42–47 mpg real-world; 2.0 SkyActiv-G 31–35 mpg; 2.5 SkyActiv-G 28–33 mpg. Vehicle tax: CR-V — £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025. Cars registered 2001–2017 pay a CO2 band, roughly £20–£790/year (2026/27 rates).; CX-5 — £200/year standard rate from the second year, hybrids included — the alternative-fuel discount ended on 1 April 2025.
