Hyundai Tucson vs Mazda CX-5: which is the better used buy?

On DVSA MOT records the Hyundai Tucson and the Mazda CX-5 are too close to call — 0.5 percentage points apart on first-time MOT passes once you allow for the age of each fleet, which is inside what the choice of cars counted can move. A winner is named only at 2 points or more. A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure.

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.

These figures count every generation still on the road, not only the one described below: mostly Hyundai Tucsons registered 2015–2022 and Mazda CX-5s registered 2013–2022.

Source: DVSA MOT Anonymised Data 2025 (Open Government Licence v3.0). National first-time pass rate 77.3%. Class 4 tests in Great Britain, test type NT (a normal annual test), retests excluded. A pass, or a pass with rectification at the station, counts as a first-time pass; DVSA's own initial-test measure counts a rectified pass as a failure and so reports a lower figure. Testing in Northern Ireland is run separately by the DVA under its own rules. The difference is worked out before rounding, so it can be 0.1 away from the two rounded figures beside it.

Hyundai Tucson

NX4, 2020+ · compact crossover SUV

The NX4 Hyundai Tucson (2020+) is a fixture of the UK's top ten best-sellers and broadly reliable. Concerns: 1.6 T-GDI smart-stream engine had early oil-consumption claims (largely settled), PHEV battery cooling pump issues, and pre-2023 infotainment freezes. Long warranty mitigates most risk. Best-buy: 2023+. Worst: no single year stands out on DVSA MOT results.

What goes wrong

  • 1.6 T-GDI smart-stream oil consumptionmoderate
    Oil level drops between services; rough idle; rare warning
    2020–2022 1.6 T-GDI · Often goodwill from Hyundai UK under 5-yr warranty; out-of-warranty engine rebuild £3,500+
    Check: Dipstick at viewing. Service history: any oil top-ups recorded? Hyundai goodwill claim history.
  • PHEV battery cooling pumpmajor
    "Hybrid system" warning; battery thermal management warning; reduced EV range
    2021–2022 PHEV (Hyundai UK launched the Tucson plug-in hybrid in March 2021) · Under warranty within 5 years; out of warranty £1,200+
    Check: PHEV battery health check at Hyundai dealer (£30–£50). Compare the EV-only range the car shows on a full charge with the official WLTP electric range for that model: a large shortfall on a mild day suggests the battery has degraded.
  • Infotainment freezesminor

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

  • Safety recall R/2019/187recall
    Soot may accumulate around the intake shutter valve on the inlet side of the engine

  • 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 tampered with: under the DVSA MOT inspection manual (8.2.2.1) a missing or tampered-with DPF is a major defect, which fails the MOT, and GOV.UK says removing one is almost always illegal.
Typical asking price:

A car registered from April 2017 with a list price over £40,000 when new adds the £440/year Expensive Car Supplement in years 2–6 (£640 in all).

Which one suits you

Hyundai Tucson

Good for: Family buyers wanting low-stress modern SUV with Hyundai's 5-year unlimited-mileage warranty (within service-record terms).

Less good for: Buyers needing premium badge feel; very high-mileage motorway commuters (diesel alternatives more efficient).

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.

Frequently Asked Questions

Which is more reliable, the Hyundai Tucson or the Mazda CX-5?
Neither stands out on the MOT measure. Their first-time MOT pass rates sit 0.5 percentage points apart once each is compared against the national rate for cars of the same age, which is too close to call (we name a winner only at 2 points or more). A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure. The MOT checks safety and emissions items, not the engine, clutch or gearbox, so this is one measure of how each car holds up rather than a full reliability verdict. Pick on the specific faults each is prone to instead.
How do the MOT pass rates of the Hyundai Tucson and the Mazda CX-5 compare?
85.3% of Hyundai Tucsons pass their MOT first time (17,402 tests in DVSA's records) and 83.2% of Mazda CX-5s pass their MOT first time (7,514 tests). The national first-time rate is 77.3%, but cars of the Hyundai Tucson's age average 85.2% and cars of the Mazda CX-5's age 82.7% — so the Hyundai Tucson runs level with its age group and the Mazda CX-5 runs 0.5 points better than its own. A pass with rectification at the station counts as a pass here, and as a failure in DVSA's own initial-test measure.
Which years of the Hyundai Tucson and Mazda CX-5 should I avoid?
Hyundai Tucson: The first UK plug-in hybrids arrived in spring 2021, and those early cars are the ones owners most often report battery cooling pump faults on. How often it happens is not known. The DVSA MOT table on this page rates 2021 registrations above all cars registered that year, so it is not named as a year to avoid. Judge a Tucson by its registration, service history and the checks below rather than by year. 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.
Is the Hyundai Tucson or the Mazda CX-5 cheaper to run?
On fuel the two are too close to call: the most economical versions return up to 49 mpg (Hyundai Tucson) and 47 mpg (Mazda CX-5), on the figures in our model guides. For cars registered from April 2017, vehicle tax works the same way for both: the £200/year standard rate from the second year, hybrids included, plus the £440/year Expensive Car Supplement in years 2–6 on a car that listed at over £40,000 new — the price when new, not what you pay for it used. Any Hyundai Tucson or Mazda CX-5 registered between 1 March 2001 and 31 March 2017 pays a CO2 band instead, roughly £20–£790/year (2026/27 rates). Insurance differs mainly by driver and postcode rather than by model, so treat any model-level insurance figure with caution.

MOT figures are counted from DVSA records and are the only measured statistic here. Prices, economy and tax bands are indicative and vary by specification, condition and where the car has lived. Last reviewed: 2026-10-06 / 2026-10-06.
