Is the Toyota bZ4X reliable?

The Toyota bZ4X scores 95/100 on Forecourt's MOT-based reliability measure. That is computed from 15,144 real DVSA MOT test results.

How much does a used Toyota bZ4X cost?

A 2023 Toyota bZ4X with around 39,567 miles is worth roughly £17,750 today (typical range £15,200–£20,250). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.

How quickly does the Toyota bZ4X depreciate?

A new Toyota bZ4X typically loses about 57% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.

What insurance group is the Toyota bZ4X?

The Toyota bZ4X sits in insurance group 25 of 50 — the middle of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.

What goes wrong on a used Toyota bZ4X?

The most common age-related issues we track for the Toyota bZ4X are: tyres & wheels (typically around 60k-100k miles, £80-£500 to put right); suspension (typically around 60k-100k miles, £150-£450 to put right); driver's view (typically around 30k-60k miles, £60-£300 to put right). A full service history and a recent MOT with no advisories are the best protection.

What does the Toyota bZ4X cost to run?

Expect around 3.5 miles per kWh on the bZ4X 71 Motion FWD, £200 a year in road tax, about £185 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.

Is the Toyota bZ4X ULEZ compliant?

The Toyota bZ4X is pure-electric, so it is exempt from the London ULEZ charge and every other UK clean-air zone, whatever the registration year.

How many Toyota bZ4Xs are on UK roads?

About 12,336 Toyota bZ4Xs are currently taxed and on the road in the UK, from DfT vehicle-licensing data.

Toyota bZ4X

The Toyota bZ4X (2022 on) is Toyota's first bespoke electric SUV - a comfortable, easy-to-live-with family EV co-developed with Subaru (which sells it as the Solterra). It prioritises Toyota's usual reliability and refinement over pace or class-leading range. Charging speed and range are adequate rather than standout, but as a dependable, low-stress electric SUV with Toyota's reputation behind it, it's a sensible used choice.

How these figures are sourced — the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

The short version

50/100

Forecourt score

Value 2 · Reliability 98 · catalogue percentiles

The Toyota bZ4X loses value faster than most cars. Its MOT-based reliability is excellent — an MOT score of 95/100. On three-year value retention it ranks better than 2% of models.

The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20) — the from-new ownership picture. Higher is better; running cost is not yet folded in.

Flip side for used buyers: heavy depreciation is the first owner’s loss and the used buyer’s discount — a reliable car with a low score here can be a strong used purchase at today’s prices.

Safety rating

Euro NCAP's independent crash-test rating for the Toyota bZ4X, from its 2025 assessment.

5/5

TEST YEAR2025

Current rating · valid to 2031

The passenger compartment of the Toyota bz4X remained stable in the frontal offset test.

Independent crash-test data from Euro NCAP. Star ratings reflect the test protocol of the year shown — newer protocols are stricter, so a 5-star from 2024 represents a higher bar than a 5-star from 2014. Euro NCAP ratings run for six years from publication; a lapsed rating means the protocol has moved on, not that the car performs any worse than it did on test.

MOT outlook

How this model fares at its MOT as it ages — from 15,144 real DVSA test records.

MOT pass rate by age

95.4% at 3yr → 92.5% at 4yr

A 3-year-old bZ4X passes its MOT 95.4% of the time; by 4 years that has slipped to 92.5%. The y-axis is zoomed to this model’s range so the trend is readable.

Longevity

Not enough older examples yet to gauge longevity.

What fails at the first MOT

The defect categories a bZ4X registered 2022–2023 fails on at its first MOT, from 767 first tests. Every car here is the same age and the same generation, so these are the faults that show up first - not the wear a high-mileage older example collects.

Reliability

95/ 100

Excellent

First-MOT pass rate and defect rate for cars registered 2020 onward (767 first tests), with cohort survival — medium confidence.

MOT outlook

Insufficient MOT history at this car's reference age — too few tests to compute a reliable percentile.

Things owners say

01Range and charging are adequate rather than leading - fine for most, plan longer trips around it.
02Toyota's reliability reputation and a strong battery warranty are key reassurances - check the warranty applies.
03Comfortable and refined rather than sporty; the AWD version shares its system with the Subaru Solterra.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the Toyota bZ4X, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

Theft risk

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.

Whole-car theft

Higher

Desirable SUVs like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.

Parts theft

Lower

As an electric car it has no catalytic converter, so the most common parts-theft vector doesn't apply.

Worth doing

Keep keys in a Faraday pouch and away from the front door to block relay attacks.
A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.

Clean-air zones

Whether driving a Toyota bZ4X into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.

Charging zones for cars

City	Area	Daily charge	Likely outcome
London	All of Greater London (within the M25)	£12.50	Likely exempt Battery-electric — exempt everywhere.

Company car tax

What HMRC's Benefit-in-Kind charge looks like if you ran this Toyota bZ4X as a company car, by tax year and income-tax band. Calculated from a CO₂ of 0 g/km, using £50,000 as the P11D value.

EVs sit at the bottom BIK band — currently 4% — so this is one of the cheapest ways to take a company car.

Tax year	BIK %	Tax @ 20%	Tax @ 40%	Monthly @ 20%	Monthly @ 40%
2025-26	3%	£300	£600	£25	£50

2029-30	9%	£900	£1,800	£75	£150

P11D value is approximated from the latest new price; the exact figure on your tax code will depend on options fitted. The 4% diesel surcharge applies only to non-RDE2 (pre-2021) diesels — we assume RDE2 compliance for current models. Bands and rates from HMRC's Autumn Budget 2024 confirmation through 2029/30.

Common questions

Toyota bZ4X, answered from the data

Is the Toyota bZ4X reliable?: The Toyota bZ4X scores 95/100 on Forecourt's MOT-based reliability measure. That is computed from 15,144 real DVSA MOT test results.
How much does a used Toyota bZ4X cost?: A 2023 Toyota bZ4X with around 39,567 miles is worth roughly £17,750 today (typical range £15,200–£20,250). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
How quickly does the Toyota bZ4X depreciate?: A new Toyota bZ4X typically loses about 57% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.
What insurance group is the Toyota bZ4X?: The Toyota bZ4X sits in insurance group 25 of 50 — the middle of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.
What goes wrong on a used Toyota bZ4X?: The most common age-related issues we track for the Toyota bZ4X are: tyres & wheels (typically around 60k-100k miles, £80-£500 to put right); suspension (typically around 60k-100k miles, £150-£450 to put right); driver's view (typically around 30k-60k miles, £60-£300 to put right). A full service history and a recent MOT with no advisories are the best protection.
What does the Toyota bZ4X cost to run?: Expect around 3.5 miles per kWh on the bZ4X 71 Motion FWD, £200 a year in road tax, about £185 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.
Is the Toyota bZ4X ULEZ compliant?: The Toyota bZ4X is pure-electric, so it is exempt from the London ULEZ charge and every other UK clean-air zone, whatever the registration year.
How many Toyota bZ4Xs are on UK roads?: About 12,336 Toyota bZ4Xs are currently taxed and on the road in the UK, from DfT vehicle-licensing data.
