How many Toyota iQs are left in Great Britain?
There were 15,881 Toyota iQs licensed in Great Britain at the end of March 2026, and a further 752 declared off the road (SORN).
That is 15.2% fewer than the peak of 18,736 in 2014.
Toyota iQs licensed in Great Britain
Numbers peaked in 2014 and have fallen every year since, as older cars are scrapped faster than new ones are registered.
In 2025, 73.8% of Toyota iQ MOT tests were passed first time,
against 72.8% for all cars.
Cars of the same ages as the Toyota iQs tested pass 61.2% of the time, so the Toyota iQ does better than average for its age, by 12.6 points. In 2024 its pass rate was 75.2%.

Lamps, reflectors and electrical equipment is the most common reason a Toyota iQ fails its MOT,
appearing on 43.2% of failed tests. A failed test can have defects in
more than one category, so shares add up to more than 100%.
5.0% of Toyota iQ tests found at least one dangerous defect, against 7.3% for all cars.

The single most common reason a Toyota iQ failed its MOT in 2025 was
“Position lamp: not working”, on 13.2% of 4,350 failed tests.
53.1% of tests ended with at least one advisory, a problem to watch that did not fail the test; the most common was “Tyres: slightly damaged or cracking or perishing”.
The same fault on any wheel or side counts once.

6 years of the Toyota iQ, by year of first registration, have their own page with MOT results, common faults, mileage and how many are left. Against all cars of the same age, the 2014 cars did best at their 2025 MOT (82.9% passed first time) and the 2013 cars worst (77.4%).
Registered: cars on the DVLA record at the end of the year they were first registered (these counts start in 2014, so older years show a dash). Left:
licensed or declared SORN at the end of 2025.
Both cover the United Kingdom. Pass rate: first-time passes at normal MOT tests in Great
Britain in 2025; all cars: every car first registered the same year.

How we use engine sizes.
Toyota iQ fuel economy and CO2
The Vehicle Certification Agency’s new car data lists the Toyota iQ from 2009 to 2014. On the NEDC test (listings 2009 to 2014), official combined fuel economy for its petrol versions ranges from 54.3 to 65.7 mpg, with CO2 of 99 to 120 g/km.

Official NEDC figures by engine and fuel, listed 2009 to 2014
Official figures from laboratory type-approval tests. VCA says they may not be achieved in
real-world driving, and should not be used to rank cars with similar figures.
Engine sizes are rounded to the nearest 0.1 litre. A version is one line in
VCA’s data (description, gearbox, engine and fuel), counted once however many years it was
listed.
Matched from VCA’s model names “iQ, MY2012”, “iQ”, “iQ MY2011”, “iQ, Model Year 2011”. How we use VCA’s figures.
Toyota iQ safety recalls
DVSA lists 4 safety recalls for the Toyota iQ since 1992, the first in 2010. The most recent was launched on 7 January 2015.
Risk of fire
Launched 7 January 2015DVSA recall R/2014/160
Defect
Oil may accumulate in the turbo charger and in certain circumstances flow into the combustion chamber. This may cause engine damage. In extreme cases oil can be ejected from the engine and if it comes in contact with an ignition source may result in a fire.
Remedy
Depending vehicle diagnosis modify intercooler layout to improve air flow; upgrade ECU software; upgrade turbo charger and/or vacuum pump
A recall applies to cars built on particular dates or with particular VINs, not to every Toyota iQ. The details come from manufacturers through DVSA, which says they may be delayed or
incomplete. To check a specific car, use GOV.UK’s vehicle recall check or ask the manufacturer or a
dealer. How we match recalls to models.
Figures cover Great Britain (England, Scotland and Wales). Northern Ireland is not included.
Licensed counts are vehicles with a current tax or exemption at the end of each year (or the latest quarter). SORN counts are shown separately.
First registrations count vehicles registered in Great Britain for the first time, including used imports.
Models are grouped by DVLA’s generic model name, so every generation and trim counts together.
MOT figures cover normal tests of cars aged three and over in 2025; retests are excluded. Age is rounded to the nearest year.
DVSA records the model name typed in at the test. We match those names to DVLA’s generic models, so a handful of tests may be counted under a close relative.
