Toyota iQ (2008 - 2014)
Last updated 30 January 2017
Euro NCAP, which has developed a new rating scheme which focuses on the vehicle’s overall protection performance. The new rating scheme uses a weighted score, combining all aspects of a car’s safety performance: adult (50%), child (20%) and pedestrian (20%) protection assessment results with the availability of driver assistance devices (10%). A minimum score of 70% overall is necessary to achieve a 5-star rating. To qualify for inclusion, the devices must be fitted, as standard across 85% of the EU 27 2009 model range. Despite its compact dimensions, the Toyota iQ achieved a remarkable overall weighted score of 79%. Every iQ features as standard, nine airbags – including a world-first, rear window curtain shield airbag, Anti-lock Brakes (ABS), Electronic Brakeforce Distribution (EBD), Vehicle Stability Control (VSC) and Traction Control.
Very close runner up to European Car of the Year 2010 with 337 votes to the VW Polo's 347 votes, despite not a single Japanese on the voting panel.

What to watch out for
Reader criticism of the 1.33 IQ3 with 6-speed box, which echoes criticism of the Yaris with this engine and transmission: "The six gear box on the IQ3 is such that one is forever changing gear and having to change down for the slightest up slope on a motorway and on a slightly steeper slope even down to 3rd gear. The car will just not perform unless one keeps the revs above 3,500RPM and needless to say the fuel consumption then increases dramatically."
16-3-2012: Original 2008 1.0 manual had same engine clutch and transmission as Aygo, 107 and C1, so suffers the same clutch problems and will probably need a new one after 3 years. Toyota may put its hand up and fit this FoC. IQ 1.0 manuals fitted with bigger 190mm clutch from January 2009.
11-10-2012: Can have an EGR problem. More information here on the Toyota iQ forum (See 27-6-2014 below.)
22-1-2014: Synchro between 3rd and 4th failed on a 33,400 mile 2009 Aygo 1.0 base model. Quoted £800 to repair, mostly labour. Same fault as noticed on 107,000 kilometre Vios 1.5 rental car in Thailand. Still driveable.
15-5-2014: Severe vibrations from 4 year old IQ betqween 1,600 and 2,500rpm. Despite a total of 14 weeks with 3 different Toyota dealers, they remained unresolved. Work included new EGR and manifold (made it worse), new gearbox, balancing shafts, a drivetrain strip down and rebuild, an interior strip out and rebuild, new exhaust and cat, new wheels and tyres, and yet the car got progressively worse, though still giving mid 50s mpg around town.
27-6-2014: 2009 Toyota iQ suffering from a loss of power and struggles with fairly normal hills and slip roads onto motorways, etc. The Toyota dealer identified that it is suffering from a fault which was identified in 2010/2011 relating to a pipe for the exhaust gas recirculation system (EGR) which can get clogged with soot. There is a Toyota Technical Service Bulletin published in August 2011 that identifies the problem and provides a solution (a redesigned exhaust manifold and exhaust pipe which has the EGR pipe after the catalytic converter), which had been incorporated into new cars from June 2010. Reader quoted £1,600 to have the new parts fitted to my car. Goodwill from Toyota sought.
30-5-2015: 28,500 mile IQ bought new in October 2009 sufferend failure of synchromesh between 2nd and 3rd gear despite full Toyota service history. Initially quoted £2,700 to repair, reduced after goodwill from Toyota to £1,300. See 22-1-2014.
23-8-2016: Report of paint peeling on 2009 Toyota IQ.
30-1-2017: Report of loose rattling sound from 2009 Toyota iQ 1.0 Multidrive. Noticed when the car was started and driven away from cold. Seemed to reduce when the car was warmed up, but not completely disappear. Local garage investigated and diagnosed a worn/stretched A/C pump drive belt, which they replaced. However, although this seemed to improve the problem a bit, it didn't eliminate it. And the rattle seems to be slowly worsening. Owner wonders if the woven steel CVT drive belt might be a bit stretched and 'flappy'. Might also be the timing chain or the waterpump.
29-1-2010 Sticking Accelerator Pedal recall announced on iQ (Nov 2008 – Nov 2009). Customers who experience the problem should phone 0800 1388 744.
4-11-2010 Toyota GB announced it would recall a number of its iQ models in the UK to carry out a modification to the software used to manage the vehicle’s Electric Power Steering (EPS) system. It is working with the Vehicle and Operator Services Agency (VOSA) to contact registered owners and keepers by letter to advise them of the procedure for taking their vehicle to an authorised Toyota repairer for the necessary repair work to be done. The issue affects certain iQ vehicles, produced between 11 September 2008 and 22 October 2010. When driving on certain roadside safety side strips or 'rumble strips', signals received by the EPS sensors may be incorrectly interpreted by the EPS control unit, triggering the EPS warning light. Should this happen, the driver would need to apply extra effort to steer the vehicle. This issue has only been observed in very specific circumstances in Japan. No cases have been reported in Europe. No accidents related to this issue have been reported. The repair involves the update or replacement of the EPS control unit software. The job will take approximately two hours to complete, at no cost to the customer. Approximately 12,000 UK registered vehicles are affected by this recall. Toyota will ensure that vehicles produced before 22 October 2010, but not yet delivered to customers, will be checked and the necessary repair undertaken before delivery.
