4 DVSA recalls for the Toyota Iq
Most cover a batch of cars built in a set period, and dealers fix them free. Sweep’s check shows the recalls for a car’s age and whether the DVSA has one outstanding.
Risk of fire
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.
Fix: Depending vehicle diagnosis modify intercooler layout to improve air flow; upgrade ECU software; upgrade turbo charger and/or vacuum pump

Braking efficiency could be reduced
Due to possible contamination within a brake pipe on right-hand drive vehicles foreign material can potential enter the brake master cylinder and cause damage to the brake seals. This can result in a reduction of braking efficiency and increased brake travel.
Fix: Recall all affected vehicles where the brake master cylinder and offending brake pipe will be replaced.

Electric power steering sensor may malfunction
If the vehicle is driven over/on certain types of roadside safety side strips (Rumble Strips) it is possible that the Electric Power Steering (EPS) control unit could incorrectly interpret the signal from the sensor. This could result in the need for the driver to apply extra effort into steering the vehicle under some driving conditions.
Fix: Recall all affected vehicles and either reprogramme the EPS control unit or the replacement of the steering column and control unit.

Accelerator pedal may fail to return to idle
It has been identified that on affected vehicles condensation resulting from cold-weather use of the heater or other causes may form on the worn surface of a component within the throttle pedal assembly known as the friction device. If this occurs there is a possibility that in the worst case the accelerator pedal may return slowly or does not return to the engine idle position.
Fix: Recalled vehicles will have a precision-cut steel reinforcing bar fitted into the accelerator pedal assembly which will create a space in order to reduce the surface tension between the friction device and a component referred to as the pedal arm. The subject bar also strengthens the reaction force of the spring that returns the accelerator pedal to it's non-pressed position.
