Problems with the accelerator pedal: symptoms, cost and affected models
We have documented 5 faults with the accelerator pedal in 1 engine and 4 cars, affecting 7 models of car in our database. The most important by severity and frequency: accelerator pedal slow to return on the Toyota Aygo (2010 campaign) (Toyota Aygo I), the accelerator pedal can stick fully down because of condensation (Toyota Auris I, Toyota Corolla IX and Toyota RAV4 III) and 2010 recall for the accelerator pedal (1.0 VVT-i).
How it works and why it fails
Accelerator pedal
The modern accelerator pedal is electronic: a sensor sends its position to the engine control unit. Some models have had pedals that stuck because of condensation or the design of the mechanism, and manufacturers corrected this with recalls.
What to do
If the pedal is slow to return or sticks, press the brake firmly, shift into neutral and stop the car in a safe place. Check that the floor mat is properly secured and does not interfere with the pedal, and see whether your car has had the campaign done.

- 1High severityOccasionalFrequency: OccasionalToyota Aygo IAccelerator pedal slow to return on the Toyota Aygo (2010 campaign)In January 2010, Wikipedia records a Toyota recall over the accelerator pedal, which could return slowly to idle; it covered the Aygo, 107 and C1 built between February 2005 and August 2009, although it was later clarified that it only affected the automatic Aygo.
- 2Critical severityRareFrequency: RareToyota Auris IThe accelerator pedal can stick fully down because of condensationToyota issued a recall in Europe (January 2010) on several models, including the Auris, because the accelerator pedal mechanism could accumulate condensation in cold weather and stick or return very slowly to idle, with a risk of unintended acceleration. The campaign covered Auris cars built between October 2006 and January 2010.
- 3Critical severityRareFrequency: RareToyota Corolla IXThe accelerator pedal can stick fully down because of condensationToyota issued a recall in Europe (January 2010) for several models, including the Corolla, because the accelerator pedal mechanism could build up condensation in the cold and stick or return to idle very slowly, with a risk of unintended acceleration. Gebrauchtwagenberater.de dates the affected production window between October 2006 and December 2009.
- 4Critical severityRareFrequency: RareToyota RAV4 IIIThe accelerator pedal can stick fully down because of condensationToyota recalled several models in Europe (January 2010), including the RAV4, because the accelerator pedal mechanism could build up condensation in the cold and stick or return to idle very slowly, with a risk of unintended acceleration. The sources consulted place the affected RAV4 manufacturing window between late 2005 and early 2010.
