I occasionally find my right foot slips off the accelarator pedal, especially at the wrong moment. For instance when pulling away at a junction when you need that extra umpff !  Has anyone else experienced this ?

I can't say that I have - I have no issues with my pedals - I assume yours are like mine?

Is that an OEM carpet mat ?

Seems to be the wrong colour for an OEM mat as it does not match your trim colour.

 

I respectfully suggest you get a rubber mat as the slippage is probably your heel sliding on the carpet; or just remove that matting.

 

Or are you wearing leather soled shoes !

 

Be safe.

I'd better take a picture of mine tomorrow. I have the Alphard carpet that came in the vehicle, matching the trim colour. My pedals are the same as yours Paul

Yep, a picture might help, and I'm not fussed about my carpets - they fit well and don't move around.
