Thanks for you replies - I had read about the condensation thing on the flywheel but mine will do it after only being stood a few hours on a red hot day even if it has already been driven that morning.
I guess I just find it really odd that my partners doesn't do it but mine does...
We both have the same car the only difference being is mine is an ES and her's is an EX, same year, make, model, mileage, service history.
I would of thought if the clutch plate was somehow glazed that if Honda had taken it apart and inspected it they would notice that is more shiny/slippy that it should be, should usually be coarse. But we are assuming that the main dealer is being 100% honest about the 'works' they have carried out. Unfortunately due to other issues the car has gone back for (e.g. the air con with 'no faults' yet required £700 in repairs eventually when they found the problem that they said it couldn't possibly be) I am somewhat suspicious of anything they tell me and have lost a lot of trust in them.
Jocko - have you tried de-glazing yours or is this something you just accept and live with? or has you tired it and it didn't cure the issue?
I certainly won't be trying de-glazing it myself as the car is still under warranty so I just let Honda deal with it. I've raised the clutch issue with them several times so if it claps out under warranty or even after I suspect I have good grounds to back and get it replaced as they have told me they've inspected it and all components are in good working order!
