No its a very old problem indeed and has to do with the air under the sucker
the changing air pressure outsieide and the different expansion rates of
glass and plastic.
I doubt there is any good solution unless you want to glue them down.

I have a Dashcam on the windscreen and a SatNav on a smooth
plastic plate on the dashboard.

Both are held in place by suckers, as is usual.

However, they both have a tendency, particularly in hot
weather, it seems to me, to lose their 'suck' and fall off at
inopertune moments.

I was wondering if some kind of grease or oil on the sucker,
instead of the usual saliva, would provide a permanent
(ideally) solution or, at least, a longer life than at
present.

Any ideas?
