Espio 60V driving me nuts

I have an Espio 60V that I got(new)in June this year and it is driving me nuts.
I took it to America on holiday and used 5 rolls of film(Kodak Gold),(ASA300).
Out of every 36 shots it would mess up around 7 and the rest were ok.
Most times it would"lose"some and out of 36 I would get 20-25 the rest were blank.
I got back and used different film(Boots universal) and the same again.
Grainy shots, out of focus, missing ones, blank ones..........
now I am pretty steady with a camera and most times never shoot into the sun but this is beyond a joke.
Even when the camera was on a flat surface and did not get shaken and on self timer it still messed up shots.
Anyone got any thoughts on this?
