No, not as of yet on mine. It seems to slide perfectly with very little effort. It is full to the max, with an assortment of 50/50 cans and soft goods, sure it is very heavy.
What exactly made you notice your problem...? Did it stop sliding in/out easy...?
I might lighten mine up now after hearing about yours.
Thanks for the heads up.
