My two year old Honda CR-V will not retain all of the water in the screen wash tank and it leaks out to the front near side. I am told by the Honda dealership that it is a known problem by Honda and their answer to it I am using the "wrong" water.

I am also told that Honda will not repair the problem under warranty, which I believe requires the headlamp washers/jets to be replaced.

I contacted Honda by email and although I received an auto reply have heard nothing else for three weeks. I truly think this is a safety issue as it is impossible to know how much water is in the reservoir even after you have just filled it. What should I do?
