Pictures always help!
And you really need to tell us where you are located. The fact that your maple put out new leaves "a few months ago" sounds like you are somewhere in the southern hemisphere? Here in the north, they would probably just be leafing out now.
So how late are you in your season, spring, summer, fall?
At my previous house, I had a gorgeous Japanese maple tree, not bonsai, full sized. In the spring, it would put out beautiful, perfect, dramatically colored leaves. But over the course of the season, they get sunburned or attacked in various ways. By mid-summer-ish they would be faded and get spotty. It's a natural aging process. By fall, the tree is going to lose those leaves anyway. The following spring there will be beautiful new ones again.
Don't know if this is what you are talking about. But if you give us pictures and location, you can get a better answer.
