Same thing happened to me......first piece of advice.......don't put coins in it!
I just worked mine a little bit back and forth. It bought me enough room to remove some of the offending coins. Then drive it a bit, and repeat the process. At times I got a little agressive with it, to the point that I figured it would just break, suprisingly, it didn't.
As a final step.......DON'T PUT COINS IN THE ASHTRAY!!!!!!
