Yeah, sounds like mine... except I was lucky, it went straight into a wall, instead of sideways, so I just broke all the bumper screws. I bought a failsafe and it's rad... I run it till it's out of range all the time, and it just stops until I walk closer to it. I don't worry about fresh batteries, just take some with you when you run it.
However, I shattered my front bulkheads and a arms, bent hinge pins, and broke shock caps when I let a friend drive it... I remember asking him to avoid the lamp post... A failsafe is not a solution to clumsy friends. Good luck! My aluminum bulkheads and RPM a arms are working beutifully. Just looking for some Titanium hinge pins now.... anyone?
