So, I was out riding Saturday and I had to stop on an incline. I put it in park, opened the door, and just as I was about to step out, clunk,clunk, clunk, it starts rolling backwards and making a horrible skipping sound…so I turned it more sideways on the hill and it seemed to hold fine…
I checked the adjustment of the cable, seems to be good. So my question is, internal damage? Anyone else have this issue? Anything else I can check before letting the dealer check it out? My warranty will cover this right?

Thanks in advance.
