I haven't heard of it and my understanding is that the Miyota movement is very reliable.
I found this thread on another forum about a Miyota 9015 with similiar issues. See post #8 for some troubleshooting steps, but the thread is woth a read.

Edit
After rereading your post and the thread I linked to, they seem to be discimiliar issues, but possibly still worth a look.
