I totally agree. Last month I was flying it for two days without the A/P. Today I'd it again and it completely screwed up again; first it changed the pre-set altitude during a descent, then it changed the speed we'd set - a couple of times. Not to mention that the F/D is flickering on and off the whole time and EFIS comp mon is coming up and is hard to get straighten out. I simply don't trust it! Someone needs to bring it in and de-bug it before something goes really bad. If you fly it before it is taken care of, pay attention and be on top of what you have pre-selected because it will change......
