A320 AP tried to kill me :)

Hey Guys

Hoping someone could tell me where i'm going with wrong with this. I understand their is sim issues with the AP but not very familar with the A320 (only 737).

I was on a flight KFLL to KORD and all phases of the flight were normal. I commenced the descent maually and set the alt based on the STAR. HOWEVER when getting near the approach i had the ALT set at 2000 and it completely ignored this and kept descening rapidly (not on managed alt).

I kept pressing engage selected altitude nothing, pressed engage vertical speed nothing, pressed level off aircraft nothing STILL DESCENDING.

I had to disengage the AP and climb drastically as i was only 200ft off the ground. I then lost my bearings as it was bad weather and had to disengage the AP entirely so it couldnt even help me line up with the RWY and couldnt hold an alitutude. 

Is there something i have missed or is this really the AP not working.

Also just to add to this, when it ignored my ALT i didnt have APP or LOC set yet.

The AP is currently broken, this has happened to me as well, literally sends me into a suicidal nose dive when i turn it on.

Seems to do if each flight for me when I near the approach. This flight however was the worst

You might want to check this topic.

There seem to be different AP issues, but if it's trying to drill you into the ground, reloading the plane might help.
