[Q] No vibration a week after lollipop topic

I updated to lollipop about a week ago. At that point in time everything was working fine. However randomly today the vibration function in my phone stopped working. So I can't get haptic feedback or vibration when calls come in or through normal notifications.

I'm running the international stock version of the sense rom. No root or anything.

I've so far tested the vibrator function on the phone via the *#*#3424 number and it didn't work at all.

Did a factory reset and the same result.

Is there any workaround to this or would I need to root and install a new ROM?
