WotLK Cannot use or escape vehicle in WG

[WaterInside]

In the last few WG battles I would enter a vehicle, but be unable to use the abilities or even exit it. I basically had to hope opposing faction members would destroy it for me.

When I would press "1" for example, I could see it register in the sense that the ability icon would highlight, but nothing would happen.

Any suggestions?
