Welcome to the Canon Forums and thanks for your post!
This is unusual behavior as the camera should stop zooming when you release the zoom rocker. This community is designed for your fellow Canon owners to help each other out with any problems they may encounter. We do hope someone is able to assist!

It sounds like there may be something going on with the internal zoom switch or maybe the remote port. It may be a good idea to use a flashlight to look inside the remote port in case any debris is causing a false connection. Otherwise, it would probably be best to have the camera checked out at a service facility.
Hi thanks, on research this is a reoccuring issue with the XA line. The rocker switch on top of the body of the camera has a transducer that is not in a sealed housing, and it developes problems. I run a fabrication clean room and fixed it. For folks who have this problem, a can of compressed air might let you blow out the switch and fix it. If this does not fix it, consider a reomote zoom control switch. They cost between $60 and $200. Alternatively, you can (carefully) take off 3 body panels, then you can liff off the switch housing and clean it.
Hi on researching I found out the line has an issue where they did not put the switch transducer (the sensor) in a sealed housing. (I run a nano-fabrication clean room). Try this. Used compressed air (a can with the small plastic tube to aim the air) into the switch to blow out dust. Alternatively, use a remote zoom switch (they cost between $60 and $200). Finally, if you are very careful, you can take off 3 body panels and clean the switch from the bottom. Hope this helps.
