I had the same issue

Electrical connection.

My check coolant light appeared so I checked the level to notice I was a bit low. So i went to my dealer and purchased Volvo coolant fluid. Filled it up and about five minutes later the coolant was low again. That happened twice. I made it home and checked to see if I was leaking any fluid but there...

Do the locks just keep trying to go up and down.

I have a similar issue but it is due to my rear hatch lock.
