Johne,
Good question. I am still a new owner (just bought my 2020 XC40 this past May). One of the reasons I bought the XC40 was that it would fit inside of my garage. I think I have experienced what you are describing. When I first came home and pulled into my garage, I attempted to pull all the way in like I had with my previous car and the sensors picked up on objects at at the front of the garage and slammed on the brakes. I knew the items were there and have been there. I always knew how to slowly approach it and stop my vehicle within a few inches. This assured me of having plenty of room in the back for the garage door to come down and close without damaging my vehicle. I was not able to do that with the Volvo and had to rearrange a few things in the front of the garage to allow me to get closer. I assume there is something we can turn off to disable that front sensors when we do not want them on. Same as disabling the auto start/stop and folding in the sideview mirrors, etc. Will follow this topic to see if someone else figures this out. I solved the problem by cleaning up the garage, but can now see that it might be a problem in some other area where I don't have the option of removing things in the way. I wonder how this impacts parallel parking? I have not yet had to do that, but in many cases, it is a tight fit to get in a parallel parking spot, and you can easily be right up on the other vehicle in front or in the rear's bumper.
