I have a Vitara brezza and I accidentally hit my rear bumper with a heavy bag while I was loading it in the car. There were no scratches or dents when I checked the bumper, however the gap between bumper and trunk seems to have increased. I don't have a photo clicked, however I can share a similar image down here. The bumper seems to be fitting fine from the sides though at the center it's a bit wide. Any ideas how do I fix it?
I'm going to speculate that there are some tabs along this edge that are designed to pop into some slots adjacent to them and hold this into place. When you bumped it they popped out, perhaps they were already loose due to being removed before. Perhaps they are mostly broken off. That's not uncommon.
I'd try to pop them back in. Look closely and see if you can find where the tabs are and line them up with the slots and then try to push them back in. It may take a smack with your hand or fist to get them all the way in.
If the tabs are damaged or broken you may have to look at an alternate means of fastening. Perhaps some zip ties or even some adhesive could be useful.
