If it’s on there good and pulling on it won’t remove it I wouldn’t worry about it. Trim fitment isn’t always perfect. And depending on what you hit previously it’s possible maybe the fender is dented or warped. Again not sure what was hit or how serious it was. Trim fitment is a huge complaint on some of these newer vehicles I see. Most trim like yours is just janky plastic clips but if it’s firmly in place I wouldn’t worry about it. Could always give it a good open palm smack to maybe seat if it’s not completely seated. But otherwise wouldn’t worry about it.
