Rear taillights generally have gaps. In fact, the most fundamental reason for the gap is the problem of workmanship. If it is a new car, you can contact the 4s shop for handling. If you don't handle it, you can complain.

Bumper plastic is easy to deform after scraping, which causes the gap to become larger or smaller. It is really not easy to "reshape" and return it to its original state. You're fine. I touched the bottom of the front zero light slightly twice. At present, the gap between the bumper plastic under the headlight and the headlight is uneven, the outer side is one centimeter, and the inner side near the middle net is close to the lower edge of the headlight. I tried to press it back with my hand, but I couldn't correct it. Eliminating this correction will be a "huge project". After such memories, I came up with an idea. I hit a hole the size of a goose egg under the fog light, pushed it directly into the hole with a jack, and then pushed it out of the front wheel cover with a broom handle. The collision and the use of jack lead to uneven clearance. I'll take it down later and push it up with a jack.
