Solution to front bumper corner popping out?

Was curious if anyone ever found a good solution to the front bumper and it’s tendency to pop at the corner near the headlight?

I had my bumper replaced due to someone hitting me and the replacement bumper tabs on the new bumper are very malleable on the passenger side, so every time I pop it in, it immediately pops out. The driver side is more rigid, and therefore the tabs hold into the female coupler just fine.

I was wondering if there is any way to make the plastic injection line where the tabs rest any stiffer, which should cause the tabs that rest on that protruding line to function correctly by holding in the female coupler.

Thank you

Did they use an OEM or Aftermarket bumper? Either way, I would be driving back to the shop and asking them to fix it. It should not be popping out unless you hit something. Either the bumper is bad, the tabs on the bracket are bad, or something is wrong with the fender alignment. I have 20 years experience in the body shop, it should not have been delivered if they couldn't keep the bumper snapped in.

According them, it’s an OEM bumper (which it appears to be), but there are reports of new off the lot 4r’s with the same issue. The problem from me removing it and examining the bumper, is that the injection mold is too thin On the line where they Mold the tabs. When the tabs click into the female coupler on the vehicle, any outward force (like clipping the rest of the tabs in place), causes that flimsy injection molded line to bend, which cause the tabs to lose good contact with the female coupler. If that line was firm, those tabs would be fine.

The real issue is a poorly designed bumper tab system. It’s just not robust enough to hold in that corner unless absolutely perfect.

That is exactly what I would try. You may need to clean with Alcohol prior to using the 2 sided tape. There are 2 versions of the tape out there, you want the Red backed roll with grey/black adhesive for Automotive. Oreilly and Autozone sell some small pieces, but if you go back to your shop and show them the thread, I bet they will hook you up for nothing.
