OK - not trying to stir the pot here, but let's say I can get comfortable with the proposed fix. I have a couple honest questions for those with the requisite knowledge and experience.........because I haven't been in there to actually see the construction/assembly.
Is it possible that with the shimming that the gap between the bumper and fender could cause other issues down the road?
Possibility of the bumper cover now rubbing the fender and a potential to lead to noise or paint rub?
Too much stress on the bumper bracket?
Due to tightness, any future bumper cover removal necessitating replacement because a tab(s) will likely be torn when tugged out?

What they're doing is bonding the 1mm thick zip to the top bumper retainer to act as the lower lip, and the glue a ridge on the underside of the bumper as the upper lip. There's already clips on the bumper retainer and a lip/material to grab onto on the bumper itself.
They also added two drops of panel bond on top of the Ziptie for insurance, which I don't believe would prevent the bumper from being removed.
This purely mechanical connection is what will provide the extra support needed to keep the bumper on place, in theory. We'll find out as people get the fix.

^^ Thanks for the more "easy to understand" explanation of the TSB's objective....This helps me visualize it a bit better now

Well, that’s quite some jank… haven’t gotten my car yet snd now I am paranoid. Any home solutions invented to fix this problem without having to remove the whole bumper and have zip ties glued to it?
Having not owning my car yet, how hard is it to pull off the retaining clips and doing something like this at home?

It’ll be cool:
1. The issue doesn’t affect all 500s.
2. If it does happen, it’s gradual. By that time we will know how well the TSB has held up.
3. There have been NO reports of the bumper falling off, it’s just a cosmetic eyesore.
Get your car, be amazed by its amazingness, and drive the live’n fk out of it! 😎
::chuckling:: Because you’re an old guard and have had a front row seat to this madness. Two years of reading possible causes, to Lexus not acknowledging the issue, to finally getting the TSB….we’ve been through the wringer! (Not to mention the simultaneous gasket and fuel pump issues!) 💪🏽😎
To the soon-to-be owners, the car is rock solid and finally we have a fix for all 3 major issues.
Get the car and have fun! These issues are but a blip in the road to thousands and thousands of Smiles Per Miles and long term ownership satisfaction.

Awesome - I will be anxious to see here how it went so keep us posted - I know you have a good "in" with the dealer (lol) but I know that your info will help put a lot of us at ease...if you can have them take some pics as they go along, that would be great but I know its hard to do for them

That would be great, I know you are going to be busy and would never want to have you be neglecting your day job but you have a unique "inside scoop" that few of us have and this will help all of us see the LSB in its glory
