After reading all of the horror stories on here about the leaky racetrack lights, the numerous repairs/replacements, and many out of warranty, I applied a thin bead of the Clear GE Silicone 2 product on the top and sides of the wife's new 2021 a few months ago. About $7.50 from Home Depot. So far, so good! Until reading this...

My wife is also not the most coordinated, so hoping the backup camera will help there, but... it'd be just like her to smack something into the light while loading/unloading. For those interested, I found the properties (below) of the GE product well suited in case you want to pre-emptively seal it, or fix a crack after the fact. If that doesn't work, out comes the DRILL!
