Just saw this the other day. Does anyone know the part number and best place to buy it? Why the heck is there that cap anyway?

 

Tow cap. Folks have either had it fall out or stolen. You can buy (unpainted) from the dealer: https://www.mylparts.com/oem-parts/l...cap-5212930907

You might also consider the eBay painted one: https://www.ebay.com/itm/13-15-LEXUS...K/202158918150

 

yep, the tow hook provision hole is under there.
the actual tow hook is in the trunk and you have to install in into the hole when being towed.

if I recall correctly, the cap should have a tether on it....if not, it should have lexus designers!

 

You can buy a painted one from Japan for $5 plus about $5 shipping. I made a thread on this:

"Anyways an unpainted one from the lexus dealer in the USA is $20, but you can buy a painted one from Japan for $5:

Scroll down the page the part numbers start with 52129 and they accept paypal, just submit an inquiry with the correct part number. and they get back to you in about a day with the payment link.
Shipping is fast only takes 2-3 days from Japan.
