Window-3rd brake light leak in rain

Hi
I’m new today
I have a 2016 Tundra SR5 with 140K and in good condition, but has started to leak water at the back window above the rear seat.
Not sure where it’s coming from?
Rear window? 3rd brake light?
Thank you

 

Not uncommon for the brake light to leak. Remove, reseal and replace.

 

Any info on how to repair/replace?

 

You can find all sorts of info by using the search feature in upper right here on tundras. Use it just like an internet search.

Culprit is usually the 3rd brake light.

 

Same thing happened on my 2016 Tacoma. Dealer said there was a bad batch of gaskets for the brake light out of the factory during 16 that essentially dry rotted out. Toyota replaced at no charge due to known issue.

 

OP, with the Tacomas around the same year, the brake light seal replacement is a recall item. They replaced with a thicker gasket. Could be that there’s a recall on the tundras as well.
