If this is a RS trim with a spoiler on the trunk lid, that's also exactly where the tabs on the end of the spoiler leak down onto the taillights.

How-To: Fix Trunk Spoiler leaks on Gen 2 sedan

If you have a Gen 2 sedan and have a water leak in the trunk after rain, it's likely one of two things: 1. The third brake light - there's a recall for 2016/17's to replace the gasket. Sometimes after the gasket is replaced, the third brake light assembly itself will crack. This water usually...

Is this how it looks like when you removed the spoiler? I have a 2017 LT with RS package and I have the same water leak issue. I have been to dealers more than 3 times and they replaced right taillight but it still leaks

Yep those tabs are right above each taillight. They will drip down directly on the taillight housing and make it appear the seal is leaking.

Thanks a lot! I tried to seal the spoiler around the outside, as I didn't want to go over the troubles of removing light housing. I'm not sure if that'll work lol

Super easy to remove, just a foam gasket that will reseal if you clean up around the light.

The tabs themselves need a blob of silicone applied around to stop the dripping. Mine sits on an incline with the trunk facing down in the driveway, so water just pools behind the lip of the spoiler when it rains.

Thanks! Would you mind telling me what tools I need? I'm in another state and about to head out to buy tools first. I got silicone seals in my car, and just wondering what kind of screwdrivers I need

A 10mm, an extension, a swivel joint, and a trim puller tool for the rivets on the trunk got me to all of them.

This is super helpful. Thanks!
Just curious, if it's caused by the leaky spoiler, the water doesn't go to battery compartment and thus wouldn't damage the battery / electronic units, right?
