Passenger seat belt wet?

ChopsZ

My '16 Base is having the same exact issue, on the same exact side, at about the same exact spot on the belt, and only about a foot long. Again, a LOT of heavy rain here in Florida this past week and was also driving in heavy rain yesterday on the highway. The belt has been wet for the past couple of days, but today it is completely dry.

And no, no drinks, no leaving the belt hanging out the door or other common sense stuff.

Also reset the windows even though there was nothing wrong with them to begin with.

There's no moisture inside the car anywhere.

I even went and pulled the exterior B-pillar cover to make sure the screw was installed for the roof trim from when the roof was wrapped. It was there and screwed all the way in.

So I have no idea where this water came from. My only other thought is that it came up from under the car somewhere, possibly from driving through some shallow standing water. Other than that, I'm at a total loss.

david81968, did you come to any conclusion on this issue?

Rear side window leak?

No, I don't have any new conclusions. I think your assumptions are about the same as mine. My two guesses: It came in through the small side window or came up from the deep puddles I was driving through.

It hasn't happened since. I'm hoping because it was such a HEAVY downpour, that it won't be happening again anytime soon...but it is Florida.

I have a 2016 Nismo with same exact window leaking. I have seen water stream out of the corner from the very back of the window while driving in rain. It does not leak in the automatic car washes I run through.

Any panels/parts removed for mods? Are the rubber plugs just behind the roof, under the hatch in place and in good condition? Have you removed the side roof covers to check for intrusion routes?

FYI, water intrusion on a new vehicle rarely happens while driving in the rain. Angularity is wrong and rain is shed too quickly. Even car washes are probably too brief. It is usually a small gap that only shows itself with a large volume of water over an extended period of time. My dad ran a sprinkler on his SUV for two hours then drove his new swimming pool to the dealer. Got a new vehicle out of it.

Also check for a urine smell. If you're scaring your passengers they may not want to admit to pissing themselves.
