    Today I received a letter from Toyota USA notifying me that there is a support program in place for "certain 2018 model year Prius c vehicles."

    The gist of it is that the taillight housings may develop small cracks at the lowermost, innermost corners, and these cracks may allow water intrusion.

    If this happens within 10 years of the date of first use of the car, Toyota will cover the cost of installing new taillight housings. It also says they may reimburse owners who have spent money on this problem already.

    Our car has no problem yet, just sharing the details of the letter for others.

    Thank you for sharing, my 2012 Prius C have already cracks on the tail lights, but they are internal for now. Since i'm from Puerto Rico i don't know if the support program works here.

    Hmmm...."certain 2018 model year Prius c vehicles."

    Ha! I've read about this issue for models going back to 2012, including mine which I've already replaced (the taillights, not the car).

    Yeah I don't know how they're doing this- maybe different program codes for different model years?

    Probably worth calling your dealer in reference to this one, offer up your VIN and see if there's a similar program for yours. They might buy your receipts?

    Parts like that are frequently outsourced. It's a relatively common problem overall- one of the few problems we ever had with the old Hyundai was... water intrusion through a molded lamp assembly. Come to think of it my old Subaru also had an illuminated aquarium on the back for years without impeding performance.

    Wouldn't be shocked if all those lamps came out of the same plastic molding factory.

    I like that Toyota is covering at least some remedies here. The leak on the Hyundai cost me over $100 to fix and they never did anything for me.

    that's all i've read about since joining up here, 16 years of water in the tail lights. i've never had it in any of the 30-40 cars i've owned, including 8 toyota's.

    it's always nice when a mfg covers defects after warranty, but is not always the case

    And I've never seen it in the 20 or so cars I've owned over the years. Until it happened in this one.

    My 2012 Prius C tail-light (passanger side) filled with water 4 or 5 years ago.
    Last summer I replaced with OEM. $75 each

    Now I see that Toyota is running a Customer Support Program Water in taillights. Might worth a phone call to Toyota...

    Just called Toyota about water accumulating in my 2012 C Two tail lights. They said there's no active customer support program for them, and recommended I take it to a dealership to diagnose. Yeah right.
    I'm gonna try sealing the inside edge with clear silicone caulk like in this video: 2013 Prius C backup light full of water 2 - YouTube
    If that doesn't work, I'll seal all around.
    If that doesn't work, I'll just drill a hole in the bottom.

    Update: In mid-July I sealed the tail lights (top and most of the way down each side) with clear caulk. The leak seems to have been fixed, for now at least. If it happens again, I'll inspect the seal for holes and re-patch it.
