Roof leak prius prime 2024

Your usual suspects:

- Drainage for the sunroof/moonroof getting clogged
- Seals for the sunroof/moonroof going bad
- Seals for the glass roof going bad if you have that

 

I had to look up 'roof handle' since I'm obviously not cultured enough to know what those are.
In the deep South region of the USA we call those.....(*)...um.....'Oscar Sierra' handles.

Either way?
This should be a warranty issue for a 2024.

I've had to erase my last 4 comments after that, but I will try to be polite.

If you cut a large hole in your roof then you 'may' weaken that structure.
Placing a......um (*) large load on a 'roof handle' may torque the assembly in such a way as to allow for water under pressure to enter into the people compartment - like, while you're driving in the rain.
AND...yeah.
I get it.
This is usually more of an American thing - since they 'grow 'em bigger' down here.

If you do not have a sun-roof then this is almost certainly a factory defect.
Even a lard-butt American yanking on the 'OS' handle while trying to haul themselves out of the cramped confines of a Prius-sized car should not cause a windshield (wind screen, in polite company) to leak.
