I have the new 2024 NX350h Premier. Really enjoying this car. But when I got home after taking delivery I checked the washer fluid and it was down quite a bit. I figured it was something they missed. I filled it two days ago and looked at it today--it's not filled now. It dropped quite a bit in two days without any usage. I know there are cars that don't allow full fills in the washer container but I can't find anything in the owner's manual. Is this normal or do I likely have a leak? What have others experienced when filling washer fluid?

Thanks.

 

Sounds like a leak to me. Is there any puddling underneath the washer tank on the floor/ground? The dealer can pressure check those tanks I believe. They have a device they can put on it and pump it up with a few pounds of air and see where it leaks from. Puddling is the best way to tell without pressure checking.

 

There's a cover under the engine bay that prevents any fluid from getting to the ground. I didn't see any sign of leaking to the floor but it has to be somewhere before evaporating. I'm calling service today to see what they think.

 

I have a 23 450H+. Nothing leaking in mine except for the AC tube after I pull into the garage from running it here in Florida. But you are correct, they put covers under this whole car. Changing the oil is a pain due to having to remove the cover to drain oil and change filter. Good luck.

EDIT: The covers are a great place for critters to hide in as well. Especially squirrels.
