Trans heat exchanger

I have a 2020 berkshire Forest river 39A
I noticed at 3000 miles I was losing coolant...
The low level light came on.
I topped it off and crawled under the coach I noticed this metal Box was leaking from the 2 hoses on either side at the clamps so I tighten it.
When I checked the next day I noticed it now coming from the weld joints....see pics..
Could this be a manufacturer defect only has 3000 miles on it.

Welcome to iRV2

Sorry your first post is about problems .

Yes ; it's a part manufacturing defect , the part was installed by the chassis manufacturer , so that's who to contact about warranty replacement.

From the photo, it's hard to tell if the leaking fluid is coming from the welds. It could still be pushing out past the hoses and leaking. Your hoses are using the spring loaded hoses clamps. I found that in really cold weather, mine started to leak and I had to tighten them quite a bit.

I was hoping that was the case also.
The clamps are standard, tighten with flathead screwdriver.
I wiped it clean and it's actually coming from the round weld spots.
Unbelievable for sure...

Those do look like cold /poorly penetrated welds. That would be poor for liquid tight item. Seems like if it was tested from manufacturer the leaks would have showed up.
