I have a few questions.
You state that you bought the car new. New as in 3 miles on it, new as in a few hundred, or what?
Exactly how many miles on this vehicle?
Is it known for a card-carrying fact that any of the seals are actually leaking? Can water actually be seen to run past the seals when it’s raining?
You state this vehicle is for your dogs too. How many dogs, how big, and is there a possibility this could be caused by dog urine?
It’s difficult for me to comprehend a new (as in 3 miles new) Honda being this leak prone from so many areas unless there’s a story behind it.
I would add that if the car is out of warranty then leaks due to seal fitment, door/glass adjustments, or body flex are not a warrantable issue.
