I would also prefer not to have it, however it seems like it shouldn't be leaking after 2500 miles and 2 months of ownership. I'll take it to the dealer and see what they suggest.
Did you ever figure out this issue? I took my 2018 TRD off road through a car wash yesterday and felt water drip on my arm. I could also feel a decent amount of water near the back of the sunroof.
