Truck is scheduled to be in for service for a couple of days to deal with a u-connect problem, so I went out to unload some of the junk I don't want to disappear. Found an inch of water in the storage well directly under the seat on aft passenger side. The floor is soaked as well as the upper and lower sections of the seat. Truck is 2 months old - I am not happy! Since it's going to the dealer in the morning and it's going to rain all night, I didn't attempt to remove any water.

BTW: I do have the sliding rear window.

Most likely the CHMSL or the back window. If it is out all night in the rain I would duct tape over the CHMSL and see if more water comes in. If not it's the CHMSL, more water it's the window. You will do a better diagnosis than the dealer will.
 
Well at least the duck looks happy…SORRY I could;t resist… Sag is right, though, either rear window or brake light.
 
Took the truck to the dealer this morning. They seemed well aware of the problem - leaking water from the 3 brake light. They said that a felt type gasket is used rather than a rubber type and they have seen the problem many times. The service manager even had it happen to his own truck.

Truck will be at dealer for at least 2 days. They say it takes 2 days to diagnose a water leak and it also takes 2 days to diagnose the u-connect problem it has. Hope they can overlap the work!

I will keep you updated.
BTW: We've had 5" of rain so far this month and more is coming.
 
Just had a call from RAM service. It was the 3rd brake light leaking. They will keep the truck another day to get it as dry as possible. This works for me since I park it outside and there is much more rain coming.

I would suggest that all new RAM owners go ahead and silicone the 3rd brake light. I know this has been a problem at least as far back as the 2nd gen trucks. You would think that something this simple would of been fixed years ago.

Yes that should have been corrected by now. My 18 year old second gen leaked also. I better check under the seats of the new truck.
 
Yuma gets 3.36" per year. Portland had that much in a day a few days ago. SNOKING

?....... And the ducks on the lot?
As far as I know, nothing, Service guy said the leak doesn't start until the truck has at least 5,000 miles on it. Mine had 2,000 miles.

The day after my truck back I discovered some damp/wet areas, so I've been running a small heater plus a fan in hopes of preventing future problems.

Sorry, but I might have missed it.
Did you replaced the gasket ?
If so was it the same gasket or a rubber one ? Part number ?
And did they pull carpeting and check for rust/damage ?
 
My understanding is that the fix involves putting silicone on the gasket and reinstalling. Not sure if a new gasket is involved, but I can see the silicone they used. Hard to get a straight answer from the service writers.

They did not pull back the carpet. I've been running a heater and a fan for a couple of days and that has it dry everywhere I can check. I do believe that the proper way to do this repair would be to pull the carpet and seats and then dry everything and reinstall. I'll have the truck in Arizona and SoCal for a month this winter and the 10% humidity will finish the drying job.
 
You can also put in a dehumidifier in the truck if you have one available and run it for 24 hours or more. I have used this approach on another vehicle quite successfully. I have a unit in the basement that I use from time to time to keep the relative humidity down when needed.
 
The "carpet" under the seats does not really absorb water like the carpet on the floor of the truck. Water can get under it though.
