I have had my 2019 Titan SV into the dealer twice now to find the source of the wet carpet on the front passenger's side under the floor mat. They ran the A/C for hours, hosed down the front and side passenger doors, nothing leaking. It took an engineer from the factory stopping by the dealer to find the source, a bent rear glass frame from the factory. The way the channeling is run, water was running down from the back window frame into the framing that runs under the right rear and front passenger door thresholds. Water was traveling from the back to the right front carpet whenever it rained. No other carpet was getting wet. Have a new frame and carpet being replaced this week. Posting this in hopes if will give other owners information to pass on to the dealers if they have a similar leak on their new trucks and to avoid days at the dealer without finding the issue.
