Is there an issue with the 2013, 2014 moonroof leaking?
Some may leak but I doubt if it is all of them just like any other brand. Why do you ask ?
I have replaced several sunroof seals on 2013 to 2015 Toyota/Lexus vehicle because of wind noise, they leak and whistle.
The sunroof seal is not intended to be water proof however, water that may drip past the seal drips into the trough below the sunroof opening, then down the drain tubes. If there is debris blocking the water from draining that is a maintenance issue that applies to all vehicles/ vehicle owners.
