Brand new Toyota Sienna. The moonroof/sunroof keeps leaking. Been to the dealer multiple times and when we come back the adviser always tells us the van won't leak anymore only to find out the next time it rains, the car leaks again. We don't know exactly when this started happening( we guessed it leaked a long time ago due to the rusted parts around the glass) since no one really sits in the back. The dealer already replaced the glass and the rubber seals around it.
