We had our van parked on a driveway with a front facing slope, we had hard rains went we where going away there was water coming out of the seat belt on the passenger side and the panel above the window was stained down to the window support where the air bag is. I've been reading reports as far back as 2008 we have a 2020, went taken to the dealer they want 1000 to 2700 to remove the head liner and try to fine the problem, which what was reported didn't help. The dealer recommended to not park with the front of the van facing down hill if rain is forecast, my problem is that Toyota has not been required to fix the leaks. I'm calling my local dealership tomorrow about are leak.
