Seeing the post on leaking sunroof and all the people affected I'd like to hear from people with no issues? We have a XSE AWD with Tech coming in November here in Nova Scotia. I'm a little worried about this leaking sunroof possibility as we get a lot of rain here and I do park on a slanted driveway.

Is it a rare issue or do most have this problem?

Thanks in advance.

I have the problem and I've heard a quite a few more complaints... I wouldn't suggest trying to inspect it while your driving, but just sit in it during the rain or carwash and you'll see it... I don't know about any other year, but it appears the problem is mainly with the 2021 model... There are video's on YouTube...

The Dealer had the gull to suggest that it's made this way... Try that with someone else, huh?

My sunroof leaked, dealer said it's not normal and wasnt able to replicate with pressure washer and bucket. Sent me on my way, but said that they logged the issue with a Toyota engineer. If enough people have the issue, then they'll issue a recall.
Mine looked like the drip tray was overwhelmed and leaked due to being parked on a canted street. That's the only thing we could think of.. but still, i live in socal, so if it rained like Seattle, my car would be always dripping...

21 XSE Plus. While it is usually parked in the garage, it has gone through at least two high pressure car washes plus whatever my local dealer did with the oil change. No leaks. I did take a look at the design when others starting reporting an issue, and two possibilities came to mind - 1. A defective seal or 2. Clogged drain holes. If you look at it, there are channels for the water to flow through to drain holes. I suspect in a dusty environment, they could get clogged up, causing the water to overflow out of the channels.

No issues with mine. I've had it over a year now in Florida and have been through car washes multiple times. I park mine outside, so it gets rained on often.

Parked next to it is a used 2015 Avalon hybrid with a sunroof. No leaks either.

I will be paying close attention because I noticed that both vehicles get leaves trapped in the hood and openings along the opening around the trunk or lift gate. I actually take a leaf blower to them before going to the car wash because the leaves accumulate in there.

Hope that doesn't happen in the drainage of both sunroofs.

For anyone who had leaks, was dealership able to fix it, or does it still leak?

I took ours in immediately. They could not replicate with 6 trips through the car wash and a hose running over the top. I asked if they could try it on an incline which they will do tomorrow.

they did not find any sign of permanent water damage to the liner but I am pretty upset given this is a brand new vehicle. The dealership guys have been good to deal with though.

Does it leak with rain as well? Hhow are you dealing with any permanent damage to the interior?

Mine leaks into the drip tray. I just can't fathom a manufacturer designs (as per my dealership) a sunroof that intentionally leaks into a drip tray. Can anyone think of another manufacturer and/or make that is designed this way?

Mine is behaving exactly the same, I'm very concerned the flow rate that goes into the drip tray.

Here's my remedy until there's a better fix:

I’ve been through the automated car wash several times and have never had a leak from the sunroof or anywhere else. Just be sure to turn off all the sensors before you do this though! (I wish they had a car wash mode to automatically turn them all off then back on again when done. Instead I have to go through the menu for a few minutes to disable everything.)

I just got sprayed going through car wash. Water was in the tray and the sun shade was a bit damp

The drain tubes may be clogged. Start first by clearing the drain entry holes in the gasket around the perimeter of the tray. If the water comes in faster than it can drain, leaks at sunshade happen next. Often is as simple as some sort or gravel blocking the holes

Second generation: The roof tray has a drain tube, and there is one on each side. Different colored hoses ( Maybe they got the colors mixed up, and on the wrong side? 😂 ). The hose is soft so cramming something like a stiff wire to clear it might be a mistake. I have slightly rerouted the location of my drain tube.

First picture shows beginning and most of route. Second shows tray to hose detail. Last picture shows exit tube that goes to drain to the outside.
































Where do the rear tubes go out to? I need to clean them from the bottom as mine seems clogged. My rear sunroof rails collect water when it rains and it leaks into the cabin when I start driving. 2020 limited.
