First Time Toyota Owner - First Time Roof Leak

Hello all,
After 20 years of Ram and Jeep products I took a chance on a 2024 Tundra Platinum 3 weeks ago. I love all the features except the indoor water park. We had an early snow and when it melted, I had water running from the A pillar handles, the overhead console switches, and the sunglasses cubby. It looked pretty much the same as the video of the leaking 1794 that was posted on here a while back.

The dealer looked at it and couldn't find any issues so it was sent to a body shop and they stripped the headliner out, hosed the truck, and left it to sit out in a rainstorm overnight. Neither time it had any signs of water ingress. I spoke with the dealer this morning and they said for the time being, their best guess is the sunroof didn't close properly and to keep an eye on it.

I suppose at this point I'll just keep my service records documented for if/when it happens again. I just assumed that since the sun roof is mandatory on their top 4 trims that it would have been figured out by now.

Anyway, rant over, here's hoping nothing else pops up before I have to make the first payment.

 

Welcome from NY.
Hopefully it doesn't happen again.

 

Thanks, also being from NY with more snow on the way I'm hoping to not have a repeat issue.

 

So the dealer wasn't competent enough to remove the headliner themselves and had to send truck to a body shop? I wonder what's the reasoning behind this.

I recall that such leak had something to do with the sunroof drain hoses either being clogged or something wrong with connection and that led to water coming out near the vertical handle inside of the cabin.

Or maybe the seal for the sunroof wasn't installed properly...

I would imagine they would be able to see any of these common issues quickly

 

You also get that Canadian snow.

I wonder if it's the seal around the windshield if it's not the sunroof or drain line.

 

Welcome from LA (Lower Alabama)! Sorry you're off to such a start with your new truck.

 

They said the body shop was better equipped to pull the headliner.

I don't think it was from the windshield, the sunroof pan had water in it as well as the interior lip where the sun shade lands.

Worst case this is step 1 of 4 prior to arbitration.

 

"Indoor water park" <---Thats funny right there

 

2024 Tundra Splash Mountain Edition?

 

Almost sounds like this dealership doesn't have competent techs.

I pulled the headliner myself when installing camera extension wire to route to my camper. Took me half hour...

You just have to carefully yank on the headliner... I followed instructions steps and didn't find it terribly hard. And I'm a complete beginner when it comes to working on cars.

If this happens again, I would go to a different dealership

 

That is....fucking insane lol

Hoping you're able to get it fixed up soon.

 

Welcome to the new generation of Toyota engineering….

 

Check the antenna at the rear of the cab. Mine is loose but doesn’t leak. I wonder if it can get in there and run to the front of the cab due to rake and then find an exit???? Just spitballing an idea

 

Weird coincidence, I accidentally left my new Platinum's roof popped up last night, it rained during the night and I came out this morning and was amazed that is didn't let a drop inside.

 

That definitely sucks....

I'm thinking one of three scenarios:

1: Sunroof either did not close properly or was accidentally left open. Check to make sure your sunroof is closing and 'seating' properly when closed; your owner's manual should have a reset procedure for the sunroof to ensure it's operating and cycling properly.

2: Sunroof drain channels are clogged (probably not given how new it is unless pine needles or something is stuck in their). The drains are located at all four corners of the sunroof. This can be checked by taking 8' or so of weed whacker line and running it down the drain channel holes into the 1/4 panels (they empty to the front and rear quarter panels). You should also be able to pour a small amount of water in the sunroof channel and watch the water drain through to the ground. When sunroofs close, they don't really create a watertight seal, they are actually designed to allow a small amount of water into the channel which then drains out and onto the ground.

3: Top seal of the windshield is not sealed properly and allowing water in. You should be able to test this by spraying/running a large amount of water along the top and top corners of the windshield, if it's leaking here you should see the intrusion.

 

I feel like the body shop handles windows/sunroof/windshield type of issues.

 

I had this issue with my 22 1794 but only twice did this happen here in Florida while I had vehicle. Noticed both times truck was parked front end sloped slightly lower than back. Leaked from driver side grab handle.

Dealer initially checked and could not find anything. Drain lines etc the typical stuff. They tore apart headliner and determined pan for pano roof was not seated/sealed correctly and they removed and replaced. Pressure tested after replacement and got my truck back.

I don’t have truck any longer as I traded in after 1.5yrs for a 23 Pro but did not have any issues with leaks after that.

 

Hosing it for 15 minutes and leaving out in a rain storm with no headliner they couldn't find any leaks.

I'll see about the reset procedure.

 

I tried the reset procedure and everything looks the same before and after.

However, I took a gallon jug of water and some weed trimmer string out and the driver's drain works fine, the passenger side has a blockage about 5 feet down and I can't push through.

My guess is the slight slope of the parking lot at work allowed the water to pool on the passenger side until it overtopped the tray.

 

$50k lol, if only

 

Greetings from over here in Daphne!

 

I just spoke with the dealer where I purchased it and initially had it "fixed" who are 100 miles away. Their regional manager happened to be in the service area when I called and he's going to call my local dealer that is 20 miles away to have them do the repair to save me half a day's worth of driving.

I didn't purchase locally because they offered 10% less on my trade and their Platinum was a 2023 with features I didn't want vs the 2024 that I ended up with and being 1 year older it didn't price out well with my credit union's lease program.

 

I'm glad you were able to identify that... and yes depending on slope and rate of water coming in, a blocked drain can definitely allow water to get inside the truck. Basically, it spills over the channel once it fills up and ends up coming in between the metal and headliner then down into the cab. Neighbor that had clogged drains had it coming in the overhead console area and the driver's side A pillar.

Anyhow, I'm not positive, but it sounded like you were taking it to the dealer to have the clog cleared, correct???

If not, you can also try to blow it out w/an air nozzle connected to a decent air compressor. If you have someone run a little water down the cleared drain while you're positioned low, you can identify what hole, etc. the water drains out of. Then you can blow air up the channel on the clogged side to see if that loosens it, or run your trimmer wire up from the bottom. If you do this I'd just hit the clog a few bumps, then go back from the top down to see if the clog moves.

PS>>> when you shoot air from the bottom, close your sunroof so you don't blow the clog into the cab on accident; plus the it'll create a little more pressure in the tube when shooting air in.

PPS>>> Any dealer should be willing to provide your warranty service(s); does not have to be the dealer you purchased from

 

Yes, I'm taking it to another dealer that is closer.

I couldn't find the bottom of the hoses it looked like it was draining through a pinch weld.

 

I guess I never followed up. Later in November 2023 the local dealer said they found the passenger front sunroof drain and the AC condensate lines plugged and they blew them out with air. Fast forward to today, 7/31/24 and the passenger side is blocked solid in the same location based on depth of trimmer line inserted and the same downpour in the interior. I have an appointment with the local dealer again next week. The sunroof pan is absolutely spotless so I don't see how it could be debris and I generally only park the truck outside at work so I doubt it is more "insect nests" as the dealer claimed last time.

I tried a 1/8" steel coiled drain snake and compressed air neither of which made any progress. The drain snake hit the same point as the trimmer line and stopped and I couldn't get enough of a seal with the air compressor blow gun with a hose on it to do anything. The drain hole is larger in diameter than the slot that you have to pass through to access it so I'm not sure how I could make a seal to pressurize the tube.

I pulled the A pillar off the passenger side and ran my borescope down and can see the line all the way down to way it makes a right turn and seems to go inside the body. Right around there is where the depth gauges get stuck. As far as I can see from the roof pan down to that point there's no clogs or pinches. I am nearly positive the hose is kinked somewhere out of sight but can't prove it. If I could lower just the passenger corner of the sunroof and pull off the drain hose I could send my borescope down the tube to investigate.

This marks my 3rd trip in for the leaky roof in less than a year of ownership and under 6000 miles.

 

Is it possible to call the dealer and ask them how they blew the lines out?

 

I called service and described the issue and they just immediately setup an appointment. I'm going to ask to have them show me how I'm supposed to maintain this as they told me last time that leaking sunroofs aren't a warranty issue and they were "fixing" it as a courtesy since it was only a month old.

 

I bought a tiny diameter snake cam and was able to send it down the drain tube without pulling the headliner, behold, the pinched tube of calamity. I'm going to bring this and the camera to my appointment Wednesday.

 

I'm sorry to hear you're still going through this. Interestingly enough, I had to "lemon law" my original 2022 Tundra TRD Pro for a very similar issue. They never directly tied it to clogged sunroof drains on mine, but they evaluated and "fixed" it five or six times without ever getting it right. Seems insane, but at the end of my ordeal they just had to replace the whole truck with an identical 2023 model. So far so good with that one thus far. Not totally sure what the deal is with water ingress on some of these trucks. I wouldn't say the issue is "widespread", but there have certainly been some reports of issues. Panoramic sunroofs (and sunroofs in general) can be a pain with water clogging issues, but they seem particularly egregious with a few of these reports.

 

If it was clogged then fine but this is a build screw up in this case. I'm more annoyed that last time they said it had a bug nest in it and they blew it out. A nest wouldn't go through the pinch weld so that was a lie. At least say we blew through and now it drains, don't fabricate an issue that you definitely didn't troubleshoot. The dealer I bought it from had the sense to tell me they don't know what the problem is vs make up a story.

If I could get this replaced exactly except no sunroof I would.
