V90 flooding in rear cargo area

So day five with my new to me 2018 V90 R-Design. We had our first rain today. After the rain I went out to grab something from the rear cargo area and noticed my daughter’s backpack was soaking wet. I felt the carpet, it’s wet. Side panels, wet. Roof, wet. It’s wet in both sides. Lift up the spare tire cover and the spare tire area is full of about an inch of water. I started thinking clogged drain hose but seems like that would be random for both sides to block at the same time. Then I remembered a question I asked the sales guy when I purchased it. To me, the gasket surrounding the sunroom had a weird gap on both sides. He assured me that was how the water drains, but the gap is big and is unlike anything I’ve had on my other cars with a sunroof. It’s about a quarter of an inch long and located about 7/8 of the way towards the back of the sunroof. Against my better judgment I trusted the salesman since the Volvo had been regularly serviced at this dealer’s Volvo location.
Would anyone here be able to confirm whether this gap is supposed to be there or if I’m missing some sort of plug on each side?

Seems to be a pretty common issue with the sunroofs on these cars. The gasket shrinks and that gap opens up. Then you get water intrusion. More than a few threads on this.
Don't know if you are still covered under CPO coverage or not, but it's still a pretty weak move on the part of the salesguy.

This is the part I believe you need:


Not too expensive. Even if it was CPO I am not too sure if that would give me much confidence. Many times they will fight with you on the warranty anyways. That's how a lot of them are I guess. 🤷‍♂️ I found it kind of annoying. I think you should be ok though. They are very reliable cars overall.

I think you are right on the part.

I checked the front water drains and they appear to be working. Will have to wait until I’m done drying the back with a box fan to get it on a slope to see if rear drains are clogged. I imagine the big gaps in my gasket allowed so much water in at once that even one clogged drain could create an issue. I’d say the temporary solution is to park downhill but there are a bunch of horror story thread about leaking from the windshield into the sensus unit (and I’m in Florida so hills are hard to come by).

Thanks for the help everyone

The more I read here the more I appreciate my dealer, Lehman Volvo in York, PA. When my car was in for a minor software issue I showed a 1/2 inch gap on one side only to the service manager and simply asked if this was a known issue. When I picked the car up a few hours later the gasket had been replaced under the 4/50 warranty.

This is a known issue, there should be no gap, I believe this has been mentioned in a couple of TJs as well. Basically, they need to replace the seal and glue the ends to the sunroof panel. Not a horrible job to DIY if you are out of warranty, only need to pull off an interior trim piece and then take off a couple screws to remove the glass panels, you don't need to drop the headliner.

I have a 2020 model and it has the same gap, went through a half hour of driving rain but have not noticed any water intrusion. Does the strip have to have come unglued as well? Have you noticed whether or not the ends are snug or loose? In any case I intend to get it replaced asap.....but should I put some duct tape over it until then?

I am not sure the gasket gap and water intrusion are related.

Although there are multiple cases of gasket gaps on the forum I don't recall them being related to trunk or passenger area water intrusion.

Based on other SPA threads:
( 1 ) The gap in the seal should be as small as possible to reduce the chance of debris clogging the drainage path
( 2 ) The presence of the gap itself is not cause for water intrusion into the cabin. If a joint in the drainage path somewhere behind the interior trim is disconnected, you could run into this issue. @OP, is the water intrusion more prevalent on one side of the vehicle?

Yep that's why I said the go is not causing the water in the back.

The gap can increase chances of clog but without a clog it shouldn't matter if there is a gap or not.

I would investigate way more the drain than the seal!

I have rather large gaps on both sides. 2021 V90. Have been through some rough downpours and also just steady slow rain. Both driving and sitting in the parking lot at work. Never had any water get in the car. I also pressure wash at home every Saturday...even if it is raining. I think something else might be going on with the OP's? Maybe something got in the gaps and clogged the channel?

At my first scheduled maintenence I mentioned it to the service writer and he shrugged it off. First time at the dealership for any service in the past 15 years and this along with him grinding his shoe into the door sill in a twisting motion while carrying on a conversation with me about how many miles were on the car... I quickly remembered why I do my own maintenance. That and the $100 tire rotation fee that I did not opt in on. That's pure gold.

For reference, the car is originally from Colorado, spent 1 year there, came with the gaps, and has been here in South Texas for the past year. Yes, it does rain here. And when it does it is a "gulleywasher."

Regardless...I got sick of looking at the gaps and covered them with 3M Super 88 Black electrical tape (even, gasp, Wal-Mart carries it) cut to 1/8" over the exact width (pushed the 1/8th into the channel) and 1/4" over the length to overlap the seal and end piece. The Super 88 is thicker than the regular stuff and I don't even notice the gaps anymore.
