2026 Water sound in dashboard

[Joeyeyes1975]

Just picked up a 2026 Equinox Mid Night edition on Wednesday 5/6/26. Drove the car home happy as can be. The next day and to this day afits parked in garage over night when I pull out and for a few turns I’m hearing water swishing around in the dash board. Seems to be only days I run the ac. Anyone else have this problem or have any idea what it could be. I’m thinking the ac drain line might be crimped. Thanks

What did your dealer say about this?

I’m bringing it in this Friday. But you know how dealers are! Just want an idea in my head, and wanted to see if anyone had same problem.

AC drain plugged up.

That’s what I’m thinking or it got kinked during assembly.

Yep most likely your A/C isn't draining. I have had this issue once or twice in the past but never to the point of having sloshing water inside the dash. Check your carpets because when I pulled away quickly or pulled away while heading up hill I got water inside the car. The dealership should know exactly what this is right away. Also that standing water will start smelling like mildew after a while so you need to handle it.

Thanks. Luckily no water on carpet. And I know that smell have had it in other cars it’s terrible. Thanks for the reply.

I had a fairly new S10 truck with a water leak and the carpet was dry. My wife could smell it so the dealer pulled back the carpet and found the pad soaked.
They replaced it under warranty and were able to fix the leak.

What was resolved?

What was resolved?

Negative. They checked A/C lines draining properly. They also checked the drain lines on the outside of the wind shield those also draining. Ran air last couple days haven’t heard the noise. Going to wash the car tomorrow. Keep you posted if I hear it after that.
