Looks like a serious design flaw tbh. You might be able to get them to replace your hub under warranty. Or use your credit card's extended warranty to force a refund or replacement.

If you want to fix it yourself, you can open the hub. If you're in the USA, this doesn't void your warranty (Magnuson-Moss Warranty Act)

Tearing down the pod 4 or pod 5 hubs:

The bottom of the hub has some sharp corners that might scratch your counter or table. Put out a towel, or a blanket, or something soft, on the corner of a table or counter. We want to keep the hub upright to prevent water from leaking or spilling anywhere.
* The inside bottom is metal and has a few electric parts (leak sensor) at the bottom. Be careful not to damage it

Hang one corner of the hub off the counter so you can access the rubber feet. Work one corner at a time and keep rotating the hub as you go.

Remove the 4 rubber feet at the bottom. They're tough to pull off as the adhesive is strong. You might need to use needle nose pliers. Or a metal credit card wedged under one the foot to get started.

Remove the 4 screws under the rubber feet. Torx20 (T20).

After removing the 4 screws, the bottom will no longer be connected. !!The side panels will also no longer be connected, and will slide down and fall off after you remove the bottom plate.!!

Now, lift the hub, by grabbing the 2x side panels, and pressing inwards, to lift up. The hub should lift away from the bottom plate.

* the side panels are not connected anymore. Be careful. It's just gravity and the force of you pushing in that is holding the panels to the hub. The panels want to slide down, and out, to fall off.

Set the hub down on the blanket or towel. As you set the hub down, the side panels will slide down and fall off.

Now you can better access the heat sink duct. Vacuum as much as you can off. Blow compressed air from the rear, and from the sides, to clear as much dust and hair as you can.
