Abysmal rumble intensity

Is anyone else's Deck not rumbling much at all? When it comes to things like using the trackpads, the haptics work as expected for me. But in terms of game rumble, it feels like the haptics motors are dying or something. They rumble ever-so-slightly. Nearly imperceptible. For instance, a game like Hades. When using an external controller, every time I attack, I get a healthy controller rumble. But when playing on the Deck itself, I can really only feel it if I have a finger on one of the touchpads (which is directly over the motors). And even then, it is weaker than what I experience when using the trackpad as a mouse in desktop mode or something. I have tried multiple games, and get the same pitiful rumble in each.

What really confuses me is that I just got a new Deck via RMA, and the rumble experience is exactly the same. Any ideas? Anyone else experience the same?
