Justin, since the trunk is wrinkled..........
Not a good sign.

If you fear repotting, 'I'd repot,' insert a stick/stake deep inside container. If the stick comes out moist, the soil is still wet. Don't water. Wait a few days and retest.
What size and material is the container?

I don't care for self-watering pots, but some people swear by them.
Daily watering in a self-watering pot is murder.
Did your friend water the soil or down a tube?

Can you place the plant outside? Since it's so warm, the soil will dry faster.

If it was my Pachira, I'd carefully remove 'and toss' its current pot, add fresh, well-draining soil, pot up, then place in bright light.

But it's up to you, of course. Good luck, Justin...Toni

Yep, sounds rotten.
Soft trunk is pretty much the nail in the coffin.
I've never seen a soft Pachira trunk recover.

@Toni- the pot is possibly glazed ceramic with basically no drainage at all. Since my friend knows next to nothing about taking care of plants, I would guess that she watered the soil only.

@Josh- yes, my fears were confirmed today. I got the soil to mostly dry and now its leaning from side to side- almost no roots to speak of. :(

Thanks guys for your thoughts, I guess I will tell my friend to start mourning!
