We have a pair of Intel 13s at the company as a pilot test, running Ubuntu.

One of them had a battery failure: the battery swelled inside the laptop. Framework determined it was out of warranty, since it was more than a year from purchase, so we paid for the new battery. (Along with some extra excitement because the 45W supply isn't provisioned to handle peak demand without a battery, so we ended up with an Amazon-delivered 100W supply to keep it running until the battery arrived.)

The other machine occasionally hangs. We're still trying to run it down, but it looks like it might be the SSD powering down and failing to power back up.

My overall take is that I really, really want to love this product, but a work machine has to be reliable, and these laptops are falling short on that front.
