I say basically new because we’ve had them for maybe a month. Had to run the dishwasher again to get it unstuck. It’s a crappy apartment provided dishwasher that doesn’t do its job well (notice the food stains that won’t come off). There’s still melted plastic on the heating element and the plastic fumes are strong.
Edit: I was never taught that you’re not supposed to put knives in the dishwasher. Going forward I will wash them by hand. Thank you all for letting me know.

I wash my knives in the dishwasher all the time. Wood handles and riveted handles suffer, but plastic handles wash just fine. Stop buying shitty knives.
They don’t, actually.
The plastic on the handle is a thermoplastic. Every time you send it through the dishwasher, it loosens a bit each time. Eventually the handle will become a danger to use with no way to fix. Before that happens, small gaps form which will harbor bacteria.
Also the water spray causes them to bounce around and dull (or in the case of the OP’s ceramic, chip)
Finally, the harsh deferent used degrades the plastic. This won’t have any issues that’ll crop up before the first two become problematic, but it will cake the plastic to turn whitish
Basically, my parents agree with you and also wonder why my knives actually stay sharp.
