My pixel 5 just stopped turning on one day about 2 years in, and my pixel 7 pro had the volume and power buttons fall out about 3 weeks in (not due to a drop, after googling it's apparently a very widely seen issue).
The service with iFixit was unhelpful, they told me "We keep seeing this and Google says this is wear and tear. We can't submit it for a warranty repair, and if we try we end up eating the cost". After finally complaining on twitter I was contacted by some support person who said to give iFixit this email and they would fix it. They still refused, and after a few more rounds of interactions like that I eventually bought some replacement buttons on Amazon, popped them in, and put a case that covers them on it. I'm fully expecting this to randomly die some time before 2 years is up.
Combine that with Google's extremely strong tendency to abandon everything, promises like these seem well, worthless.
Meanwhile my daughter is using my wife's old iPhone from 8 years ago. My Samsung note 3 and my s8 still boot up and work just fine (though I cracked the screen on one about 5 years ago). It's just so obvious that these phones are very low priority to Google, while other companies base their business around their phones.
My Pixel 3 stopped working because Google fucked up it's kernel boot and mechanical design. They placed a laser focus IC, that's a bare die mounted on a tiny FR4 shim to get it closer to the backpanel, on top of the main PCB. When this tiny laser focus IC inevitably breaks off or loses contact with the pads due to mechanical forces on the back panel, the Pixel 3 linux kernel ends up panicking during boot because the driver can't communicate with it.
I could see this because I had the bootloader unlocked before it bricked and could get the boot logs coming out. In fact it could boot into recovery just fine too but what a PITA to fix this at that point.
