This will create a public issue which anybody can view and comment on.

Please provide as much information as possible. At least, this should include a description of your issue and steps to reproduce the problem. If possible please provide a summary of what steps or workarounds you have already tried, and any docs or articles you found (un)helpful.

Problem you have encountered:
kube-system pod in my GKE node in autopilot mode is stuck, causing my node to be not removable since 13 March 2025 and charging me a lot of money per day. this is the pod name: filestore-lock-release-controller-59c549fcdf-j9rk4

What you expected to happen:
In autopilot mode of GKE, a node that is not used by any of the customer pod but only system pod should have been auto removed after a quick while.

Steps to reproduce:
1. use autopilot GKE
2. use GKE version 1.31.6-gke.1020000
3. create a deployment with accelerator class with nvidia-tesla-t4 for the node selector with n-standard-32 type
4. remove that deployment and wait for the node to auto scale down

Other information (workarounds you have tried, documentation consulted, etc):
I have asked billing side, they are not willing to help me to escalate the issue on the first attempt.
I have submitted feedback on GCP console top right
I have tried deleting it manually but then I got:

% kubectl delete node gk3-planetgpt-nap-1of8foas-4e86bdcf-iy1u
