Issue with Speed Limit Signs

Hello all, I’ve had this issue with my 23 Y. The speed limit detection seems to work for a random amount of time and then quits. It seems to randomly turn back on and start working correctly, but it’s never the same. I can drive the same road multiples times and it’s random of when it stops working. This makes it especially frustrating for FSD because I have to disengage (not going 50 in a 35). It seems to happen most often when switching between 45 and 55. The car maps the speed signs correctly, even if it doesn’t change. Is this something common or should I put in a service request?
Thank you in advance!
