2025 CT5-V Blackwing, Drift, 6MT
256GB card holds about 2 months of driving for me.

I have the "auto overwrite" feature turned on.

But when the card is full, it will not overwrite the existing files and stops recording.

Is this a 2025 bug?
 
I have the same issue. I have to go into the PDR and disable and reenable this toggle to get it to start overwriting. Now I'm just in the habit of always looking for the red dot when I start driving.
 
If you do not want to worry about it as often, I can confirm a 1TB card works. Mine has not filled up yet enough to encounter the bug.

Edit: Note I have a 2025. May be different for 22-24.

My ‘23 4BW manual says to use a FAT32, Class 10 required, 8, 16, 32 GB. I put a 32 GB in and so far so good over 2500 miles.
