If anyone is still having trouble with their vehicle, with some testing I found that after a car's reset (or re-index of USB drive via unplugging and plugging back in), the songs will not necessarily shuffle, but will more so return to an alphabetical order.
So let's say you're playing All Time Low's album "Nothing Personal". If you're playing the first track of the album ("Weightless") then turn your car off and on, once that first track ends the next song to play will be the song with the first place in the alphabet (in this case "A Party Song"), and then it will continue in alphabetical order until it goes through every song on that album.
So by adding a number at the beginning of each song's title, you can force the car even after a restart to play your album in order.
This is exclusive to the song's 'title' metadata, and changing the file name has no affect on what order the song is played after restarting your car (or playing the album in general).
I've also discovered that adding a '.m3u' (playlist) file to your album's folder has no benefit for the issue of your car restarting. By categorizing songs in playlists the car will actually completely forget what song it's playing after a restart.
I also found an oddball occurrence with some albums, where it wouldn't play in alphabetical order like I mentioned, but instead in a seemingly random order, not in actuality. When I tested "Dirt" by Alice in Chains, after playing the first song on the album ("Them Bones") and restarting the car the next song to play was "Untitled", which is not the next song in alphabetical order. I tested this specific album a couple of times, and the next song to play was always "Untitled". I encountered the same occurrence with "Phobia" by Breaking Benjamin. Regardless, using the numbering method I mentioned before fixed this issue for all the albums that had this issue.
I should mention I was testing on a 2021 Equinox. I hope if you're reading this I saved you the headache I received. If you're particularly tech savvy I recommend Mp3tag for easy title changing. If this didn't solve your issue let me know!
