So, after doing the Android Auto update, I lost the Pandora app from the home screen. Turned out that was normal.

So...I went to using a USB drive for listening to music and maintaining playlist. 90% of the time it works as expected, but occasionally on startup, or once or twice during playback, it just loses the USB drive. I either have to unplug, replug the drive, or move to a different source and move back.

Anyone else see this? It is possible that it is my drive, but I don't want to replace it if I don't have to.

I only had to remove the drive and replace it ONCE to read the drive again. Normally it just boots up with the rest of the cars electronics.
I thought I read somewhere in the manual that you should take the drive out when you shut down the car or the drive could not work again. I don't take mine out but I keep the files on a back up drive - Just In Case. I also have about 10 play lists, one for each Genere of music/books that are on the drive in directories. I think the added folders and playlists does tax the music system. Also if you have a bad play list, you will see all kind of crazy things happen to the system. If the system acts strange, pull the USB drive and restart the car. It may take care of the problem.

I use KINGSTON DTSE9 thumb drives in the car right now. Have had very good luck with them. If you have a low priced drive you need to be careful as they sometimes mis read or down right fail.
Just my thoughts.

I have a USB drive plugged in all the time. Occasionally it will not be recognized at startup and only an unplug, replug will bring it back. I have never seen it disappear during playback. It may be a bug in the startup sequence, but it doesn't happen often enough to troubleshoot.

What size and type of drive do you use? There are numerous threads about forum members having issues with different types drives. Is it a micro thumb drive, regular thumb drive, small external usb hard drive (4"x3"x0.5"), etc. I've read about people plugging in small external usb hard drives that had some issues because of the size/capacity of the drive (e.g. 1 TB).

In general, usb thumb drives can be put in place and left there forever. In my case, I have a 32gb Sandisk micro thumb drive (usb 2.0) in my G2 volt for 16 months and maybe had one freeze in all that time. I've also read about some USB 3.0 micro drives overheating and starting to have issues. But if that is the case, then then it may be difficult to nail down because of the intermittent nature of your issue.

If you provide a little more info on the type and size of drive, then people may be able to better help you with your issue.

Side Note: Have you noticed any issues with being able to charge your phone on the USB ports. If so, then there may be more going on there then just reading the drive. There is a thread about USB ports not functioning correctly but that may not be the case.

The drive is a USB 3 32 GB Sandisk. I am 99% sure I formatted it with FAT32.

It sounds like this is a known problem, as a lot of people have the same issue.

I love the Volt, but this seems like basic functionality to me. I will probably report it to the Infotainment system people so they can look into it.

Ok, so it is the USB 3.0. Was it HOT when you pulled it out and swapped it to the other USB spot. If so, then it may be a sandisk drive issue and not a volt issue. If it is not hot, then you can test the drive by doing a stress test on the drive with your computer but that may be more trouble than your looking to get into.

Hopefully, this issue doesn't pop up too often so you can simply enjoy your volt and music. Good luck. ;)

My 2016 (Gen2) Volt has major reliability problems with an iPod plugged into the Volt's USB port. It will be playing along and then suddenly, usually between tunes, Volt will "lose" the iPod, displaying a message "media not available" or something along those lines. At that point nothing can be done, short of unplugging and replugging the iPod, and often even that fails to regain recognition of it. Sometimes I will get that "unavailable" message right after starting the car, in which case I will do that trip without the option of music. Next time I start the car, the iPod may or may not be recognized. IOW, It's all a crap-shoot from one trip to the next.

I have had my new Bolt lose the USB on startup a few times, then it will not access it until I pull the stick and re-insert it. It might be faulty sticks, or it might be faulty connections, not sure at this point.

Same here, since first month of owning car...dealer only says they "are looking into it" but that the ports may just be overloaded.
