I have a 2013 Volt with 36K miles and just this week the USB connection for the stereo stopped working. Oddly enough, it worked fine for the last few weeks but stopped this week when i tried a different USB cable. Now, it syncs up and plays audio from my phone for 20 seconds and then loses the connection. I have tried other cords but nothing seems to make it work consistently. The good news is that the Bluetooth is still working.

Anybody have any thoughts?

Debugging the USB connection

...Anybody have any thoughts?

Isolating the cause of such problems can be difficult. Suggest putting some mp3 files on a flash drive and plugging that into the USB socket in the center console while the radio is off. Check the manual for max size of the drive and max number of files that can be in the root directory. When you turn the radio on select the USB source and then give the system several minutes to index the flash drive before selecting a song to play. If that works then it is not the USB jack in the Volt that has failed. You can then turn off the radio and connect that same flash drive via one or your cables. Then turn on the radio and it should again work. You can then try going back to your original cable, the one that worked, and/or try a different phone. Make only one change at time so that you can identify the change that causes things to work or to not work. You can also search the forum for similar problems and/or look at the list of similar threads at the bottom of this page for similar problems and how they were solved. Good luck.

Huge clue there.

Take a flashlight and see if there are any dust bunnies in the USB plug. In fact if you have an iPhone, the lightning port quite often gets crud inside. As more dust gets in the hole, the lightning plug pushes it in and squeezes it against the end of the outlet. I have had it get so bad that the plug doesn't "click" in. The solution was to take a toothpick and pick the crud out.
