Well it happened again. My audio went out yesterday for the 2nd time in a week. This time I can definitely say it was immediately after I disconnected my home charging plug. I returned from my errand and plugged the car into my Level 2 charger. Audio was working fine up to that point. My wife had to use the car for her errand 10 minutes after I got home. She unplugged the charger cable, started the car and presto - no audio. I have not seen any additional comments from the other thread contributors about any recurring issues after their DSP connectors were secured. So I'm going back to the dealership tomorrow and I'm going to mention the findings in this thread. However since I have lost my audio 2 times now and each time was after I removed the charging plug, once on a DC fast charger and the second from my home charger it hard for me to imagine is a loose connector. Fingers crossed.
Mine was resolved by getting a firmware update that had to be done at the Ford Dealer. Over the air was not an option for the fix. It happened a couple of times before the Dealer and Ford (Corporate) came up with the right firmware to get it resolved. The dealer initially did not have access to the right firmware to get our sound working.
Follow up/update. I brought my Mach E back to the Dealership on Monday 4/12 with hopes that another system reboot would work as it did the week prior. It did not. The service agent said they would then order another DSP unit to replace the unit currently in my vehicle. I got a call from the Dealership service agent last Friday 4/16 who said Ford has a software update which should fix the problem. I brought the Mach E to the dealership this morning and they performed the software update. The result is a functioning audio and bluetooth system once again. I hope this update sticks. The DSP unit is still on order just incase. Here's a copy of the invoice.
Tone settings reset is a known issue. They will fix it with an OTA.
UPDATE.......So much for 30 years of loyalty to a dealership which includes 6 purchases, 2 leases, countless service visits, and several referrals. The earliest appointment was in 10 days....can't believe their only MME technician is booked out that far. Service is blaming it on the holiday weekend. If my service contact wasn't off today, my answer may have been different. So I called another dealer and could have brought it in later today, but chose tomorrow instead.
Well, about 10 weeks of ownership and no sound came back, so I pulled the negative terminal off the 12V battery for several minutes. What was interesting is that this coincidentally happened the next day after I finally PaaK'd my wife's phone and created a new profile for her the night before (then deep sleep). Had not connected charger or any other actions also reported here. So far audio has since been fine the past couple of weeks, so thought I'd report here.
