Hey Dal - How did you get in touch with Ford for this? I work at a dealership and they even tried to update mine via USB two days in a row and failed both times. Multiple errors reported, and I'm not sure what else to do. Still stuck on 3.5.4 from Dec 10. Did you ever get your update?My mannequin is not getting OTA updates. I know it was not driven much at the dealership. Ford Pass App says 3.5.5 is available. For the last 10 days I’ve been driving it every day and charging every night so I’m pretty sure the 12v battery is charged. I called Ford and they are going to push the update out because they show the 12v battery was low when it first tried at the dealership. Now comes the interesting part, the person I was speaking with went through my truck set up to make sure I had everything set up properly, which it was. Until she said the parking brake has to be engaged for the update to go through. I questioned her on the parking brake and she said she was reading it off her computer screen. I had never heard this before and wonder if it’s something new.
