MaxwellHammer Posted October 21, 2013 Report Share Posted October 21, 2013 I have a 2013 SEL (with all the perks except park assist) that I took delivery of in late May. Have just loved the car and had no complaints. I recently moved (2 weeks ago) so between selling a house, buying a house in my new location and moving, I postponed having the updates done. Last Friday I started my car as usual but noticed I had no radio ... looked at screen and it said Sirius Updating 0%. Figured it would update and that would be it. This message lasted all morning and I realized I had no audio, no voice commands, no sound when reading my texts. Drove to Ford dealer ... they could not figure out what was going on. Service person told me I should delete all facebook, google, icons etc. in contacts on my phone as this tends to overwhelm the Ford Sync system. I made an appointment for Oct. 28th for updates ... this was first day they would have a loaner available and they would need my car for the whole day. Figured I could live without audio until then as car was driving fine. Went home and deleted contacts as directed to no effect. Well, this morning (Sunday) I get up, go to car and it is stone dead ... I mean dead ... no lit screens and nothing happened when I pushed start. Called Ford Roadside Assistance. Someone came in a half hour, put jumper cables on and car came immediately to life ... sound and all. I had my audio back with Sirius and voice commands working fine! I know there have been a lot of battery problems with the C-Max's but am wondering if this Sirius updating thing and dead battery are related somehow in my case. Don't know whether I should take car over to Ford tomorrow or just wait until the 28th and hope dead battery issue doesn't reoccur. Guess if it doesn't start tomorrow decision will be made for me .... input and/or advice greatly appreciated :-) Quote Link to comment Share on other sites More sharing options...
fotomoto Posted October 21, 2013 Report Share Posted October 21, 2013 (edited) It sounds like the MFT system was in a fault loop and thus wouldn't let the car completely shut down. A hard reset via the eventual and unfortunate battery drain got everything going again. If it were me, I'd wait till the 28th.

ScooterS Posted October 21, 2013 Report Share Posted October 21, 2013 Very, very strange. I had exactly the same problem. I lost my car audio on Thursday. Friday I made an appointment to take it in today (Monday). On Sunday I tried to start the car and it was DRT (Dead Right There). I put it on the charger and brought it back to life. I am taking it in today. I wonder if it is a coincidence or some strange loop with an update. Quote Link to comment Share on other sites More sharing options...
ScooterS Posted October 22, 2013 Report Share Posted October 22, 2013 Car taken in today for multiple upgrades. Should have it back in a few days. Quote Link to comment Share on other sites More sharing options...
MaxwellHammer Posted October 23, 2013 Author Report Share Posted October 23, 2013 Thanks for the feedback. So far car has been working OK since jump on Sunday. If this continues, will take my car in as planned on Oct. 28th for updates. Will let you know what my dealer has to say. ScooterS ... sounds like you and I had the exact same problem. Fotomoto .. your theory sounds right as I am down 2 full mpg's on my lifetime average so it does appear that car wasn't complete shut down from Friday until it died at some point between Sat. night and Sun. morning.

different drummer Posted February 20, 2016 Report Share Posted February 20, 2016 I know this is a dead thread, but this happened to me *exactly*, several days ago. Sirius update 0%, unable to use any radio functions, but got home fine, and shut off car. Tried to start two days later, and dead dead dead. Will be jumping it shortly, but wondered if original poster MaxwellHammer had any more problems? Quote Link to comment Share on other sites More sharing options...
roknrod Posted August 28, 2018 Report Share Posted August 28, 2018 Same thing happened to me this week. Local repair place ran diagnostics after I mentioned the same Sirius issue. They could not detect any battery drain but it might be a good time to get rid of the SiriusXM account. Quote Link to comment Share on other sites More sharing options...
ptjones Posted August 28, 2018 Report Share Posted August 28, 2018 I don't think it is a good idea to shut off the car until update is finished. Paul Quote Link to comment Share on other sites More sharing options...
