I've owned my 2012 FFE since the summer of 2013. Overall, I've been happy with the car, but like many others I've experienced a few Stop Safety Now incidents along the way. All so far have been fairly minor, mostly happening in my garage at start-up and easily reset by restarting the car a couple times.
That was, until yesterday. On my drive home yesterday I experienced my first SSN while driving, lost power and coasted to the shoulder of the road. Unfortunately, the SSN message wouldn't go away using the reset produdures provide by Ford in one of their recall lettes (power-off, restart after 2 minutes). I also tried the power-off, open door, restart but nothing would work. I tried for about an hour and a half while waiting for the tow truck and the 12 volt battery finally went dead before the truck arrived (obviously no power was making it out of the high voltage battery to the 12 volt battery).
The tow truck tried to boost the 12 volt battery to hopefully drive it on the truck, but as soon as it was turned on, it threw a SSN warning and wouldn't move. Unfortunately, I've not had good experiences with the dealer it was towed to and don't have much confidence in their ability or willingness to solve the problem without completely emptying my wallet in the process (my last and final visit to this particular dealer was when they they tried to charge me an hour's labor to measure my tire tread depth to evaluate for warranty replacement).
I'm wondering what symptoms others have experienced before a high voltage battery failure, and if anyone has tips on typical diagonistic codes I should be aware of or TSBs I can refer the dealer to etc. I've already been told to expect a fee just to diagnose, which I honestly feel should be covered under the battery/electric components 8-year warranty. Ford has had enough documented SSN problems that they should be providing free diagnostic without question.
I'm located in Canada so any experiences form fellow Canadians would be especially appreciated, but all any and all advice is appreciated.
