Not sure how this is Ford's fault. Your car was damaged so severely, that it was totaled and your insurance company paid you out. You chose to keep it and keep using it. You assumed ALL responsibility for ANYTHING happening to it at that point. It's the chance you take.
What does my accident have anything to do with bad software?
Yes, in my book, Ford absolutely shall be responsible for bad software and any known issues that have nothing to do with accident.
In fact, my accident is not bad at all. However, in California, car repair cost is so high that insurance company decided to total the car. Since then, I have solved a couple Ford problems that have nothing to do with my accident and Ford refused to take responsibility for.
1. The infamous "Stop Safely Now" error. I read Ford actually replaced entire battery pack for some owner. My fix: Disconnect high voltage cables; Clean terminals really good; Reapply ample amount conducting grease. No more issues for 14 months and counting. What does it have anything to do with my accident? None whatsoever. Everything to do with Ford program/software is too sensitive to certain sensors' readings.
2. Audio would not come on after in car phone call. My fix: Turn off HD. No more issues for 12 months and counting. What does it have anything to do with my accident? None. It has everything to do with bad Ford software that sometimes it won't be able to switch on HD audio and the system stuck in between two states.
3. 12V lead acid battery is only good for 3yrs. When it dies, no matter how much energy left in your main battery, you won't be able to open door or start the car. Stupid design.
Again, your car was damaged SO MUCH that your insurance company totaled it. Who knows what modules, components, etc were damaged. ALL bets are off. If something goes wrong, doesn't work, glitches, etc, then you have no recourse, and no one to blame.
There is no way I would EVER trust driving or riding in a salvage titled car. Who knows if the airbags will work if there is another accident, etc. You made the decision to continue to use it. There is nothing wrong with that for you personally, however Ford is 100% off the hook if anything stops working, and you chose to accept that.
