I had this recall done last week and now my Edge is throwing codes, the next morning my car threw a traction control error and my dash lit up and the traction control dis-engaged twice after this update. The first time I slid across the parking lot because it freaked out. I now as of yesterday have a wrench light saying "
Powertrain Fault
Illuminates when the system has detected a powertrain or an all-wheel drive fault. Contact an authorized dealer as soon as possible."
I took it back to ford and they could not pull any codes until it was started, They now get a P166A code, For restraint module. They say this code is saying there is a fault in my fuel pump circuit...ok.
I don't see how this isn't related to the update, but they don't think it is. If they updated the PCM and now my PCM is freaking out starting the following day, I would say that's related. They could not clear the light but I disconnected the battery for 5 min and its gone, for now...
I also see other vehicles with recent PCM updates doing similar things as mine
I would say hold off on this update unless you need it. Let them figure out the bugs first. Also as a side note, this recall is not listed on transport Canada recall list or even on Fords website with a vin search or model search. Yet I got the letter and they did the update. I have a 3.5L V6 Edge - 2016.
