I went into my local Ford dealer parts dept and he was able to determine that a new 4G modem could be ordered. Cost was around $330. I then spoke with the service dept who told me that my car is not covered for the installation. My car is a 2015 C-Max Energi SEL. So I called Ford and got no where with them. I ended up sending a snail mail letter to the name at the top of the Bulletin. No answer yet. Has anyone had the 4G modem work done on a 2015 or 2016 C-Max? Thanks.
