I got a letter from Ford yesterday regarding my 2016 C-MAX Energi, about program 17B28 which involves replacing the throttle body.  That sounds like significant surgery. 


It says "On your vehicle, the electronic throttle body may develop contamination.  This may result in the vehicle entering a protective low-speed mode accompanied by illumination of the service engine soon indicator..." It goes on to give more details about the low speed mode.  Then it says that I need to have the work performed by 9/30/18 in order to qualify, the repair takes half a day, that the dealer repair time may vary, and to go schedule that appointment.


I searched this forum for 17B28, throttle body replacement, and a few other possibilities and did not see any mention of this bulletin.  I'm guessing it's either too recent, or perhaps it involves too few vehicles to be mentioned here yet.


Replacing the throttle body sounds like substantial surgery.  Considering that replacing the air filter takes a page and a half of instructions, this is what I suspect.  Has anyone had this done?  The impression I have is that this won't be a "sit in the waiting area" experience.


Lastly, if anyone has more detail about this flaw and how it develops, I'd really like to know more.


Thanks much!

Replacing the cabin and engine air filters on the cmax is excessive and a bit ridiculous, but relatively easy.  Throttle body shouldn't be too big a chore for your dealer, but likely tedious and depends on how good their wifi and snacks are as to whether or not you should wait.  If a loaner is available, I'd opt for that! 


Good luck and let us know how it goes.  Wonder if the 2017s will be affected!
