Just returned from the Dealer to have my 2 recalls fixed and have them solve an inoperable modem. MFM has not worked in my car since May 2017, I was too
buzy lazy to return it to the dealer to look at the matter. MFM does not connect with the car and get a confirmation, the app just sits there awaiting forever.
So tech adviser runs diagnostics and sees a Code U0198 stored in the APIM. Suggested fix is found in SSM 47198 which is basically a reset of the modem and then reprogramming the TCU to the highest calibration. Charged me $100 under my Extended Service Plan for the deductible. Car is a 2014 Energi, modem replaced in January 2017. Modem worked till May 2, 2017 when all communications with MFM stopped.
Any thoughts? Has this happened to anyone else, or did I get ripped off of the deductible by a limited experience tech?
Thanks in advance
