Lirio93

This happened to me briefly about a year ago, but went away if its own accord. yesterday had the coolant system replaced and now its doing it upon acceleration. I sound like a hot rod. I’m hesitant to take it back to the mechanic if it’s just an electronic noise cancellation system problem.

My 2017 CMax has been at the dealers for two weeks trying to get the new modem to connect to FordPass. They say that Ford engineers are “aware of the problem and looking for solutions.”
