My 2018 and my 2019 have both done this. I have no MIL's though. Talked to the dealer today and he said he thinks the 2019's have a problem with the Throttle Position Sensor and he's going to check it next week. There are times when it's worse than others and I put it in Tow/Haul mode just for the relief. Several times the transmission has down shifted so hard (both 2018/2019) models I swear someone rear ended me. Or it shifts so hard I my u-joints are broken. I never had any of these problems in my 2012 or 2015. I haven't been on the Ford forums but the grass sure is looking greener on the other side. I fell off the Ford bandwagon after my 2004 6.0L fiasco. I can't bring myself to by a Dodge...The definition of "dodge" in the dictionary is "to avoid an encounter with"...
