This happened to me today for the first time. 2019 GT with 37k miles. Last night when I plugged it in it wasn't a perfect fit, you can kind of tell when you really get it right, or if you don't. Last night I remember that I didn't get it perfect. It still charged just fine, so this morning I had the "check engine" and the ---'s for the battery and gas/batt mileage. I keep my bluetooth OBD2 scanner with me, so I picked up the P1AF7 powertrain fault. Remembering my 'bad' connection last night and reading thru the forum, I just reset the fault codes and continued on my way to work. So everything's normal as of now, we'll see what happens tonight when I charge it. I have an older ClipperCreek charger a friend gave me after he upgraded, the cord is pretty beat up so i'll look into that as well. -tony
