I had a three year lease on a 2017 C Max Energi that ended at the beginning of Covid, and I turned it in. My wife loved the car and I have located a 2013 with very low mileage (33K) that I'm considering. I'm reading about the tranny issues. Should I be overly concerned, or pass because of it. I have the CarFax and it doesn't look like a replacement has been done? Thanks for any input.
