Any suggestions on whom to call at Ford. I purchased it used in July 2019 with 15K miles o[/color]n it. I had the radiator fluid changed at 40,000 miles in the beginning of October. I may have put 400 miles on it. She's a 2019 SHO, I have had everything changed early. Oil at 5k, PTU at 10k and the diff at 20 and 40k. This all started a week or two ago and I had the radiator fluid changed a month ago. Any advice would be welcome. The SHO has done mainly highway miles till COVID.... Help
