I am new to the form because I just got my 2020 ST. It only had 3419 miles on it when it arrived from out of state last week. I only got to drive it 4 miles to the gas station and back. It started overheating so bad the over temperature screen came on. No Check Engine Light though. I spoke with the used car dealer I purchased it from and he said he drove it for a couple of hundred miles without any problems.. I had it towed into the dealer, thank you Roadside Assistance. They said the thermostat was locked shut. After that they found that the radiator wasn't flowing properly and they are replacing it. The service writer said that Ford was going to want it back to see why it's not flowing properly because it's so low miles. I do like the ST with the little bit I was able to drive it. The question I have is has anyone experienced something like this with their ST? Thx
