Hey guys,
Been looking for a GT350 for a long time, finally pulled the trigger on a 2020 car in black. 7k miles, tech pack, beautiful car. Picked the car up on 9/16 from a Ford dealership. My first Ford, and my first Mustang.
Started driving home on some back roads, initially the car was driving great. Eventually got on the interstate and noticed a weird missing/skipping sensation at constant cruising throttle. Cruise control wouldn't stay set, and after about an hour a little wrench popped up saying "check manual". All temps were normal, I pulled over and checked the oil, new and fresh and at the normal level.
Pulled in to a Ford dealership near where I was, service was closed but the manager took a look. After I turned the car off the wrench disappeared so he couldn't figure anything out. No code was stored.
Continued driving the car home. Always restarted with no code, ran fine for a bit, and then got weirder with the missing/skipping/stutter at cruising speed the longer I drove. Car felt good in 1-4 accelerating, but then started acting up in 5th and 6th. Almost felt like the clutch was slipping, a weird miss then surge.
Got home, woke up the next morning and took the car to my local Ford dealership - not where I bought it - for them to see what was going on. Of course, on restart no code was stored, wrench was gone. Puttering around town, car felt normal.
The dealership took a week to do anything. Then, when they looked they found no stored codes but noticed misfires while driving the car. They spent yesterday on the phone with Ford, then I got the word yesterday that they found very low compression in cyl. 5. Dealership is thinking the car will need an engine replacement. They are trying to figure out how such a serious problem didn't throw any sort of code or cause a limp mode. There are more diagnostics being run before Ford approves the replacement. There are apparently also some issues with the variable charging from the alternator so they're looking at that too. Ford seems to think the alternator can cause funky codes, but I don't see how it would cause low compression... to me low compressions = engine replacement but Ford wants more proof. I asked the dealership for compression/ leakdown documentation.
Just putting this story out there so anyone who starts having similar issues can see. Will keep this updated. I'm supposed to be speaking with both the dealership service manager and a Ford rep later. Definitely concerned about the immediate loss of value from the engine replacement, and how quickly an extremely minor problem turned into tens of thousands of dollars of work. We will see what happens.
