Well, my 2020 ST was in and out of the dealer for a third time this year for the smoking issue and they didn't do anything to fix it. When I talked to the service rep after almost a week, he said they tried to replicate the problem and saw heavy smoke on one day, and light smoke on others. When I started an email exchange with him, he denied saying they ever saw heavy smoke. Anyway, they let it idle for 5 hours (?) and then took the exhaust system off and couldn't find any problems which doesn't surprise me since the cause of oil leaking into the cylinders to combust would be well north of my exhaust system so I'm really confused by this diagnosis.
As of today, I emailed the service guy back and sent him two more videos of it smoking and asked to have the Service Manager call me. I also contacted Ford Customer Care line and created a "case" to have a different Ford Tech consult with the local techs and possibly travel here to look at/fix my ST. That should be a few days is what I'm told. If there is no resolution here, I'll begin the buyback process with Ford through their Reacquired Vehicle Program.
Lesson learned, record your conversations with techs and/or communicate via email so everything is documented.
Here's a video of what's happening since I got it back from the dealer. Of note, it does seem to be worse when parked in my driveway which is a slight incline with the nose uphill.
HOLY SMOKE
