i'm getting my updates today. The car has had some small annoyances that don't really impact it that much. I have, however, had the stalling issue if I don't give the car a minute to warm up a day after refueling. It happened twice within 100 yards of my garage. Hoping the updates fix that and don't cause anything else. The car has been great aside from this stuff which has been minor for me. 1700 incredibly fun miles on it!In case anyone is curious about the date, April 18th 2017 was the date all new cars came with the updated engine coding from the factory.
