Is your car a 2018 or 2019? I was lead to believe that the PCM update only applies to 2018 cars and that 2019 cars left the factory with what is now the most up to date PCM. Thanks for replying!Make sure they updated the PCM to the latest update. I had all of the issues you have (except the sudden downshift) and the PCM update fixed them all. It's been 3 months so far so good (knock on wood). To my knowledge they didn't even do the adaptive re-learning procedure.
