How many miles do you currently have? did you notice which gear you where in when it happened? could be ten speed trans not down shifting to a lower gear when trying to accelerate
try using eco mode on highway, some report it smoothes things out with shifts, or try stepping into the pedal harder...
2021 2.7 with 600 miles and have all these same symptoms
regret buying this thing already not even going to bother going to dealer until there's a fix id rather it just blowup
