On my *2018* LS 1.5L 6 Speed with 27k miles I am getting a hesitation/jerking at the 1-2 shiftpoint. Sometimes this is just a short jerk/shudder, and other times it is up to a full second before power returns upon 2nd gear engaging. I also am getting what feels like slight slippage shudder at WOT at higher speeds. Also, and this is more rare, on long trips when going 50-60 mph, I get a very slight power surge lasting 1-2 seconds every 1-2 seconds (similar to what it would feel like to tow a trailer, which I have never done with this car). Before I take it in, is anyone else having these issues with the 1.5L 6-Speed LS or LT? Thanks!
