I've been having a reoccurring problem that even my dealership has yet been able to fix successfully (on it's second stay at the dealership). The vehicle will lag specifically on the up shift. Revs will go up to about 3k - 4k and then there will be a 2 second pause where the vehicle bogs down before the transmission shifts. In addition to this, moving the lever over to the manual mode position does absolutely nothing. Also, the vehicle will not go into reverse and won't rev when reverse is selected. Initially the tech changed an actuator which fixed the issues for a few days but they came back. Has anyone dealt with a similar issue and been able to get it successfully repaired? The vehicle is under warrant still but it is slowly approaching the 30 days in the shop mark.
