Has a vibration in the driveline when in towing mode in 5th gear. Also really annoying having the down grade automatically downshifting.. this feature should be off unless turned on, not automatically on unless turned off. I live in mountainous country and it is just annoying. IMO the transmission shifting should be like out 2014 Camry SLE V-6.. Console shift and fully controllable by the shifting lever. I would expect a lot better from GM especially on a vehicle this expensive.
