I have Super Cruise on a 2023 GMC Sierra 1500 Denali Ultimate. The Super Cruise works, but Auto Lange Change does not work.

I am not in Haul Mode. When trying to change lanes I get the message that shows an Exclamation mark and says "Unable to change Lanes" I think this is the same message that would come up if towing something (I am not). Nothing hooked to the hitch.

The Dealer does not know the issue. So I am just waiting for now to see if a software update eventually fixes it.

I figured I would post here to see if anyone else have a similar issue?

So far mine works, changes lanes by itself, changes lanes when I activate the turn signal manually. Things I found that are just quirks, if you activate the turn signal manually and it isn't 3/4 of the way into the lane you are changing into, it changes back. I found using it in Carpool lanes will cause abrupt steering movements, especially when there is a 2 foot area between the lane markers, and an exit or entrance area has lines that are at a sharp angle, the steering will move at the same sharp angles. Construction areas where the lanes have been moved about 5', the SC wants to drive in the old lane area, not in the new one. Otherwise, so far, so good.
