My 2021 Yukon Denali has done a few 'automatic braking' episodes at 60-70mph with everything I can turn off, turned off. The manual says it can occur but has no info on user control - so I presume that's on purpose.
Each time, it's been a false positive while I was towing a 5500lb trailer (we mostly use the rig to toe). To me, it's at the threshold of being dangerous rather than helpful. It has occurred twice on a 2-way highway when the oncoming vehicles get a little close to the center-line at 60-70mph speeds coming towards me at 65mph. These were multi-second significant slowdowns.... from 65mph to 50mph'ish.... very aggressive, enough to worry me about trailer instability / scared me thinking the rig was going to shut down. It also occurred on an interstate at 65mph passing a truck / going round a slight right-turn in fast lane with construction barriers along the left edge of the road - e.g. sort of boxed in. It did 3 aggressive jerks over several hundred feet of the turn - enough that someone tailgating might get to close. Again, I worry about jerking the trailer behind me on a corner at 65mph.
I really don't like that this 'uncommanded breaking' software trend (not ready for real-life) and don't like that it's not under my control.
