Well, starting to think than mine was the only one affected by the update.

Hi everyone. I’m new here and looking for some direction. I have a 2024 Sierra 2500 Denali which I love. Last weekend it had an over the air update (Saturday). Since then I noticed a couple of things but yesterday had an actual issue. 1. immediately after the update, the adaptive cruise started spontaneously disengaging. Not a big issue, just kept driving and turned it back on later. I figured a sensor got dirty because I was on a long trip. 2. The truck has started idling oddly. It has always been rock solid at idle, now it is continuously changing by a couple hundred rpm’s while idling. It’s not rough at all, just changing. 3. Yesterday while driving home (again with the adaptive cruise control on) we came to a stop in traffic. The adaptive cruise did its job and the truck stopped as normal. Then all of a sudden it started accelerating hard while the car in front was still stopped. I hit the brakes and all is well, but that’s an issue. I’ve put on some miles and the truck is over 40,000 so I’m out of factory warranty and under the extended warranty that I got, but I don’t think I should have to pay for the copay for the extended warranty when it only started after a Gm update. has anybody else seen these problems? thanks Matt
