For those interested in the lack of emergency stopping/braking by the vehicle itself... I did some research on this because my wife complained that it was non-existent compared to her old 2019 Ford Explorer that her GCL Summit replaced, or my 2018 Honda Accord Touring that my 2021 Diesel Gladiator Rubicon replaced. Both of those vehicles (explorer and accord) had the safety packages and were very proactive in audible/visual cues when getting too close to a vehicle and both were known for braking for you in certain scenarios.
Jeep (CDJR more fully) employs a slightly different system than some other brands. In others like Ford/Lincon or Honda/Acura the system is much more proactive and regardless of slight user inputs if the system doesn't like the scenario ahead it will either beep/flash or take additional action to stop. The system we see in the Jeeps will NOT take action if the system senses ANY sort of reaction in terms of driver input. Jeep is clear about this and the reason is to try and avoid false reactions and brake slams that have cause accidents themselves. The Jeep system is designed to take action, or give you warnings when it notices NO changes to drive inputs at all with an imminent threat approaching. IE if you make a very slight decrease in gas, or let off gas but don't brake/steer, or make slight steering wheel correction it assumes you are alert and aware of the scenario and will not intervene. If the system sees a scenario coming and doesn't detect any changes to driver input it will then react at the necessary point. I have seen this system in action. In my gladiator yesterday (3" lift and 37 tires nonetheless) a motorcycle in front of me suddenly braked. I was not paying attention. My gladiator beeped/flashed and locked up the brakes, tire squeal and all. Thankfully it worked and nothing further happened. Too date that is the only time it has happened but in all other scenarios I always did something, ever so slightly in change or not so this sort of reaffirms what I read about the Jeep's difference in their system.
I'm not discounting what some of you have stated as potential problems, who knows maybe there are bugs. Just saying the system IS different than others. In my Honda I could tailgate someone actively (speed up slow down to stay close) and the system would still engage, or warn, if necessary. That is almost completely not the case with these systems though if there were a brake slam I would think the system would react as intended if I continued in that second with my driving as previously done.
Food for thought. I'm trying to find the article I read explaining the jeeps systems but so far I can't.
