Hello, my new compass with just less than 200 miles is showing this. I took it back to the dealer but they could not find any code and asked me to bring it over when the message is active. I just want to check if anyone has seen this message. I looked online and the only place I could find it being asked is in a jeep JL wrangler forum and they have Jeep care specialists that took their information since there's a good amount reporting about it with their new jeeps.
Stop Safely. Vehicle will shut off soon. Compass Trailhawk

Unable to get any answers from dealership or anyone else. However, I think I figure it out. It appears there’s nothing special about the battery on the vehicle and should be replaced every two-three years just like any other car. All these errors are caused because there isn’t enough power for these systems to function properly, e.g. parking brake, 4x4 system etc. I replaced the both batteries haven’t had any issues.

The 2nd gen Compass does not use lead acid batteries. They use an AGM battery. Its more of a deep cycle battery. (Absorbent Glass Mat (AGM) Car Battery | Autobatteries.com | Clarios)

@JeepCares I am also having this same problem....two times now. Going back to the dealership AGAIN. The car literally shut off and stranded my daughter and we had to have it towed.

Wanted to add some additional context to this as I have also had a very similar problem and I didn't see the root cause discussed in these replies. So for anyone who may come across this via a Google search, hope this helps.
While I can't speak to why this happened so quickly to the OP, I also have a 2018 Compass and it has the ESS system, I bought it used in 2020. Initially I had a problem that was related to the battery where the ESS shut the engine off at a stop light, and when it started the car again I had a warning that the ESS system needed service and I noticed that my battery was not being charged while driving. Eventually it did die at a stop sign two blocks from my house, we were able to get it jumped and it ran fine after that, acted like it never had an issue. I took it to the dealer and they replaced the ESS battery under the (3 year) warranty.
About a year after that I had another issue. Again ESS had turned the engine off at a stoplight but when it went to start again the whole dash lit up with every warning light and individual system failure message you can think of. I was able to get it limped into a nearby parking lot where I let it sit for a while. After about 20 minutes I was able to start it with none of those warnings present at all, again the car was acting like nothing was wrong. Took it to the dealer and they replaced my main battery, which makes sense as since it's a 2018 and I'm pretty sure that battery had never been replaced previously it had been in the car since it was built in 2017.
I believe I was able to figure out more about the ESS system thanks to other posts on this forum, but I can't remember who made the posts or where they are. I'll add links to this reply if I can find them. The ESS system in the Compass has two batteries, both are AGM as @Eugene@2018 mentioned. The ESS battery is responsible for running the accessories while the car is off, and your main battery is used to start the car again. There's a "smart relay" that switches between the two and has some other special sauce to make sure the batteries are capable of running the system.
Based on my experiences, it seems that if your ESS battery has failed/is failing, the system switches back to the main battery but might not do what it needs to in order to have that battery get charged by the alternator. It's possible that it disconnects the alternator from this circuit on purpose as a safety feature. I believe the best course of action for this if it's the first occurrence or an isolated incident is to park, turn the car off, wait for a minute or two, and then start it again. See if the ESS service message shows up and disable the ESS using the button by the shifter. Keep an eye on it for a few days and if you see the ESS service message again (I often see it after remote starting the car for some reason, even when nothing is otherwise wrong with it) take it to get serviced.
If your main battery is failing or otherwise near the end of its service life, you may experience the more "dramatic" version of these experiences. I'm no mechanic and I barely understand how this ESS works, but to me it seems like the complete meltdown condition happens when the ESS goes to start the engine and switch back to the main battery and the main battery does not have the cranking amps to start the engine quickly enough to have the load transferred back to it. This results in sensors not being powered fully or at all, the ECU freaking out because it can't see sensors or it gets readings that indicate complete failure, and then the ECU sticking the car into "limp" mode. You may not notice the battery's in need of replacement if you don't use the ESS or if it's not consistently near or below freezing outside. All of the batteries I've replaced in previous vehicles I did so after noticing it struggled more in the winter months with starting the car, and even in this case with my Compass it didn't seem to be struggling more than usual so my usual warning signs were not there even though the battery was due for replacement.
If there's anyone else that can elaborate at all on anything I said or correct anything I am wrong about, please chime in. I'd love to be able to actually fully understand this system.
Side note: It is kind of funny to me that this issue seems to be most common with the 2018 Compass models, which seems to follow along with the issues with the Renegade's AC system where they weren't getting enough refrigerant put into the system at the factory. Seems Jeep had a few bugs to work out of these models

Are you actually getting the "Stop Safely Vehicle Will Shut Off Soon" message that the OP is getting? If not, I suspect your problem and theirs are not related.

Out of all the panicked messages mine threw at me I don't think that was one of them when I stop and think about it. I read the beginning of this thread more closely and realized I saw a couple references to what my post was about and just kind of ran with it. I think it's still relevant though because it's just more things that can happen with the battery system that people should be aware of, but you're right my response was not based on experiencing the actual problem in the original post.

I am also having the same issue with my 2018 Jeep Compass Trailhawk with less than 100k miles. I tried to message @JeepCares but the site won’t allow me to do so. Just got this car in August of 2021, so frustrating all the problems this make and model has.
Now that you've made a post you should be able to send a message.
Welcome, Emily! Many auto parts stores will run a diagnosis for free. They will tell you what the codes are and what they mean. How it gets fixed is up to you. @JeepCares will intercede if you have a warranty problem or if a dealer isn't treating you right. However, once you're out of the warranty period you'll probably have to pay to get it fixed.
Once a car is past 100,000 miles, things probably will go wrong with a vehicle -- Jeep or any other brand. I've had some vehicles that went twice that far with no problems, and some were a nightmare at half your miles. That's just the luck of the draw.
Once you get it fixed, please tell us what the problem was. That helps all of us on the site.

Hi I am having trouble with my 2017 Jeep Compass TrailHawk. It is telling me to stop safely vehicle will shut off soon. Once it does that and I keep driving it turns off the A/C first then the dashboard for the radio. Then throws a lot of different signs and lights telling me that things are turning off. The engine light turns on and the transmission says it needs to be serviced. I did in the beginning pull over and turn off the vehicle. I had it checked at several shops and they can not find the problem. In the beginning when I pulled over and turned the Jeep off and back on the lights for the shut off soon we’re gone. But it has gotten more and more severe and problems. I changed both batteries like the Jeep dealership near me said to do and it is still having problems.
