I'm reserving judgement until I hear more reports from the field. If it's just like the Cherokee's ESS system, I'll be glad my Pacifica doesn't have it. If it's a little more refined, and does indeed save gas, I may be disappointed that I didn't end up with it. But I don't feel strongly enough either way that it would have swayed my purchasing decision.I am glad that my Pacifica doesn't have this function.

Adding nothing useful to the discussion, I've got a limited on order for about a month now. Got the window sticker a day or two ago and see that ESS is listed as being installed. Goes with an "auxiliary" battery, but no further info.
I know people driving BMWs with their version of it installed who were less than thrilled with it. OTOH, and much to my wife's dismay, I often turn off my car while sitting at some of our obscenely long lights. I may well revise my opinion when (if?) my new van arrives, but I'm kind of jazzed with the concept of ESS. Hope reality doesn't deflate too badly...

I had post a few posts on the details of this system. I am curious to see if it is indeed Johnson Control's ESS system. They have regenerative braking that charges up a battery for aux use when stopped at a stop light This might be apart of that second battery. I also know that the ESS bypasses the starter and gives the car an electric start of sorts. I am tired, do not recall all the details, but it gives a quicker start. They also have an alternator that decouples when battery is done charging. I'll have to find those posts and put them here.
With that said, at first I was against this, but now that I have done my research, I am excited (like standing in line for Star Tours at Disneyland) to see how well it works. I ordered mine Feb. 2nd. with Quick order 27J (ESS).

A sun roof and ESS were on my list of do not buy a car with those options. There were other options I did not need, but those two were show stoppers.

There are plenty of pre ESS Pacifica's out there. 8 passenger (deletes sunroof, adds 20" rims) are available. There may also be a chance that you can still order "Quick package 25J" which is the non ESS engine. At least it showed up as an option to click when I was ordering mine.
Or you can just get the ESS system and turn it off.

When the minivan stops, fuel flow is cut; higher-capacity batteries maintain in-cabin systems.
When the brake pedal is released, the engine restarts and the transmission is engaged." 2017 Chrysler Pacifica minivans: Hybrid and gasoline engine and transmission

But if you really don't want it to function at all, you'll have to turn it off every time you get in the car.

^^^ agreed. @Tsnor, the press release stats that it will be restarted again once the engine turns back on after cold start.
Thanks for your link though, I found this MOPAR ESS system on other vehicles. It is "safe" to assume that the Pacifica uses the same set up... yes, but probably with more advanced tech.

reading up on the ESS system on the 200, here are the ways you can deactivate ESS if you wish (to go to extremes on some approaches lol): "The system does not work if the driver is not buckled in or has their door open; if the battery is too hot or cold; if the car is on a steep grade; if the cabin is too hot or cold; if the defroster is on, with the fan on High; if the battery is not fully charged, the engine is not warm enough, the hood is open, maximum a/c is set, or if the brake pedal is not being fully depressed."

That would certainly disable the remote start system as well.

I finally have my Pacifica and can give you my initial impressions with ESS.
First it is hardly noticeable unless you are watching the tachometer. It starts back up quickly and really causes no delay in accelerating from a stop. I also noticed from the outside when remote starting that the starter is extremely quiet. Much quieter than any previous vehicle I've had.

.Congrats on the new arrival! I see you already updated your avatar :smile2:
It's great to hear that Chrysler seems to have done ESS right in the Pacifica. Keep us posted as you get more use out of it!

Thank you. I've already noticed some other things that seem to have been addressed as well. I will be posting on those too.

Can you provide pictures of where the extra battery is and the ESS button? My vehicle was built last week and just downloaded the window sticker today. The online owners manual has not been updated to include ESS. Did your owners manual cover the ESS feature?
If you do a YouTube video you will be the first to cover the Pacifica ESS!

Page 337 of the 6th edition describes the ESS.
Here are the pics. The aux battery is right next to the regular battery. It's just much smaller.
I'm not much of a youtoober so you'll need to settle for pics only.
