Have a 2019 ICE Pacifica on order.After looking thru these forums it seems evident that there are a lot of problems with the ESS system and batteries.I am not a fan of that system,usually keep vehicles a long time.Can’t see replacing starters and batteries over a period of time just to have a minimal savings on fuel.This system is not to be confused with a true hybrid system that have much larger capacity batteries,and due not use the small starter to restart the engine.Wondering if anyone tried (with the factory tow system) plugging in a 7 to 4 plug adapter and not having to remember to turn off manually the ESS system,if that works.It does function on some other vehicles.Appreciate any input. Thanks

Though I can't prove it, as I do not own a gas Pacifica, it stands to reason that Chrysler would have specifically upgraded the battery, starter, and anything else involved in the ESS system. They are not the first to implement an ESS system (it been around for years in other manufacturer's luxury vehicles), and I seem to recall another topic on here covering the same worry about part longevity with them. Similarly, it was unfounded.

Disabling it for a perceived extra part longevity, especially when batteries are already a normal wear component anyway, seems to be a terrible idea. Also, forcing the van to run unnecessarily when stopped will only add to pollution. Adding needlessly to the world's pollution level, especially when lead-acid batteries are so thoroughly recyclable, seems stupid, especially when driving a vehicle intended for families. "Here, son/daughter, let's add to the pollution you'll need to deal with when you grow up!"

Thank you for the input.I am still trying to find a restaurant that does not use plastic straws.
From a veteran and and an elderly grandfather.
I'm not sure how that applies to this topic, but if you don't like plastic straws, you can always buy (and remember to bring) your own cleanable and reusable metal straws. Also, some restaurants are starting to use waxed paper straws, in place of plastic straws, in some areas.

If you’re going to keep it a long time just buy a lifetime warranty from the Chrysler factory. You have to ask for it - they won’t tell you about them because stealerships don’t make money on them like they do 3rd party warranty companies that give them commission. You can buy a lifetime warranty up to 48k miles / 48 months - whatever comes first. There are different levels and different deductibles to choose from.

Browse around this site to views more details but i’d Buy it thru your dealer.

Thank you.👍
Anytime, allot of my family work at the Belvidere, IL plant that's the only reason I ever came to know about it. Though at the time I found out was about 4 months too late for our jeep patriot :( . Warranty can be purchased for any chrysler, dodge, jeep, fiat products with a few exceptions of SRT and hellcats ect...
Enjoy your new pacifica, I love mine.

I wouldn’t say it’s evident that the ESS system on the Pacifica has a lot of problems. There’s a handful of people who have had issues with it, but considering how many of these vans have been sold I’d say the percentage of folks having trouble with it is quite small. I’ve never experienced a hiccup on ours and we’ve had our 2018 since September 2017.

There’s a separate AGM battery installed to handle the load of the electronics and HVAC blower when the ESS activates at a stop light. If the charge on that AGM battery is not sufficient the ESS will not activate. Although I’ve never seen ours not activate due to insufficient charge. Also, the starter in ESS equipped Pacifica’s is rated to handle 10x more start cycles than a standard starter.

Here’s a good article that explains the benefits of AGM batteries in this type of application.

Also a video from Chrysler regarding the Pacifica’s ESS system.

My dealer offered the Chrysler extended warranty but I passed due to the high price. Then I found a lower price on this forum from another dealer. If the OP is interested in the extended warranty I suggest a search of this forum to find the dealers with the best pricing. The extended warranty can be purchased from any dealer. It does not have to be the dealer you purchased the van from.

I purchased my Pacifica in Delaware,where I reside for 4 months every year. Primary residence ,drivers licence,car registration etc so on
are ,and have been Florida.Chrysler (Mopar) warranties say due to Fl. regulations ,warranty must be purchased thru a Florida dealer.Florida dealer warranties are much more expensive .Therefor Chrysler will not deal with me thru their site. Will have to canvas Fl. dealers in Oct. when I return .Thanks for the input.

I read here somewhere that there's a device sold that disables ESS but I just push the bitton manually every time. I'm not concerned with ESS reliability, I just loathe the van shutting off at stops.

SmartStopStart. Kinda pricey, but customers like it.

Check out the reviews on the new eTorque system FCA is using on the RAM 1500’s (including the 3.6L Pentastar V6). Very slick. It’s technically considered a mild hybrid, but the cost is probably very similar to the current ESS system in our Pacifica. Not only would it make ESS not noticeable, but it improves fuel economy even more than the current system because it uses a mild form of regenerative braking along with electric motor torque to help you off the line and when the transmission shifts/downshifts. Maybe in the 2020 model.

Sounds interesting:

It's called gentle rib poking humor, SBC. I thought it was clever. :wink2:

For the first time yesterday, I saw those metal straws at Walmart. I blanched at the thought of some child sipping his juicy cup while riding in his safety seat, and Mommy makes a sudden emergency stop, and the environmentally friendly metal straw rams through his gullet. But it is cleanable and reusable. (That's called snarky satire.)

Blind decisions by advocacy groups often have unintended consequences. ESS has some problems too. Extra parts and batteries have to be manufactured for the vehicle at an environmental cost. The engine itself emits an extra puff of exhaust when it restarts, often after a very short down time (I know, I drive a Pacifica). How long before the down time compensates for the restart pollution? I'm pretty sure sure these question are of minor consideration to the manufacturers compared to the sales benefit of 1-2 MPG shown on the Monroney sticker.
