Why? I really don't see why this would be a problem in this situation. The motor is running again before your foot gets to the throttle.

Thanks for the responses of those that own Cherokee's with ESS!
Maybe I'm old-school (though I am young..), I like knowing I have power immediately when I need it. When I let off the brake, I want immediately forward acceleration.

Don't get me wrong - ESS has its benefits in areas where gas is expensive (Europe) and for city driving. I just prefer keeping the engine running and doing it's thing when I'm in the vehicle, rather than shutting off for a few seconds to save a couple drops of fuel. Fortunately it can be disabled, but from my experience it's more of an annoyance than a benefit.

Interesting comment. It would be nice to quantify it. Is it a few drops, a splash, a shot, a gulp, a chug-a-lug? How much gasoline is consumed by the V6 at idle per second?

I had to chuckle at that. We're opposites! I'm almost 64 but I've always liked new technology. Not brand new (that can get you burned) but I'm generally a fairly early adopter. I have a '09 Challenger R/T and one of the reasons I got it is the MDS that shuts off 4 cylinders when cruising. When I got the car it would get a solid 25 mpg on the highway, which is pretty good for a 4000 lb+ car with a 375 horsepower Hemi. Who would have imagined that in the 1960's! Anyway, I've done some work on the motor and switched to bigger tires, but it still gets around 23 on the highway.

I live in a suburban area outside of Philly, and too often I find myself sitting at traffic lights, wasting gas. I've been waiting for ESS systems to go mainstream and it's one of the reasons I'm considering a new Cherokee. That and it's towing capacity/power are big selling points. The styling is growing on me. I do wish it had more storage space in back but I have a nice 5X8 utility trailer if I have to haul big stuff.

On a related topic, it will be interesting to see how owners of the new Chrysler 200 will like it with ESS. Since that car has ESS only on it's 4 banger, I think the 'feel' will be more pronounced when it turns off/on. I just saw a new 200 out in the wild for the first time yesterday. It looked kind of Accord-ish but it looked good. I like the shifter (a round knob).

There is a video around where a representative or engineer from Jeep says that the ESS helps saving about 3% of fuel on the V6 Cherokee...

I have observed earlier that I don't notice my ESS much. Today I turned it off for the first time, and, to me at least, it seemed to make the car drive more enjoyably and smoothly -- not markedly so but enough that I am tempted to do it on a regular basis. Seems to me it will also be easier on the car and its battery, and what am I losing? 3% gas saving is not much for me, meaningful as it may be to Chrysler, which is trying to wring every possible mpg improvement out of its cars.

Hello all. I signed up here to learn more about a feature I did not know existed in our new 2015. All the test driving we did I either never come to a complete stop, we were on the freeway just due to the dealerships location. We did not have stop signs or stop lights around the dealership during our extensive test drive. As for the Stop/Start I actually found this site as a search for it. We are disappointed to say the least. It is dangerous in my opinion. We park close to a wall inside my garage, pulled into the garage, was chatting with wife, realized engine was off, let foot off brake and of course we went forward. This is NOT a feature we will "adjust to", and having to shut if off every time you start it stinks. I hate the AC getting hot and switching so the hot air dont blow in you're face while at a stop light as well. We have had our jeep 2 days and are ready to scream. The headlights have moisture in them (both), their is a horrible side to side wobble from a dead stop (which we never felt due to never having to stop on test drive), and this idiot stop/start. I hate making a first post one of complaints, but seeing this sort of is giving me a place to unload. $35K vehicle, one of 7 brand new ones I have owned, first ever Jeep, and I cannot stand to drive it. The side to side aggressive wobble from a stop is so bad it shakes the headlights. WE have a brand spanking new 2015 Limited V-6 9spd auto. Any help would be deeply appreciated. I am calling our dealer first thing in the AM.

Wow! Check your state "buyers remorse law" and see if you can cancel the sale quickly because all your going to be is unhappy and compiling.

We leased it. Traded our 2013 Challenger in due to our location and winter weather, Challenger was not the best option we could have made, but Im a mopar guy, and we figured it would be ok with having 2 other 4X4's. Wife wanted a small suv so we of course went back to our mopar dealer. I love my mopars dearly, worked for Dodge as a tech. As i stated this is not our first brand new vehicle, and knock on wood have not used warranty on any previous outside of one minor power steering hose leak. I have all intentions of making this a driver for 3 yrs, but we have to get past 3 days first. I am far from one to have extensive unjustified complaints, and my prior vehicle ownership is proof of that. But this is a tri-fecta right out of the gate. I sort of was in hopes that a Jeep forum may have some answers in support of their product rather then tell someone who is disappointed to go turn it back in

I have 2015 V6,4x4, ESS on mine has shutdown twice at the traffic lights. I had to shift to Park, restart the car. Hope this is just a hiccup with so brand new car (less than 100 miles so far). Any thoughts?

Please explain. Isn't it supposed to shut down at traffic lights? Are you saying the engine would not restart when you took your foot off the brake?
