From what I understand, Jeep have always had a very successful stop system, it's the start system they've struggled with !!!!!!!!!
XD Very true.
good one
so funny I suppose thats why our jeep grand cherokee has lasted so long
Jordan Gehlhausen Well, if it doesn't run, it's not going to wear out, is it ???? ;-)))
We'll our Jeep runs perfectly fine. It starts up very quickly. From what I understand they have a beefed up alternator and either a separate battery or a more durable one as well as a stronger longer lasting starter.
What the reviewer does not tell you is the button that disables the start/stop system must be turned off EVERY time you drive the vehicle. The buttons default position is ON!
Pretty cool tech but I, like others, wonder about the extra wear and tear on the engine. In rush hour traffic, this start/stop feature can occur dozens of times. And I also wonder what would happen if it stopped but wouldn't start. Good thing it's defeatable.
Yes, it probable saves petrol.... But long term, all that wear and tear on the starter starter motor & battery etc would surely be more expensive then the petrol/gas savings... :(
John Person,
For saving fuel, there is more than just the financial aspect.
Does engine stop start technology increase the wear and tear on the cars starter motor, alternator and battery?
Nathan , i love your reviews.
Nathan, why did you think anyone following TFL would be interested in demo of a start-stop system? Automotive journalists have been complaining about BMW's system for close to 3 years.
The new exhaust tips look really good too
For the Start/Stop System, the alternator is engineered to withstand frequent starting and stopping of the engine. No it won't have too much engine wear, because most oils used today in modern vehicles are either synthetic blend oil or full synthetic oil.
Problems to consider, most of the cars using this have special AGM batteries that are expensive, so some of your fuel saving will be lost there. Diesels don't like short runs at the best of times. Start stop on a diesel will make DPF filters more prone to clogging than they already are.
I have it on my 2015 TH..only offered on the V6..they use a AGM Battery, special starter and heavy duty flywheel to accommodate this action..restarts in 0.3 seconds after your foot comes off the brake..system won't stop engine if the engine is cold, senses battery is low..steering wheel is turning..time and speed don't pass threshold since last restart (won't shut off if you are creeping and stopping constantly)..was weird at first but I'm use to it now..starts and goes as fast as you can get your foot from the brake to the gas.. {:^)>
Does it really save petrol? I mean, starting the engine uses a pretty good amount of fuel on its own... correct me if I'm wrong.
On 29April I tested and purchased a new Cherokee and the ESS is not ready for prime-time yet. I will buy the Smart Start-Stop module for $125. Until then, the ESS will be turned off before driving.
Hope someone can answer this, Won't the constant starting cause the starter to wear out quicker?
My wife exact car, 2015 Cherokee has problems with that stop start feature, the car is dangerous it will stall or hesitate at the most inopportune times, Id like to see you do a video about that. Dealer and Manufacturer are not willing to acknowledge problem, we think its this stop start feature that is doing it, but problem does not go away when you disable it. Car is 3 months old, and we like it except that feature which could mean problems down the road, a new car should not hesitate and stall at a circle, or when you are trying to get out of the way of something in a hurry. It must have something to do with this hi tech feature, which in our case means the Lemon Law.
Figure out how to do it. Start the car, do not disable the function. Put car in drive, drive to a stop. Engine now shuts off with your foot on the brake. Without taking your foot off the brake, shift into Neutral, I don't remember what I did next, either shifted back into drive or took my foot off the brake. Car restarted & now I noticed that I no longer have to disable it. It will no longer shut down. Don't ask me how to re-enable it. It's a lease so I really don't care.
Nathan, is the engine start-stop system in the 2.4L Tigershark Inline-4 or the 3.2L Pentastar V-6, or both?
Just the 3.2-liter Pentastar V-6 in the Jeep - but Chrysler is adding it to a few four-cylinder engines (other than Jeep) too.
nathan adlen is it only available on the 2015 and not on the 2014
crazy wheel only 2015 (I have a 2014)
Cliff Hartle could you tell me if a 5'10 " , 200 pounds adult can fit on the back seat, I'm considering to buy a cherokee or a grand cherokee not right now, I have all ready 3 cars, I think the cherokee is big enough for me but I'm not sure
crazy wheel I am taller and heavier, yet I fit behind myself fairly comfortably. I have stubby legs; so if you have long legs, you should consider sitting in a few first.
How much is a new starter worth? It is going to wear out a hell of a lot quicker. I can just imagine some fool using it in the winter and coming out of work and the battery is dead. If you have a short drive to work it isn't enough to keep the battery charged in cold weather. Repeated use of the starter plus lights and heater fans could prove to be a problem. Says a fellow from The Great White North.
Excellent! Thanks! I'm a machanic, thier's no licence for fixing stupid! It is a problem at traffic lights!
The most sludge in the engine occurs at start stop and if at each stop the engine would shut off it takes more fuel to start than to run for 2 seconds at a stop sign.not even talking about poor starter,and how it might be failing after just 50k M.
At least Chrysler is smart enough to put in an override switch. Shows full confidence their new fancy start-stop system lol. I mean really just look at the electronic errors the JGC has and early transmission problems the Cherokee had, do you really want another thing that could potentially go wrong?
would be helpful to show screen shot of button
Wouldnt starting the car again waste more gas then just having it idle? And that system must destroy the life span of the starter
I'm pretty sure.
In the case of this video its hard to get an impression how a start stop system would be effective. But think of when you're at a red light for 2 plus minutes or even longer. I bet it is more beneficial to have the engine turned off.
Someone else posted that it has two starters and I think that whole "have to be stopped more than x minutes to make it worth it to stop the car because starting a car uses more gas" doesn't apply to today's cars. (Might have been a carburetor issue?)
Its been posted that it uses 3% less gas.
If you guys want some more information on the system follow this link

It depends on how long you are stopped.. like at a stoplight this would save fuel or a traffic jam
Mine triggers a stop/start error/malfunction light and turns on the engine light. When I turn the car off, it resets the s/s/malfunction light and SOMETIMES resets the engine light, but not always. Then in the next stop or few, it triggers the s/s/malfuction light and the engine light again.
2015 Jeep Cherokee Engine Start-Stop AC Off System Revealed
I noticed that the
start stop engine only works when you wear your seatbelt.
Wa-alykum As-slaam! Nathan 👍👍
im wondering if the start stop system is hard on the starter..?
I'd like to think that the engineers thought through the wear and tear on the alternator/starter/battery. I'm sure the thought crossed their minds even without the benefit of youtube commentators.
It's the delay in power, like merging onto a highway or circle/roundabout (if you're lucky enough to have them in you region) I'd be worried about.
we'd all like to think that,..but this is Chrysler/ Jeep were talking about here lol
Yeah they thought through it alright:
"Will the starting system make it through the warranty period?"
"Most of the time, yes."
"It's a go!"
They don't give a crap about after the warranty expires.
Does anybody know how long the engine stays off for when in this condition? I ask because when I come to a complete stop the engine will shut off, the problem is without releasing the break or touching the wheel the engine comes back on it's own after a short amount of time. Is this normal? I can't find anywhere that it says the ESS only shuts the engine down for a certain duration. Thanks.
How does it save fuel when you stop at a stop sign for 3 seconds...... Then he says in traffic it would be annoying so just turn the radio up. Ok so drain your battery and excessively use your starter so you can save a piss of gas. Look up the cost and labor on a new starter and battery. Then consider the time you waste having those two things in the vehicle replaced more often than they should be.
what interior color is that? ive never seen that color on a cherokee
Safety issue in the US - wouldn't want my engine stopping in certain parts of town, seems like there's a good amount of delay incurred between an attempted carjack and hightailing out of there. Enough to the point between the difference of life and death. Not sure if it's worth saving that whopping $20 of gas over the lifetime of the vehicle by using this feature.
Would this wear spark plugs and sort of stuffs?
So if you live in the city your engine will probably have half the life do to all the wear of consistently starting and turning your engine off.
i think in traffic you'd be better off turning that off. it seems like this would be great in more rural places because you're not stopping and starting as often
Not if you turn it off genius.
jlen82 wear of starting an engine is mostly on a cold engine, especially when the oil has drained back to the oil pan
jlen82,
Idling also generates wear on an engine.
Do a honda accord coupe 2014 review please
oh brother........ why didn't they just make a hybrid version instead of cutting off the engine? It seems silly to me, but oh well!
Hybrid systems, especially on the highway can cut efficiency. Instead of a motor with ample power just pulling the weight of the car, you end up with an underpowered motor pulling the weight of a car and a hybrid system.
inster will hybrids are almost never more efficient on the highway/interstate. only in the city do you see any benefit
Clay Martin Yea, that makes sense!
inster will yeah:) because typically they run on mostly battery power at low speeds and that's where the fuel savings come in
Think about cost! For a hybrid system.
please do video on the other tech,, lane keep assist,,, yaaaaaaaaaaaaa
Personally I don’t like this feature scared the crap out of me when you don’t know it’s equipped with it it stopped and I thought my Jeep broke down and died until I pressed the gas lol
It will keep you mechanic well paid replacing your starter motor every year.
If your running an electric motors yeah it will be ok but petrol one your wasting your starter, battery, and engine.
where is the start stop battery?
Won't this just wear out started way too fast in city traffic?
Doesn't it kill the electric starter
Review this car!!!!
That would kill the battery very quickly
Yeap in 3 years
Thats new jeep?? it looks like a honda
Nah. It looks nothing like a honda.
we have this in our new Malibu, it's barley noticeable.
Could have at least told us how to start the damn thing
James Sampson YES I HAVE A RENTAL AND IT;S DRIVING ME CRAZY!!
We hate this function and wish we could permanently disable its operation. We are trading dollars for gas and gas for fun; saving fuel is of no concern to us.
Figure out how to do it. Start the car, do not disable the function. Put car in drive, drive to a stop. Engine now shuts off with your foot on the brake. Without taking your foot off the brake, shift into Neutral, I don't remember what I did next, either shifted back into drive or took my foot off the brake. Car restarted & now I noticed that I no longer have to disable it. It will no longer shut down. Don't ask me how to re-enable it. It's a lease so I really don't care.
Kerry Logan,
If you find the feature distasteful, you could always find a different vehicle, or use the button to turn it off; personally, I would love a vehicle with such a system, though I would not purchase a Jeep.
Thanks, I will give that a try.
I have numerous cars and find this feature to be just a source of irritation on such a very nice Jeep. Funny, I had a rental car of the same type and it did not have such a feature.
وعليكم السلام ههههههههههه good
هاي سويج ما بيها وعجلاتها من نوع fuim
Let's see real jeeps not hubris that sucks and looks ulgy today
How stupid. Really, to save fuel? To help the environment? How ridiculous, if you can't afford the gas, then get a bicycle or motorcycle. This lets help the environment bandwagon is so small minded and absurd.
phosphodiesterase I am an eco-freak and I agree that the better options are bicycles and the like. However, do you understand how utterly impractical that is in America? I live in the suburbs in NJ, and there is absolutely no way I can get around with a bicycle, and I will not run the risks of riding a motorcycle. Jeep made a step in the right direction, and I applaud them for doing so. For now, this is the type of feature all new cars should have. That is, until all cars can become electric or at least hybrids.
jeff cowen Yes right now for fuel saving I think they have exhausted all the low hanging fruit and now can only chip away in tiny bites until something like hydrogen fuels cells can be practical. (Note I have no idea if hydrogen fuels cells are the right direction, it was just an example)
Cliff Hartle I don't know either. I think we'll be seeing a lot of solar panels integrated into cars' roofs in the upcoming years. The Prius has one to turn on a fan, but perhaps other car makers can use them to power, say an electric backup engine.
jeff cowen I don't think there are enough watts of power from sunlight hitting a car to actually power anything useful. They have had competitions and they can only get a light go cart moving.
Cliff Hartle Oh, I didn't know that. Maybe a future model will do better. New renewable energy-based technology is improving each year.
No thanks. I'll turn the car off when I'm ready.
Foolishness
Holy Shit what a Stupid system...Saves Fuel ??,,Heck Oil will be around another 500+ yrs...so who gives a Rats Ass....The Cherokee is nice though...needless to say this button will never be used.
WORST CAR EVER!!!
That is one ugly Honda, I mean Jeep.
For the Start/Stop System, the alternator is engineered to withstand frequent starting and stopping of the engine. No it won't have too much engine wear, because most oils used today in modern vehicles are either synthetic blend oil or full synthetic oil.
