Hell that's a good thing it don't do that BS lol

 

Biggest scam ever IMHO......I hate it and just purchased the ASS eliminator for my 2026 ZR2.

This was an Obama administration thing to help the environment. Have you installed the eliminator yet and if so was it a big deal.

 

On balance, I like Auto Stop. So, not happy to see it stop working a couple weeks ago. Took my ’23 TB into dealership, and after an hour or so the tech came up with the culprit: a voltage sensor associated with the battery had failed. So, ordered the part. This loss appears to affect no other aspect of drivability.
I did ask his opinion of Auto Stop. He said GM is adamant about there being no problem with repeated "dry starts”. He did say that he has turned this function off in his vehicle, b/c he is convinced it reduces starter longevity - both concerns shared by a host of forum posters.
A skeptic might conclude that GM has timed the long term effects of the Auto Stop (engine wear/failed starter), to kick in a year or so after the warranties expire.
Going forward, I may try to develop practice of engaging it, when approaching a stop that may leave the engine idling for a prolonged interval ( > 30-40 seconds).

Let us know if this voltage sensor fixes your issue.
How many starters has your mechanic has had to replace per year and on average the mileage on them?

I think we had 220,000 miles on a vehicle with start stop and it always worked with no issues. 45,000 on 7 year old Jeep now,
I will ask my gym friend who is over a number of national chain repair shops what he see's.

I wish mine worked more often than it does, only after a long trip on the highway for a day or so..maybe I have a bad voltage sensor, or maybe the sensor is set to high..


If a person knows he is going to have to gun it, just slightly power brake, it will stay running,
most people do not know what that is though..

At this point, I would argue that the Stop/Start function probably is less damaging to the starter and more damaging to an engine. Does it mean an engine last 175K miles rather than 200K? No way to really evaluate that.

Because of Stop/Start and the complicated way Jeep implemented it on my wife's Wrangler, there are now two batteries and the recommendation is to replace both when one fails. So, instead of a $300 battery at Autozone, you are looking at $500 for two batteries at Autozone. (The Walmart main battery I chose for my wife's Wrangler still set me back $200. )

I turn off the Stop/Start pretty much every time I start either my Silverado or the Wrangler.

As far as your vehicle's Stop/Start function, I wonder if you will see a more frequent operation when it cools down. On 100 degree days in Texas te AC requirements keep it from kicking in very often.

About time this add on is available. Highly recommended.

 

...Took my ’23 TB into dealership, and after an hour or so the tech came up with the culprit: a voltage sensor...

Which sensor is it? I will take a hammer to mine!

 

That's what I'm thinking too! If the sensor fixes it and having it down caused no other issue, then breaking it's function is the fix we've been looking for to get rid of stop/start.

 

I have not seen my a/s work since early last fall and would only work after driving over 30 minutes.
I had my dealer check it anyway for the 2 times. The first time he updated something for a parasitic draw, it started to work, the second time he said I don't drive enough (which is true) and suggested a trickle charger.
I don't care one way or another, but I would like the option of turning it off if needed.

Early days of Auto Start Stop were WAY Different then nowadays
Back then yes it was tough of Starters....
Oh wait starters used to wear out a lot anyways
The newer Generation Staters that all vehicles are using seldom need replacing

You mention "Dry Start"
Are you talking about Lack of Oil at Start Up?
If so.... How much Oil could possible Drain Back in the 2 Minutes that the Engine would be Off before restarting?
There would be no issue

Auto Start/Stop has not shortened the Life of Engines or Starters for about 2 Decades now
And it used to be starters that they would kill

 

Been reading through this thread, mainly for amusement purposes. Thank the Lord my 2022 Colorado V6 does NOT have this feature. I realize most think this feature really does no harm, but maybe just try thinking logically about this... "dry" starts are the enemy of any engine, and this fact has been documented by lab (ppm lead in the oil) testing/analysis. Lead in the samples...the thing is, it can only come from ONE source in an engine--and that is the main and rod bearings. Also think about the auto transmission--start/stop simply cannot be good for the clutches, as it takes a bit for the hydraulic pump to build sufficient "clamping" pressure on the clutch packs. With all the trans troubles we read about here and on other forums, do we really need this added to the mix as well? Lastly, in terms of ACTUAL fuel saved, can anyone point me towards a study where the fuel saving is actually QUANTIFIED, this for an average motorist in combined city/freeway driving? This start/stop feature CANNOT add anything to engine longevity, so the savings, IF ANY, have to be in fuel, and possibly emissions. I realize that is the stated goal. I simply would like to know what that number actually IS for the "average" motorist.

 

Theoretically you engine is not starved from oil when you are using the stop start feature. If the oil film has already disappeared after 30 seconds or 1 minutes then your oil is the problem and even with out stop start your engine will fail. The engine is also already warm by the time the computer decides the stop start feature is safe to use. With it warm and under no actual load it does no harm to the engine or the transmission. Zero.
If I shut off the stop start feature on the engine of the wife's car we use about an extra 4 litres of fuel per week. Not much but considering she has a 10 minute commute each day the savings add up. Add up all the extra revolutions the engine would be spinning every day if the stop start feature was removed completely and you may find you have increased wear in your engine.

 

My 24 ZR2 has the feature turned off and it was turned off when I purchased it new. Having said that it's active on the wife's car and works fine. The comments in this post saying it will starve an engine are hilarious, have zero data to back it up and usually come from the same people that say an aftermarket cold air intake adds 10hp on their butt dyno.
If the oil film is gone after the 30 seconds or minute you are sitting at a stop light you are using the wrong oil. I've spent over 30 years making a living as a mechanic and I have yet to see 1 engine where I can say that the auto stop start technology caused an engine failure.

How was it turned off when you purchased it?
It automatically turns on again when you restart the vehicle........at least in the USA.

 

There is no “turned off” option so your dealer must have misstated. By regulation the start/stop must rengage each time the vehicle is restarted.

In regards to actual fuel savings, yes they exists and are not insignificant. You can spend 5 min googling the studies. Evidence is pretty cut and dry. Start stop saves fuel after about 7 seconds of not idling and saves 4-9% fuel overall depending on drive cycles. Probably even better now as that is from a 21 year old study.

Start stop does not engage unless engine is at temp and not under load. This means these are not “cold”/“dry” starts. The wear put on your engine in a start/stop condition is not comparable to normal startup.

Starters are designed and validated with start/stop in mind. If you want to spend 4-9% more on fuel over 300k+ miles to extend the life of a $200 starter from 300k miles to 1M miles then feel free but that math ain’t mathing right. The fuel savings will pay for that replacement starter that is unlikely to fail anyway 20x over.

 

I'm not sure what my dealership did but the salesman stated they did something to make sure it doesn't work. What they did I don't know and I'm not sure what the laws about it are up here in Canada. I like the feature on my wife's VW. I just don't use my ZR2 enough to notice a difference.

 

My question to anyone here who has the auto start/stop feature.

1) On a hot summer day with the Air Conditioning running how does the start stop feature maintain the air conditioning cool temperatures when the engine is not running?

2) The same question when running the heater on a cold winter day?

Both questions require the engine to run for the Air Conditioning compressor and the engine running to circulate the coolant through the heater core.

When there are any excess demand, A/C and I assume heat, it does not work. If the battery is low, it won't either, which is the main reason for mine not working. There is a blurb on it in the manual.

 

There are a long list of preconditions that have to be met for the engine to auto stop. Low heat and AC load are one of them. See page 164 in the owners manual.

 

Im not sure about your specific driving habits, but you may actually notice an increase in fuel economy. I did some experiments with my truck and found i was getting noticeably better fuel economy with it off 100% of the time

 

You would be an anomaly and a case study in and by itself. Every study I have read shows increased fuel economy by using the stop start feature.

 

So much debate on the auto stop feature. I personally like it. To simply put it I use it when I am the first or nearly the first at a light when the light is 5 minutes long. Mine times out actually the lights are so darn long where I live and the truck starts up before the light changes anyway. I just push the button to turn it off when I am at a short light, or I know it's about to change. I also turn it off when I am parking and will stop the truck, back up, etc. so it won't shut off. The start/stop does not always work either....if the battery is low due to the truck sitting for a day or two it won't work until the battery charges up. So I use it but practically when I want to. The button is there to turn it off, I don't understand all the hate.

 

Auto start/stop is not for the vehicle owner it is for the vehicle manufacturer. You save 0.24 to 0.5 mpg per tank and 1mpg with extreme stop and go traffic which does nothing for you but the pollution it saves per hundred thousand 3rd gens they sell each year gets them eco points from the government. So they don't care if you have to buy starts more, or the extra wear and tear on your turbo and motor will make it need maintenance/repair/replacing sooner because they also hope to sell you the parts and the labor since all of this should happen right out of the 3yr warranty

 

Where I live I need to enter a busy 65 MPH highway from a dead stop with no acceleration lane........
On my Silverado, many times I'm sitting there waiting to go with busy traffic, finally an opening, go to stomp on the gas and the engine quits then starts again immediately.
Not only unnerving but that just cannot be good for an engine, I don't care what anyone says.

It's a total joke.......give owners the option to turn it off permanently!
I purchased the ASS disabler for my new 2026 ZR2.....I don't want to deal with it.

 

I personally hate it, and the first thing I do when I get in any vehicle that has it is look for that button to shut it off. There’s something I find extremely off-putting about the car having to do something else before it actually goes when I step on the gas. My wife on the other hand doesn’t mind it and kept it on in our last car that had it. Used to drive me nuts.

 

I wish that my auto-stop would stop working.. i manually turn it off every time i get in my truck. the service manager at my dealership told me that because i drive short distances to work (15mins) it could be harming my battery by not letting it get back to full charge by the time i park. my battery was replaced after 6000km (3700miles) and i believe it was faulty from the factory, but the dealer seemed to say that they see this often and battery condition appears to be related to auto-stop/start in their opinion.
I am afraid to try any "hacks" i have seen to disable it because i don't want to deal with potential side effects.

 

Short trips are probably doing the harm, A/S doesn't work till the engine reaches operating temp and battery is almost fully charged from what I gather. Try leaving it on and see if it operates and when, not that you seem to want it anyway.

 

It's not GM that wants that junk, including AFM. It's the government tree huggers costing auto makers and mostly us millions to meet EPA requirements .

 

If we remember the government requires auto start/stop, there's the starting point.
GM has pretty much all the settings programmed so you have to have the engine running to see or set them. I'm thinking it takes quite a few start/stops to offset a single session of going through the settings. This includes resetting the oil life monitor, back seat reminder, teen driver mode, etc. Also, it doesn't stop if the A/C (including defrost) is on, the engine isn't warm or is too warm, or it is in tow/haul mode.

 

Yes my 23 GMC Canyon Denali had problem with auto stop , ended up changed battery, said was defective, after 6 mths of complaints, fixed it
I agree it is extra wear on starter, pre mature replacement

I talked to an Auto Zone employee. He said they love Autostop. They have a huge increase in battery sales since the proliferation of AS.

 

I just turn it off and then on for a known long light. I believe repeated starts would be bad. Its not a traditional starter but I wouldn’t use it stopping every few yards. Also, I don’t use it when the engine is still cold. Get the oil warmed up first.

 

Why is a separate eliminator needed? I swear mine has a button to turn it on or off.

Why is a separate **** off needed? I swear my 2024 has a big button to toggle it on or off

Because it needs be turned off every single time you start the vehicle......and half the time I forget and there I am getting irritated the truck is shutting off again.
I actually consider the ASS system a safety issue under certain situations.

The eliminator automatically turns the ASS off every single time you start the vehicle, just like it was never there to begin with.
