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.

I average between 25-28mpg auto-stop off 100% of the time. I know i average on the very high end of fuel economy in general.

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.

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

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.

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).

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.

I put one in Terrain. 5 minutes to install. Then just wait about 20 - 30 minutes for system to see it. Worked flawlessly.

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.

I remember, years ago, they said that starting an engine used more gas than letting it idle for two minutes. So, if that's the case, we are not saving any money on gas by using the auto stop, mostly likely spending more actually. I also believe that repeated usage of a starter, will cause it to wear out faster. All things mechanical have a limited number of uses and using it more than normal just makes sense that it would wear out faster. I turn mine off every time I get in my truck. Just my opinion.

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.

 

[Powderski]

Keep the politics out, please and thank you

No politics, just a fact. Got to protect the environment No? There are no outright laws banning or requiring "auto stop" (or auto start/stop) technology in cars; however, the U.S. Environmental Protection Agency (EPA) is proposing to eliminate federal incentives and credits for this feature, which could lead automakers to stop including it in future vehicles. The move, announced by EPA Administrator Lee Zeldin in May 2025, is a response to consumer complaints and a broader deregulation effort, as the feature is often unpopular and does not provide significant fuel savings or emissions reductions to justify the costs and potential wear on vehicle components

 

[Powderski]

It comes on when started and the preference is to remain off when started.
