My 24 Colorado WT doesn't do it. I think it may have in the beginning, but now it doesn't come on and I like it.

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).

What does "on balance" mean? It is a horrible "feature" and serves no positive purpose whatsoever. Save $100 a year in gas? Reconsider.

You don't have to like a feature
It does serve a positive purpose

It's is like making a call and having to push one for English. Don't have it come on every time it is started. Let us turn it on when we want it.

I can't stand the down shifting in "drive" mode on the transmission of my 2023 Colorado. I have been putting it into "Manual" mode and shifting it to 8th gear. It does not down shift on hills AND the auto / stop does not work in that mode. Don't know why or if it is just my truck. Anyone else try this or have downshifting issues on hills?

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..

I have a 2024 canyon 2-wheel drive, I turned that crap off the first week thru the onboard screen. No need to replace starters, and that is not a dry start. Even when sitting for a week is not a dry start, there is still oil on the bearings. These people talk about dry starts don't know much about engines.

100%, I'm SO sick of that crap. That's biased in the extreme. Can I dial 3 for Italian? Maybe 4 for Swedish? 5 for German? Nope.

Even when sitting for a week is not a dry start, there is still oil on the bearings. These people talk about dry starts don't know much about engines.

There may be a film of oil in the bearings due to surface tension, but there is little to no oil in the oil passages so the bearings aren't pressurized. I've read several articles that stated the vast majority of engine wear occurs at startup, especially a cold start after it's been sitting. Even on a hot day after being run shortly before, I ALWAYS let it run for at least maybe 20 seconds or so to pressurize the passages/bearings. And being Old School (bought a Turbo Talon Tsi AWD new in '92) when it comes to turbos (my CR-V is also a turbo), I'll let the engine idle for maybe 10-20 seconds to let the turbo spool down before turning it off. Yes, I know that newer turbo systems have better oiling systems so you don't "coke" the oil, but I figure it can't hurt to let them spool down to idle speeds.

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

The button ONLY turns it off after you press it. You turn the truck off, then you have to press it AGAIN, you have to do this EVERY time you start it, there's no way to turn it off permanently without an aftermarket part.

See post #31 of this thread, apparently it can be turned off, by the dealer, details on what and how are missing though. No light on at start up, no confirmation if it can me turned on if desired..

Not sure where this was proven to be the case at all.......
HIs isn't working, doesn't mean his dealer did anything but turn it off for that specific drive.

If it was that easy it would be all over this forum........got my ASS disabler today. Installing this weekend and I'll provide an update here on how it works.

But the same argument can be made by the person who wants it on all the time
And if it had to be turned on all the time... Why would they have to turn it on all the time

There is 2 sides to that one

I cannot confirm one way or another since its not my truck, I figured it just wasn't working due to lack of truck use. But he does confirm the light is off at start up.. so ?
I find it equally strange a dealer would mod a stock gm system, then again, too many computers

I’m pretty sure he meant to allow the owner to enable/disable the current functionality.
Or have it save the last setting upon startup…..

Not have you forced to deal with this BS when you don’t want it

Must be some government mandate, not a computer program expert, but if I can tell my truck to heat my steering wheel at start up during winter, and not during summer, or put on my seatbelts before I go into drive, A/S shouldn't be much different.
I still don't care one way or another, no hesitation when it did work, worked as intended, and found I could kill it with just using the brake when I came to a stop if I wished.

I'm also in the camp of "dry start = not good for engine lubrication [over time]". I wonder if A/SS is a contributor to the grenade issues the Silverado 5.3 + 6.2 V8s are facing. Word is it is the AFM/DFM systems; but the 'fix' is apparently replacing the 0w-40 oil with 5w-30 or 5w-40. GM used the 0w-40 to eeeek out MPG to meet EPA standards (because it reduces engine drag). At any rate, dry starts from A/SS events can't be beneficial in this regard.

Not here to argue with you, take your argument to congress who is changing it. 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. Until there is a change keep pushing one (1) for english.

They know what is good for us......🙃

ASS is another one of those E85 boondoggle's........a big joke.

 

[BigMick23]

I installed the AutoStop module in my 2026 ZR2 this morning and it works as advertised........
I will monitor it for a few weeks as I put on some miles and make sure it continues to work and shut off the ASS system when the vehicle is started.
Simple installation, tricky part is getting the tool on the connector in a confined space........otherwise pretty simple.

I'm happy, but too bad we need to spend $$ to disable something forced upon us.

ASS Connector.

ASS connector with pin released

Proper placement of connector removal tool......

This is what burns my ass the most, more than the individual annoyances that come from it, and it goes far beyond vehicle regulations and mandates. Some bureaucrat decides that everybody needs some technology or assistance or some other bullshit, so it’s forced on everybody, and then far too many people end up being dependent on it, or convinced it’s best for everybody. It’s destroying society. There, I said it. Bombastic hyperbole? I don’t think so, but I’m just an out-of-touch old fart, so what do I know. Now all you little a$$holes get off my lawn.
