Mine would come on all the time when not running ac and here and there when ac was on. Yeah I think same way but I did notice it dropped some on my mpg today when doing normal city driving errands gym etc. where the auto stop comes on at almost every light we’ll not today. See what they say Saturday since I got auto stop and infotainment issues 

They updated my radio with a usb as well. It was attempting to acquire satellite signal even though I could hear a station fine, but could not change channels, also one time the radio would not power off until I shut off the ignition. Sometimes I think there’s too much technology in these new cars. One reason why I avoided the new Ram, even though I love the interior, I just didn’t feel comfortable to buy one.

Looks like there are lots if reasons:   The climate control settings require the engine to be running to cool or heat the vehicle interior. The vehicle battery charge is low.

I disconnected my battery (positive terminal) last night for roughly a minute or so, then reconnected.  Today, start/stop did not work.  The manual states it will not function if the battery was disco

Check for a loose engine ground cable. https://gm-techlink.com/?p=12383 Sent from my Pixel 4 using Tapatalk

Auto Stops may not occur and/or Auto Starts may occur because:

 

. The climate control settings require the engine to be running to cool or heat the vehicle interior.
. The vehicle battery charge is low.
. The vehicle battery has recently been disconnected.
. Minimum vehicle speed has not been reached since the last Auto Stop.
. The accelerator pedal is pressed.
. The engine or transmission is not at the required operating temperature.
. The outside temperature is not in the required operating range.
. The vehicle is in any gear other than D (Drive).
. Tow/Haul Mode or other driver modes have been selected.
. The vehicle is on a steep hill or grade.
. The driver door has been opened or the driver seat belt has been unbuckled.
. The hood has been opened.
. The Auto Stop has reached the maximum allowed time.

Thanks for this. The service advisor said in a generic overview the auto stop needs certain perimeters but this is more helpful. I wonder why they seemed to change how this works in the Sierra. I’ve been in several different makes of cars with it and they come on everytime without fail. Even my wife’s Terrain like I said earlier.

The Terrain also has a list of conditions that will cause it not to stop.  Perhaps you've not been in it when one of the conditions was present? 

 

What year is the Terrain?  

 

Online 2019 Terrain owners manual shows the same list of conditions as the cut-and-paste from the Sierra manual that was posted above.

It’s an 18. I swear it’s shut off every single time at a stop

Several of the items on the list are easy to test.

Just FYI - If you have a tow package factory installed, and you have something connected to either of the Power Connections, Auto-Stop should not work.

Thanks.

Didn't know that one! 

(the others are straight from the list in the OM's.)

 

And it doesn't it matter if tow/haul is engaged?  

 

Might have to 'borrow' swmbo's ride and check it out.

From what I've heard from others, no.  One guy installed a 4-Pin Tester, and it disabled the Auto-Stop.

Not sure if this has already been said, but when I put on my cat-back exhaust last year, it stopped working too.  It only worked one time, but promptly came back on at a light with no changes from me.  Might be part of the operating temperature range...but I live in the MID Atlantic.  If you dont like the weather, wait 5 minutes.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      OCI, not when but why?

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.

      Engine Wear and ISO 4406   1.) Cold Starts. 2.) High Particle Count. 3.) Low operating temperature viscosity and high low temperature cranking viscosity. 4.) Depleted AW, Friction and Acid packages.  5.) High engine load.    https://me.caltexlubricants.com/en_me/home/learning/from-chevron/heavy-duty-diesel-vehicles-and-equipment/The-Importance-of-Clean-Engine-Oil-and-Its-Impact-on-Equipment-and-Business-Performance.html   High particle counts have five sources. 1.) They are manufactured within the engine. Both wear debris and amalgamation of degradation products and combustion driven soot (worse in GDI). 2.) They are ingested via intake air. Ever hear the best oil filter is a good air filter? 3.) They are entrained in the fuel. 4.) This one is insidious. They are introduced in 'fresh oil'. 5.) They are introduced during the oil change.   ISO 4406 is the test that measures and quantifies the combine effects of all of the above particle related issues. You can mitigate your way into multiples of engine life by being attentive to them all.    https://www.hyprofiltration.com/blog/is-new-oil-clean   (from the link above)    [Quote] What Is the Recommended ISO 4406 Cleanliness Code for New Oil?   A good upper limit for new oil cleanliness is 16/14/11 (ISO 4406). Typical new oil usually has ISO codes of 19/17/15 or worse, which is far too dirty for sensitive components. This can be a major cause of degradation and premature failure.
