Auto-Stop Has Come Back!

[Wiggums]

I lost this feature when it had around 800kms. I just did a very long 1,700 km drive to Hermosillo from Tijuana.

When I arrived in Hermosillo after an 870km drive (570 miles), the auto stop feature never kicked in. I arrived at night so the A/C was off.

 

Just got back in Tijuana and my truck surprised me for the first time with a green circled A and I didn't have A/C on at that time either because it was 7 a.m.

The past 5,000 kms were all city miles, few highways, I guess it just had to catch up with highway miles to make it work?

Auto stop didn't work with the A/C in other settings than Max?

When I first got it, I noticed it was less likely to kick in whenever the A/C was on, but I never used the Max in my A/C. I had to go out and look for it, didn't even know I had that, but I know I never used it.

I never had the need to defog my window so it's always off. It was only just now when I noticed the auto-start kicking in.

I always make sure everything is off so I know I never accidentally turned it on or anything like that. The auto-stop never kicked in over the past two years, I even thought it probably didn't come with that feature after the update.

Don't know if any of these apply, but lots of things can prevent auto stop/start.

 

 

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.

I can assure you none of that applies. It never kicked in since I had it when it was pretty new until just now. This is why it surprised me. I've taken long drives. The climate in Dana Point is always nice and cool, not hot or cold. I don't disconnect batteries. I don't keep my foot on the gas. I always put it in "D" when I am driving. No steep hills during my drives to L.A.

I'm going to guess based on your location that your A/C was cranking in the heat and until you reached the thermostat auto level (or if it was just set on some fan setting) that your engine was needed to keep the air coming and auto-stop wouldn't kick in.

It's cold here in Dana Point, I don't even think it ever went above 73 in the past three weeks even in the daytime. Initially, it didn't kick in whenever I had the A/C on, but then it never kicked in, with or without the A/C running, summer, winter, cold start, hot start, 50-mile drives to Los Angeles, it never kicked in. Then it suddenly kicked in after a long 500-mile drive back to Tijuana.

And I never use the thermostat at the auto-level, I always have it either LO or off, usually with A/C off. I had it off driving towards Hermosillo because it wasn't that warm at nighttime and I was trying to maximize my gas mileage, did not want to stop anywhere between Tijuana and Hermosillo. Oddly, it never kicked in after stopping in Hermosillo.

I have the same thing going on.

since about a month after I purchased my truck in Aug 2020, Auto-stop has never engaged again. It has been 10 months since an auto-stop incident.

 

I hope GM didn't catch on to something and start pushing out updates to make it work again.

I think it was just the really long drive that did it because I usually keep it parked for weeks and weeks at times. Sometimes I don't drive it for a month. But it doesn't seem to be having issues with the battery, not that I can see. It didn't kick in after the long 500-mile drive to Hermosillo.. only on the way back to Tijuana.. and it didn't even kick in until about an hour in Tijuana (despite the stop and go traffic). It doesn't bother me but caught me off guard. I totally forgot about this.

I did get an update pushed the other week...

 

PS running on LO is going to crank your AC, so again I'm guessing your AC was needing the engine on. idk...

Not when it's 68 here in Dana Point, it hasn't gone above 75 the past month. For the most part, I keep the A/C off because I don't even need it.

Okay, just did a 30-mile drive with the A/C off the whole time (no fan at all) since it was cold here in the morning. It never kicked in after I got off the freeway and came up to a stop light, hit the brakes then pressed it harder. Nope. I never saw the green circle with "A" in it again. I don't think it's coming back.
