I am going to try that today and see if it works. 

I tried all sorts of pressure, harder braking, etc., still didn't work.

I don't think I have heard of this one before.  While I understand the truck should behave as expected (and this might be WAD still) the auto-stop isn't saving you much at all.   That said,

Sorry that didn’t work. The last thing I can think of is take the truck to autozone, o’reilly or some place where they can check your battery and charging system. If the battery is bad or the alternator is not charging properly then that could also cause the auto start and stop not to work. I am going based off of the experience I had with my Malibu. The alternator was bad, it would charge my battery intermittently. I don’t know how long that went on for but that caused both of my batteries to go bad (the Malibu had 2 batteries). That happened twice in 1 year. I don’t have to worry about that now since my truck didn’t come with it. I wish you good luck in trying to get this solved.

Well, I have posted before about the ever present issue of the auto stop feature not working, I know many here don't care for the feature, but with our gasoline over $4 a gallon now, it's important to me).  The last time it was in the dealership was on the phone with the factory, and once again I was told it was fixed.....I drove home (12 miles) from the dealership, took the freeway to get it good and warm, turned off all the climate controls (even though I think I should be able to use them) went to a stop light and....nothing!  This was the 4th time I had it in to get this feature fixed, each time they tell it's fixed and the first opportunity to use it nothing happens.  I also had an issue with my infotainment screen going blank and popping up with a "No Content Found" error, they did a firmware update and it worked fine until  last week when I noticed that when I opened the driver side door after shutting the engine down, the radio would keep on playing for several seconds and then it would shut down.  It never did that before it used to stop as soon as I would open the door.  Then on Friday I was stopped at a light and the infotainment system went blank, no sound no display it lasted about 15 seconds then came back on.  Anyhow, I have decided to pursue the lemon law on this truck (I have contacted a lemon law attorney), as this is absolutely ridiculous for a truck with still under 2000 miles on the odometer.  I don't know if the problems are as a result of the trucks being built in Mexico, but I am tired of it being in the service department for weeks at a time and the problems don't get fixed.

So....  Just how much power does GM have with access to our vehicles ??

I reported my Auto Stop non-functional about 5 months ago, it's been into the dealer twice, both times they said it was working, and ta-da, it never worked...

I messaged GM on Twitter, spoke to someone to place a complaint, they asked a bunch of info from me,  then, this afternoon, out of the blue, the f**king Auto Stop

started working...  I drove to work, left it for 2hrs, came back and hit the stop sign and boom, auto stop....

 

WTF ???

Well, that is the direction we are headed. But currently, these trucks can only get infotainment updates over the air. Not fixes for powertrain related things like start/stop.
 

One of the big reasons GM is introducing the Global B electronic architecture (on these trucks for 2022) is so they can OTA update these stupid little vehicle-wide software bugs (and software related recalls) without having to go to the dealer. I must have went 5 times in the first year I had this truck to get little patches done, so the new system is fine by me. If they really enjoy tracking my daily moves to McDonalds, that’s fine too. 😬

Well, I made an appointment to have it "fixed" once again.  I will have the center seat recall done as well.  I have been experiencing a fan squeak when the fan is anything above a whisper and the transmission is hesitating then slamming into gear when it's cold...and the list grows and grows.

If it's an 8-speed, the hesitation and slamming is "normal" when cold.  A remote start pre-warm will eliminate it.

LOL, my truck was built in Mexico on January 3rd. Zero actual issues (little things that i don't care to mention). 

The Auto S/S does no real improvement. Technically yes if you sit at light for over 7 seconds it will save you that tiny amount of fuel. If you sit at a light for less than 7 seconds its actually burning more fuel. 

 

I would say (WITHOUT SEEING THE TRUCK), its probably a sensor that isn't connected properly. you live in San Jose, i am in Fremont. i have a MP808 scan tool. I might be able to find the problem, but i would doubt i could find anything since the dealer couldn't. Possibly go to another dealer? 

I agree--GO to another dealer!! If it still can't be fixed I would make a case with GM. Having multiple electrical issues at the same times spells more issues down the road!!

I got the truck back yesterday, they performed the 5th recall and looked at  my concern on the infotainment which they were able to duplicate.  They state that they performed a "USB" file transfer of a new software download and afterward could not duplicate the problem and the radio  turns off immediately upon opening the door, time will tell if that solved the blanking out of the screen randomly as well.  As for the Auto Start/Stop not working, they did a re-calibration of the feature and stated it was working.  I picked the truck in the morning and at the 2nd stoplight it worked!  Then I drove the 13 miles home and upon getting off the freeway, it WORKED at the 3 signal lights to my house.  That is the first time it worked 4 times in a row!! They felt the need to supply me with an instruction sheet from GM (Stop/Start System Description and Operation (KL9)).  Now after 6 key cycles, it has stopped working again.

The truck is back in the shop, I have decided I will just keep bringing it back until they decide to fix it.  I told the Service Advisor that they really should consider replacing the ECM or BCM whichever controls the feature instead of seeing me show up every 6 weeks.  Ha ha See what happens after I get it back tomorrow????

Sorry to hear about all the troubles.

 

I really don't enjoy the auto start/stop feature, but I agree, it should work. Makes me wonder if there isn't an undiagnosed issue like a parasitic drain (do you have any non-factory accessories?) that could be pulling down the battery voltage to charging territory and keeping the "ass" (that's my acronym for it) from working. One thing you could try without taking it to the dealer is leaving the truck plugged into to a battery tender overnight. In the morning it should be fully charged. If auto start/stop is working with the battery fully charged then quits working after a few days, that might shed light on the issue.

 

You are correct, though, under warranty this is the dealer's issue and they should be figuring it out. The back/forth has the unfortunate effect of wasting a lot of time and raising blood-pressure un-necessarily.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
