PIP5806B

I've had well over a dozen episodes of long crank/fail to start on the 2021 Silverado1500 Duramax (2700 miles). Had 2 in one day last week. I noticed this post about possible fix today (PIP58068). I called the dealer today and was told my VIN wasn't on the bulletin. They gave me an appointment for middle of next month to diagnose. This will be the third trip for this issue. I fail to understand why my particular truck isn't on a service bulletin that calls out my exact problem with the same year and motor.

In case it's not a typo, and FWIW, it's revison 'B' of pip5806 -- so PIP5806B rather than PIP58068

Common for them to add a suffix, or a new suffix to indicate an update to a previous PIP.
The one posted includes a log of the release dates and reasons for update.

There is a copy posted by 'jay p' (thanks!) at post #250

Indicates it covers 2020 and 2021 LM2...

Had an appointment for my truck today, same as yours, ECM was up to date so that is one possibility off the list of many things that it could be...I tried to talk to the service guy about what I have been researching and reading but he said..."you're reading it on the internet sooo". He didn't want to hear it, so until GM comes out with something we are left here with the issue. I hope your appointment goes well!

Just out of curiosity but what happens if you try to start with the key fob or app?

My 2021 has less than 3,000 miles and has done this at least 6 times including once with the fob. Had it into dealership they hadn’t heard of this problem and did a flash to the computer with no results.

My 21 Silverado with the 3.0 is 5 weeks old, with 1500 miles. I have had the starter issue 3 times so far. Last week was the worst. I came out of the doctors office , stepped on the brake, pushed the starter button. I think it cranked for 30 seconds before it stopped. I feel so helpless because there's nothing I can do to stop it. I called two dealers and both said they never heard of the issue. Both were unaware of being able to pull up a trouble code on it. Both also said the same B.S. story about if we can't duplicate it, we won't fix it. I'm turning my camera video on every time now before I try starting. Hopefully I can video it. I've got an appointment to see if the tech's can pull up any codes. Dealer wanted me to leave it for a few days to see if they could duplicate it. I said NO! that's my only means of transportation. Maybe if enough of us with the issue complain, GM will do something about it. Let's keep each other informed.

I’ve been doing the same thing trying to record it. I did catch part of it with my phone when using the key fob to start it but by the time I got the recording app up I only caught about 5 seconds of it. My truck has less than 3,000 miles on it and has done it about 6 times. Had it into dealership and they flashed the computer but no result.

Have less than 3,000 miles on my 2021 and have 6 incidents including 1 with the key fob remote start. Exact same each time. Cranks fast for about 15 seconds then stops and when I try restarting, it starts right up. Dealership did a flash to the system after two incidents with no results. since I live in a smaller town I called a larger dealership two hours from me in Green Bay, Wi spoke with service and they advised they only heard vaguely about this. Funny you can find loads on a forum but the place that sells this stuff never heard of it.

 

[TexasAggie]

New here with a '21 RST, purchased in July with 2045 miles, and have the same start issue. Funny thing, I've been reading up on the 3.0 across numerous forums and read this thread recently. So wouldn't you know it, today I had my first initial no start, then subsequently start on second attempt. I was walking to my vehicle when I used the key fob for early start up, and realized after a couple of seconds it was just cranking. After the vehicle quit rolling the starter, I climbed into the truck, pushed the button and it started immediately. My only guess to the problem is i jinxed myself reading all this information. 😂

My feeling is they have heard of it and know exactly what's I'm store for them. They just say this to get away from having to spend so much time on it and not get paid for any of the services they perform. This is why they'll say things like, "We already exceeded the amount of time GM authorizes."

I sometimes wonder if this isn’t just the case of a specific potentially defective part stopping at a very specific point in its rotation or something. Many times out of many times it doesn’t stop in this position and doesn’t cause a problem, but just once in a great while it will stop in just the right place and cause a no start. That’s what would make this so random. Does any of this makes sense ? More sense than software?

 

[ronhend]

My 2021 GMC Sierra has done this 4 times in 4500 miles.
I have noticed it never has done it on a cold engine, first start of the day.
It seems to do it after the vehicle has run for a while, shut down for 45 minutes to an hour, then attempt to re-start.
Maybe the cam position sensor (service bulletin) is on to something, heat causing metal to expand increasing the gap between the sensor and pickup.?????
Took mine in yesterday to get the software updated, arrived early for my 9:15 appointment, was told they couldn't even look at it until that later in the day because so many were ahead of me.
So, I cancelled, will try to reschedule.
Oh yeah, this is the first dealership I've talk to that says they have seen a few with this problem, others always say they have never heard of it.

The way some of you guys talk about dealerships and GM just solidifies the notion makes me shake my head. While no dealership may be perfect, and there are sub standard employees in every field, I’ve been in this field for over 25 years now and can tell you that I cannot even count on one hand the times that I’ve seen a dealership service department employee blow off a customer on something like this. In this instances, it was the service department that I was working in that was on the receiving end of the customers wrath from previous dealership(s) ineptitude. Out of all of those instances, maybe 1 or 2 were actually the fault of the previous dealer(s). A lot of times, customers and dealership employees can struggle a bit to communicate properly to where the correct information is given. It’s nobody’s fault, just the way it is. I get irritated too when a doctor, dentist, etc doesn’t understand what I am trying to tell them too, for instance.

One thing that I can assure is that GM doesn’t just sweep things like this under the rug. I know some of you believe that once they’ve got your money, you’re on your own. The automotive industry has to be one of the most rigorously scrutinized and regulated industries in modern times. I’m sure they are on it. My theory is that it is a difficult software anomaly to diagnose and repair or maybe it is even an internal fault in the ecm itself. We all know how bad the supply chain is messed up for ecms right now. A lot of industry’s are struggling for supplies right now. The automotive industry is being hit hard and fighting daily to resolve it. Personally, I sure hope it doesn’t drag on much longer but at this point, all I can be is hopeful.

Stepping down off the soap box now. I apologize ahead of time for sucking up anymore bandwidth.

I took my truck in for this issue 6 weeks ago. It was the first they have heard of the issue. Since then, they have had 5 others with same issue. Initially ordered new exeter wheel for control panel as initial GM bulletin said to do this. The GM bulletin that came out on 8/16 regarding the installation of a shim between sensor and wheel is next up.

This reminds me of an old analogy I heard from a mechanic. Mechanics and doctors are similar. Doctors, however, have a person who can tell them where it hurts and what's wrong. A mechanic can't ask the vehicle those questions, so it takes more time to diagnosis and fix.

Thanks for your reply Chevytech77, I know this is a very difficult time for many working in the auto industry.
The service writer I spoke with yesterday said the reason for the long waits for service is the backlog on parts ordered. They have autos waiting for parts, when they come in they have to put them ahead of new service appointments coming in, which is understandable.
I have had several friends through the years that were either service writers or techs, I really appreciate you guys and what y'all have to deal with, not an easy job.

Our 2021 Silverado 3.0 had a first time cold no start last Sunday. Every other time the truck had been at operating temp, then parked for 15 is to 2 hours.

 

[GMC1500diesel]

I have a 2021 GMC 1500. Ive had it happen one time at about 300 miles and no more. My friend bought the same truck about 2 months earlier and hes had it happen twice now with 1800 miles. I only bought a diesel because i drove his and was really impressed. Im not sold on the shim fix because they first said the bent trugger wheel would fix it and it didnt. I will trade and get a 6.2 before i let them pull the cab on my truck.

 

[Rottmon]

My 2021 3.0 L also has the long crank and fail to start. No codes and so far has always started the second try. Have 2500 miles and has done this about a dozen times. I lodged a complaint with chevy and then was told to get the truck to dealer. Its been there for a week today with no resolve because they haven't duplicated the problem. I was told yesterday they would give it another try today then see what there boss says about it. I was also told they couldn't try any parts until they see a failure. They have no idea what might be going on.

I traded my 2013 2500HD 6.6 Chevy for the 2021 Sierra 3.0 looking for better gas mileage love the truck, but after arriving to Georgia from Florida the long crank starts started with no CODES.
Have an appointment on Monday at a GMC dealer in Gainesville GA.
Have started to look at other options just in case this doesn’t get fix, but pretty concerned on the statement posted on the web about dealers or GM not knowing how to fix the problem 🙏🙏🙏

In a notice to union members obtained by the Free Press, and confirmed by GM, the automaker will make the following production adjustments starting Monday:

• Flint Assembly, where GM builds the full-size heavy duty Chevrolet Silverado and GMC Sierra pickups, will operate on one shift for the week and is expected to resume regular production on Aug. 2.
• Fort Wayne Assembly in Indiana, where GM builds the full-size light-duty pickups, will be idled for the week, expected to resume regular production on Aug. 2.
• Silao Assembly in Mexico, which also builds full-size light-duty pickups, will idle for the week and is expected to resume regular production on Aug. 2.

"These most recent scheduling adjustments are being driven by temporary parts shortages caused by semiconductor supply constraints from international markets experiencing COVID-19-related restrictions," GM spokesman David Barnas said in a statement. "We expect it to be a near-term issue."
The news comes less than seven days after GM said it would have to idle four of its North American plants that build midsize SUVs — including Lansing Delta Township Assembly — starting July 19 and running for two weeks due to the chips shortage.

Production runs of most all automotive production facilities may never run like they use to. New vehicle supply is tight right now but auto company’s are not having to deeply discount vehicles due to over production/low demand either. Therefore, production of automotive parts/vehicles is going through a big change right now that will shape how the industry builds out from now on too.

 

[Stbentoak]

Yep, I said in other forums that paying MSRP or above in the future would become the norm and many people foo fooed it. But I think it will be controlled by production and allocation and going to a more of order what you want and wait for it instead of flooded dealer lots and 5-10k off the sticker, begging you to buy. I think those days are over on hot ticket models. Not mass produced sedans, but all truly desirable models that you can barely find anywhere anymore……also chip issues aren’t going away anytime soon, which won’t help…..
