Update on my 2020 trailboss I bought 5 months ago.  Failed to start right after I bought it and they replaced the fuel pump module.  It now happened again 5 months later.  The first time 275 miles on it and now 13000 on it.

I have the same issue, started yesterday on my 2020 Denali 1500 with the 6.2. I purchased the truck new the end of April and it currently has 4900 miles on it. Crank and crank with no start. I did eve

A video of it not starting is of no use to the dealer or GM. It's not that they don't believe you but they cannot duplicate the concern. Watching it not start isn't any help diagnosing the issue.

True, but if you have a video with indisputable proof that the error is occurring, it will at least leverage them to take you more seriously and give more time to do tests needed to try and replicate

I am so glad I found this thread and so disappointed that so many people are having the same issue. I have a 2020 Silverado LT Z71. The third day after purchasing the truck it wouldn’t start, all the same symptoms as everyone else. I was told it was the fuel control module. The dealer picked my truck up, replaced it and it drove fine for about 3 months. Then it wouldn’t start again. Dealer had it for a week and couldn’t find the issue. I was able to take videos that showed low voltage and check engine lights although they weren’t on at the dealer. They gave me the truck back and about a week later it didn’t start again. They had my truck for about 2 weeks and finally said they received the ecm bulletin. They replaced it and today after getting gas the truck took a while to start, but did not crank like the usual problems. So I began looking around and found this forum. I am expecting another issue soon. I have filed cases each time with GM since the first problem and am currently dealing with them now, they have no answers and so far I do not have high hopes. I will be following this thread to see what others report back with.

They are replacing the ECM in mine now. 

Interesting.....

 

I read several pages here and it seems mine was the same as the OP's.  I had JUST washed the truck that day and the GM floor mat was nudging the gas pedal just enough to cause a crank/no start condition

Seeing a pattern here.  Same issue with my 2020 6.2l wit 4,700 miles.  After sitting for 1/2 hour it finally started and I drove it straight to the dealer.  (then walked 5 miles home; vallet service cancelled because of Covid)  Check engine light came on.  Will report the outcome.

 

Interesting note after reading these posts.  The fuel pump always activated when I opened the drivers door in the morning.  It didn't do that this time.  Always wondered what was going on.  Figured it pressurized the fuel.

My dealer is saying the problem may be the aftermarket dealer installed alarm.....Karr security system. 

They removed the alarm, 3 stops later it did it again... it will be back in on Monday.

November 2020, GM posted a service bulletin for this; PIP 57335F.  The fix is to replace the ECM (Electronic Control Module), so that is what they are going to do.  Will let you all know how effective it is.

Has anyone had the ECM replaced? Did it solve the problem?

In June they replaced my ECM and fuel sender when this was an emerging issue. It worked for me. No issues so far!

I don’t think the 3.0 is listed on that bulletin, but I’ll push for it. Thanks for the info!

Happen to have any more specific info on this service bulletin?

Welcome to more goodies in vehicles = more problems.  Sorry you have to deal with it, but yes, all these newer modern vehicles are not meant to be occasional grocery getters and no other use.  I'd recommend having a battery tender installed.  Plug it in at home, unplug when you need it 5 days later, and so on.  Also invest in a good jump pack. 
I have a Corvette. It sits all winter and is only a toy for occasional use. Yes it sits long enough to need a battery tender. But if it sits a week or 2 it doesn't need it. It has all the same goodies on it. It always starts. Not being a daily driver on a modern loaded vehicle is not the problem.

Sure it is... Don't believe me?  GO visit the other manufacturer forums.  Having the same issues.  Too many goodies and computers being run even when the vehicle is off.

Sitting and draining the battery is a different issue.  This is identified as “cranks but doesn’t start” and that’s the title of the bulletin.  Plenty of power in the battery but it is as if it isn’t getting fuel.  In regard to the occasionally driven cars, even the factory alarm and those other goodies will drain the battery in time.

      Aftermath of Repair of Leaking Brake Line

      By unit731 · Posted

      Thanks for response. Leak was right under drivers seat or thereabout.   Had checked by other mechanics and have read other information.   The solution can be a tad complicated and replacing multiple parts And with some.  The issue was still the same.   The brakes do work.   Just that the pedal is softer and goes further down.  But the brakes do work.

      Breaking News!    I'm going to tell you that I'm going to tell you.  Then I'm going to tell you what I'm going to tell you.  Then I'm going to tell you.  Then I'm going to tell you what I told  you.  Then I'm going to tell you what I'm about to tell you on the other side of the break.  Then we're going to break. Then I'm not going to tell you what I told you I was going to tell you.  But I'll tell you something else that is Breaking News just coming to the desk that everyone reported on yesterday.  Then I'll tease a human interest telling I'll get to on the other side of a larger break. Then I'll tell you one item in 20 seconds and go back to an even longer break. Longest break of the night.  Then I'll tell you a fluff piece that takes 10 seconds and sign off into a three minute break while you wait for the next 30 minutes of rinse and repeat on the local news.    In al you'll get about 12 minutes of something, 5 minutes of which is worth hearing in a 30 minute show and 18 minutes of advertising at a sound level twice as loud as the news.    Of course you can switch to cable news and hear 12 different people tell the same four stories in much the same format as the Network News for 20 hours of which the majority will be advertising.  And four hours of late night Specials about things you wonder why you stayed up to listen to. Half of which will be repeats.....   OR you can go for a drive

      Audio Dampening and quiet

      By Afennell19 · Posted

      Did you ever figure this out? My 2022 Trail Boss, and now my 2026 LT did this from time to time.  I believe it was more connected to Android Auto and my phone being the cause. Maybe try going for a drive, sans cell phone.... and see if it happens?

      2026 Sierra 1500 Denali - Sound upgrade?

      By Afennell19 · Posted

      I have a 2026 Silverado LT, the non bose as well.  Upgrading the door speakers is pretty straightforward. You could honestly go to walmart, or Auto Zone/ O Reilly and get a set of 6x9s for the front, and 6.5s for the rear. You do also have to get some adapters for each, but they are like $10 a pair on Amazon. Then some plug and play harnesses that are about $10 a pair on Amazon as well.  And I would also suggest a 10 pack of the Amazon Basics sound deadening. Slap that all around the speakers and on the open metal of the inside of the door. And your golden.   I am currently doing this with my Silverado. Although I am having a bit of trouble because I am snooby I guess and bought some Alpine S2 S69c's which are 2 way components and I am having to wire from the door up to the dash....  Having never installed speakers before, its taking me just a bit to get everything correct. But if you dont buy expensive component speakers, and just some $40-$50 door speakers. You will DRASTICALLY improve the sound over these stock paper cone junk speakers. I thought my Silverado had an issue with the radio/ sound for a while.  Come to find out.  The stock speakers are just THAT SH*TTY   I cannot wait to have some decent sound in the truck   What did you end up doing?

      Parking Brake - Automatic Engagement Questions

      By newdude · Posted

      Its all automatic based on yaw sensor data.  If enough incline is detected, it engages.   My recommendation though would be to disengage it before driving off and not let it auto disengage by touching the gas pedal.  The HD trucks use the same setup as prior years, the drum in hat park brake.  But now with an electric actuator.  If you drive off repeatedly over time, it can torque the park brake shoes and can also prematurely wear them out.           Electric console shift will set the park brake on flat ground too.  Pretty sure they've got it programmed to activate every time.
