SO end of January 2020 I picked up a Silverado LTZ Z71 4x4. Great truck, love it so far.

 

However, about 2 days after I had it it died. Dead battery? I jumped it then took it to the dealer to be checked out. They "checked" it out. No issues, battery was fine.

 

Fast forward to today. Once again, battery dead. Took a while hooked up to my wife's car to bring it back to life. Sounded like a whole bunch of electrical noises going on while charging.

 

Finally it starts, the check engine light is now on?

 

I drove it to the store and back with no issues other than the check engine light and the radio wasn't working on the way there. Radio worked on way home.

 

Only has 4000 miles and this is my first Chevy!

 

I have a service appointment scheduled for Wednesday.

 

Any input or others who have had similar issues?

 

I'm supposed to be going camping Friday and I really don't need any issues while camping.

 

I've owned 2 Ram Big horns over the last 6 years with ZERO issues...

 

Grrr.

Make them replace the battery after they test everything else.  The battery needs to be fully charged as well, and you can't do that driving it around.  The alternator is just a maintainer, not intended to charge depleted batteries.  If you continue to have a dead battery after it has been replaced, then we know we have something else.  FYI modern vehicles don't do well sitting more than 2-3 weeks without use.  There is enough electronic crap in them now that draws power that the batteries drain quicker than ever and everything on the truck now depends on a good working battery.

I had the same issue with my 2020 Trail Boss at 900 miles.  It was a bad battery. The dealer hooked it up to a battery diagnostic machine for a 4 hour test. It came back as borderline fail.  They ran the test again for another 4 hours and it failed.  The battery was then replaced.

Just remember that even when a battery may "test" good it could still be bad.  It may show fully charged after a charge and pass the test, but because of bad internals it shorts or whatever is bad in the battery will quickly drop the battery within hours, so a battery tester may detect full voltage but may not detect the issue in the battery.

Traded my 2018 2500 Duramax due to a battery constantly discharging.

 

Dealer could not determine how to fix it.

 

It started at about 4000 miles. After having it towed from my driveway the third time, it had to go.

 

I loved that truck but had no trust it would start when I turned the key.

 

I have been researching and read somewhere that sometimes the Body Control Module, BCM, does not shut-down and it can drain the battery in 2-3 days.

 

Not sure if this was my problem, but may be worth asking for yours. Good luck!

UPDATE!

So after dealing with this issue 2 more times, my onstar actually sent a message to my dealership that i was hanging ABS issues. I scheduled an appointment and they tested my battery and it failed. So they replaced the battery and put a new negative lead wire because he said the one that was on it was very short and barely reached. The ABS issue resolved once a new battery was installed, they said they thought it was something to do with the amperage it was getting?

Let’s hope this solves my problem.

In my opinion the AC-Delco AGM batteries suck! Went through two on my 2015 Silverado and after the second I bit the bullet and bought an Optima. I've had the issue on several GM vehicles, so now I put the charger on once a month or so, and once the original batt dies, I go Optima. I have two 10 year old Redtops and they still rock and roll!

I have has the battery die (and had to be put on the flatbed) twice now in 1700 miles. The dealer is telling me I'm "not driving it enough".

 

The tow truck driver says to me "Yea I tow a lot of these 2020s and 2019s"

I have a 2020 trail boss and had the dead battery mystery about 4 weeks ago. 
yesterday when I got in it the truck had no volume on stereo and the CarPlay wouldn’t do anything while I tried to make a call. 
it sat all weekend and was a hot day here in Florida. Do you think the heat had anything to do with it or is my battery fixing to die again ?

I have the direct opposite, every delco battery surprisingly has given me well over 7 years of service, in each of my last 3 trucks. I bought a red top once from autozone and it was by a far far margin the biggest pile of junk i have ever used. Lasted me around 3 years before it crapped out on me. All the delcos by the way were replaced before failure, once i get over 7 years i fear of getting stranded. Maybe delcos changed but i didn't see any reason to switch brands after my 2014 trucks battery needed to be replaced, i can't complain about 7 years of solid service.

Did you have to jump start it?  Only asking since you mentioned a dead battery then no volume and CarPlay.

 

You have any mods?  I read some people say the dealer found that the heated seat was causing a very slight parasitic draw but only found that out after the dealer kept the vehicle over the weekend and hooked up hardware to monitor the electrical system.

So I saw the notice in GM Authority newsletter about this drain. I have a 2021 1500 LT but have not experienced this issue yet. Is it safe to say I am not affected by this?

The customer satisfaction number reference is  N212335340 but I cannot find details to tell if I need to get this fix for my truck. Any ideas where I could look it up?

The notice also says GM will contact the owner, if their truck is effected and to contact their dealer for repair.

Well trusting them to contact me I am not so sure about :) but yes plan to contact dealer to check.

    • My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.
    • Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?
    • I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions. 
    • I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that. 
    • Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
