'11 Silverado--totally Dead, Had To Be Jumped?


Recommended Posts

Posted

I came out of work today and my truck was totally dead--no dome lights, wouldn't even make a struggling sound when starting. I know that no lights were on, my truck has a stock electronic system (no aftermarket stereo, etc) & nothing was plugged in (car charger, gps, etc). I had to have someone from work jump it and it started right up. Has anyone seen this on a new truck? I got it from the dealer brand new, it is 8 months old and has 7400 miles on it. What could it be? Just aggravated that my battery was totally dead and I can't figure out why.

Check the date on the battery. If the battery is already shot then I'd talk to the dealership to see how much they will give you for it since it obviously did not last as long as it should. I have no idea if the dealership would even do anything, but that's what I would do.

Covered under the 3 year 36000 mile bumper to bumper warranty. This may be an issue with a module PCM,BCM,TCM drawing current and pulling the battery down. Wait until i does it again and have it towed to the dealership.

Hopefully it is just a bad battery. If not, if could get ugly, as there could be some hard to detect parasitic draw. Typically AC Delco batteries are excellent - mine was still good after 4 years in hot and humid Florida, even after sitting for weeks in my garage without running the truck. Who knows, maybe GM is now using a different battery source? Lower quality batteries?

 

I had a problem with my boat (302 EFI V8 Ford) where my battery would get discharged through a defective alternator (probably bad diodes inside). I had the alternator bench tested and was told it was charging fine. Still, I could not find any current draw, so I replaced the laternator, and problem solved - no more current draw and now the battery stay charged even after several months of sitting. Before it would totally run down in a day or two.

ummm.. I think there is a conspiracy afoot.

 

 

my 2010 did the same thing today no start, no juice.. but I didn't need a jump, just disconnect and reconnect the batteries..

 

 

this morning I started it with the remote start, no problem, got in turned the key it died..

 

I thought, ok maybe I hit the last second of the 10 minute window and it died before the key cycle..

 

turned the key and it started, but the gauge cluster and radio were dead.. restarted it several times to no avail.

 

 

drove to work, called dealer to make an appointment, went to lunch everything worked, came out of the restaurant and it wouldn't start, completely dead.

 

 

went back in called AAA came back out, fired up no problem.. only now no XM radio, but everything else works.

 

 

 

pulled the battery cables on both batteries and waited about 5 min, hooked everything up and everything is back, only now my temp is stuck on 55° and Compass stuck on South.

There has to be a conspiracy. My 2010 Yukon was dead last week. Never had a problem with it, it sat for a week (normal for it to sit for a week or two at a time, never a problem) got in and nothing. No dome lights, nothing at all. Jumped it, drove it around for 30 minutes, turned it off, started it up no problem.

 

Nothing was plugged in, no lights on, nothing different from the norm.

 

Have driven it since and no problem at all.

It is a known problem, but with no precise solution. There have been "solutions" consisting of a bad ground connection, arcing on the mega fuse on the firewall, bad cells in the battery (no current draw issues just flat out bad), or poor connection of the terminals on the leads (hot and ground) at the battery. This is what I would believe was the issue with my dad's truck which had the same issues as described. We inspected the mega fuse with no problems there, cleaned and soldered all all ground leads to the block and frame, reseated the main fuse block under the hood, and after the above were done in one shot it was fine for a couple months and then it acted up again and he jiggled the positive and negative leads at the battery and things were back to normal. After some further inspection the wires appeared to have a somewhat poor crimp in the terminal so we removed the factory terminals and soldered on some replacement terminals. That was about a year ago and knock on wood it has been fine ever since.

 

So just do some searching around and you'll see it is a somewhat widespread issue over several model years.

i'd buy that except.

 

I have dual Yellow Top batteries, and upgraded all the factory wiring for my winch. so bad factory connections don't apply..

 

 

I think in the OPs case it might be true, in mine it appears to be a compooper problem...

I had a very similar problem a couple months ago with my 2010 Silverado.

 

The problem started off one morning with my truck being completely dead in my driveway; I couldn't figure out why either as I hadn't left anything on. I got a boost and drove to work with no issues whatsoever (between me letting it run in my driveway for a while to charge the battery and the actual drive to work, it had been running for 30-40 minutes). As soon as I parked the truck at work and pulled the key from the ignition, the truck died immediately. I went into the office to call my dealer and the woman I spoke to advised that I have it towed (under warranty) rather than boosting it again so as not to reset any codes that would have been thrown. I had no problem with that, but my truck was not in a position that a tow truck could not get to it so I went out to the parking lot to move it manually with a buddy from work into a place where a truck could get at it and when I opened the door the domelight came on. When I saw the light on I tried to start it and it fired up instantly.

 

I was dumbfounded.

 

I had it towed to the dealership and after keeping it overnight and not being able to recreate the problem I brought it home the next day with no solution. A couple weeks later the same thing happened again so I brought it back into the dealership and told them I didn't want it back until they had a cause and a solution. After a couple hours at the dealership and a complete electrical troubleshoot, I was told that they finally found out what was causing the problem.. apparently there was some type of rubber washer on of the terminals of the battery. This washer was causing the battery cables to temporarily lose connection, probably while driving (over bumps, starts and stops, etc), causing the battery drain. This explained the odd situation where the battery would be dead at one time and start the next since it was only temporarily losing connection (i.e. it comes off on one bump but could be bumped back on after the next).

 

In any event, this happened a couple of months ago and since they removed the rubber washer from the terminal I haven't had any problems whatsoever.

    • This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com. 
    • Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver. 
    • Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....  
    • 4 low is really nice on steep boat ramps. 
    • Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
