2014 silverado battery drain issue

I had a similar issue, gm told me it was the harness that sits on top of the battery. i went thought 2 batteries in as few weeks

I’m having similar issues as above. Was the harness not tight enough or how was that effecting the battery?

I have a 2015 same issue. what is it? I thought it might be a stuck seat button! urrghhh

I have the same problem. Has anyone identified the source of the drain.

Any updates on this? Having the same issue EXACTLY!! Got a new battery (Optima Yellow top), worked fine for a few days, then dead. Checked under the hood and my positive lead was loose, like it would come off without even trying. Tightened it and Charged it overnight with my battery tender. Next day, cranked great with no issues, thought PROBLEM SOLVED!! Well, about a week later I went to remote start my truck and the lights wouldn’t come on and engine didn’t turn over. Went out and turned the key, click click click click... same issue. Trying to see if it’s something obvious I can resolve or if it needs to go to the dealer. Thanks :)

Anyone ever figure this out)?

Standing in the parking lot of a closed Napa store, trying to figure this out.

I have a 2014 and I’m currently having the same problem. I jump it in the morning just like the rest and it’s fine but when I try agin the next morning it just clicks. Does anyone know why or what it could be?

I have found that the USBs, Cigarette lighters, plugs--all in the center stack and elsewhere are not on aux power. So, if you have something plugged into those (like I did), they will be draining your battery even after you have locked and walked away from your vehicle. I am not sure if this is the reason for the problem, but it certainly can't help. Others please share whether or not you have things plugged in that may be causing the issue, or--if not, maybe you substantiate that there may be some other issue.

Just drove a used 2014 off the lot 2 weeks ago...everything on their end checked out “fine” ...I was just driving through a parking lot and out of no where truck goes completely dead...instantly!! Nothing worked it was like I went through a f*ckin portal and lost ALL POWER.....any ideas???

2014 1500 having same issue $800 later still shutting off. Very frustrating...

I bought a new 2014 Silverado when they came out. Three months later after a long weekend and hadn’t driven in three days I went out to get in my truck and the battery was so dead it wouldn’t even unlock the doors. Finally got it jumped and took it to the dealer and they said the battery was good and wouldn’t do anything about it. They said if it happened again don’t jump it. Call them and they would send a wrecker. Couple of months later, same thing happened after a long weekend. Called and waited all day for the wrecker to finally get there. They still couldn’t find anything. After I raised hell they decided to put a new battery on it. A few months later the same thing. If it didn’t get driven every day it would not stay charged. I took it to a good local mechanic. He couldn’t find the voltage drain either. I’ve been through five batteries and finally I just started keeping a charger on it every night. That stopped the voltage drain but it’s a pain in the ass. I’ve had Chevrolets all my life. The dealer has been calling me lately wanting me to trade in on a new one. I told him I was planning on trading it on a new one but it wouldn’t be a Chevrolet. Solution: Buy a Ford.

Has anybody found a solution for this issue?

Has anyone checked the G218 grounds in dash behind speakers. Solved a few of my issues. Hope this helps... Tre928

Has anyone found answers to this? I just bought a 2014 in December and now having these issues. They tested and said battery was fine. I jump it and it will stay but overnight completely dies so I have to jump again in the morning....so frustrating. I don't want to go and buy new batteries after seeing the above comments. Help.

A poor seal on the media antenna and water was dripping from sunglasses holder. It had ran across the sill to the upper console. The dealer replaced the media antenna but the water has ruined wiring in upper console. I first noticed the screen had a slight glow and the next day battery died. If it wasn’t for the torrential rain, I would never have known it had leaked.

I had the same problem and changed my coolant sensor.
