2014 silverado battery drain issue
Have a 2014 silverado and I keep losing power.
Can jump in the morning will start fine all day let it
sit overnight and nothing. Checked all fuses for
parasitic drain couldn't find anything. Bought a new
battery ran fine for a week or so then same issue
occurred. Tested battery it came up bad and
showed alt was overcharging, almost 16v, sooo put
a new alt and another new battery on it worked for
2 days now the same 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???
