New Battery is drained

[lordathey]

It is a napa legends battery and I just got it 3 months ago. Going to try and get over there today and see what they say.

I am going with a bad battery. Was probably bad when you bought it.

Napa just tested the battery and said it was good. The new negative battery cable just arrived, so I will be replacing it either today or tomorrow.

Check the manufacturing date on your truck. 2014 trucks, both Chevy and GMC's built before December of 2013 had starters that were not sealed properly when put together allowing moisture to get into them over time. Your problem is one of the issues described that many have complained about. If so, only cure is to put a new starter on it. It starts acting up out of the blue. Just a suggestion if the cable does not cure it. GM knows about this troublesome issue. They have a bulletin out for it at their dealers.
