Hey guys,when i get in my car it says low voltage and hesitates to start but always starts and then the computer says the voltage is between 13.8 and 14.0 My concern is that one day its not going to start. Ive already had the battery checked and just bought my car 2 months ago so i have a warranty for another month. Any of you had the same problem or something like it??

 

From my archives......

You may have a loose ground somewhere. There is also one very large engine ground down next to the starter. That one has a tendancy to come loose and or get corroded. Also make sure that the wires, plugs and connections on the alternator are clean and tight.

It may just be a corroded terminal or a bad or loose ground. Doesn't sound like anything major, and sounds like the alternator is working fine.
Did you have the battery load tested?
Really the only way you can tell if your battery is indeed bad. Fully charge it, than have it load tested.
