Possible battery problem?

[certifiedkj]

Greetings to all.

I have a 2011 model, which every now and then for the past couple of months, has been slightly hesitating to start. When this happens, the clock resets to a different time and it'll go to a different station on the radio, but not every time. Other times when I turn the truck off but keep the key in, I will hear a small noise possibly coming from the back, then the volume on the radio turns up out of no where.

Today, while at sonic drive-thru, I parked at the order booth with the truck still running. They were taking a while to answer my pressing of the button, so I turned the truck off. Once I turned it off, with the key still in, it did the thing with the volume again. To make sure it will still start, I cranked it up, which it did without hesitation. This time though, when it started right up, it beeped and displayed "0 Miles to E", which it's never done before. Before this, it displayed way more, and I know I still have plenty of gas; the needle on the gauge is still in the same position that it was before this occurred.

Has anyone experienced this before? Does this sound like a battery issue?

Thanks in advance to anyone that can assist me.

Battery or poor connections. How old is the battery?

The battery was slightly over 3 years. I resolved the problem though. I went out yesterday after making this post, and when I went to start it up it wouldn't start up at all. I popped open the hood, jiggled the positive wire and it cranked right up. The positive became loose, and found out the negative side was starting to corrode underneath. I took it to an O'reilly's and had it tested, which came back that it was bad. The alternator returned a good result. The guy told me that tightening the positive side and cleaning the negative side would probably work, but I just bought a new battery.

Thanks for your reply.
