The battery in the car is getting older, but it still cranks the car over. Could ever so slightly low voltage be causing this?

I hate annoying idiot lights. Owners manual says take it to the dealership; no other explanation, which is BS. I'm not going there to get shafted out of hundreds of dollars unless I understand what's truly wrong.

If you still have the OEM battery in the car, replace it and see if that solves your problem. You live in AZ, so the heat is going to play havoc with the battery, along with the antenna under the console.

Battery is an AGM that was put in the car in early 2017, but AZ does kill batteries.....it is kept in the garage full time.

It could still be weak.

What does the heat have to do with the antenna?

The main antenna is under the console, it's in an area that gets warm from heat reflected up from the road and transmission. I put a piece of aluminum foil (shiny side down) on my 2012 and didn't have a problem with reception. I made sure it was under all the wires and such.

My 2015 stays inside the garage on a tender when I don't drive it. If you have a tender, try putting it on the car over night and see what the key light does. Electronics can be weird sometimes, even more so in cars. GL

I have two fobs, one works fine the other doesn`t work at all even with a new battery, do they need to be re-programmed occasionally

Not that I've ever seen. I have seen the contacts on the pads wear out or become clogged with debris (skin oil, dead skin, etc). It is possible that is what's happening on the one that doesn't work, it might be water damaged. The only way to know it there is water damage is to open it. There's a DIY on here that tells how to open the case.
