Won't Start

[AlxCZ]

woke up this morning, nothing starting! key fob doesn't do anything, remote start not working, got in, start/stop button not working, tried shifting from park to drive, etc., not budging, tried extra keyfob nada. brake pedal seemed stiff. Do all these things shut down if I need a jump? I guess I always thought if a battery is dead, I would still get a "clicking" sound when trying to start a car? Or atleast a turning over to some degree. What could it be

Sounds like your battery is completely dead or disconnected. I check the terminals to make sure they aren’t loose then try to jump it. Or call AAA and have them come to figure it all out.

What drained it?…anyone’s guess

That's a huge "it depends". If it's dead, it's dead, that means no power.
If it's low, depending on the vehicle and starter system, it MAY make noise.
How about using a cheap volt meter and checking the voltage at the batteries??

There's so many ways batteries can go - I've seen them measure 11 volts and still start a vehicle, and I've seen them measure 12 and drop to nothing when any load is put on them.
A fully charged battery is 12.6 volts (or a touch over)
At 12.4 it's not even half fully charged.
12.2 I'd figure on walking - but you may get lucky.

My wife had the batteries in her GC go bad - on a charger over night, disconnected charger and watched the voltage drop to 11 volts in like 30 seconds. Up to that point you could jump it or charge the batteries and it would be fine for 2 or 3 days.
Dealer said both batteries were shot. (just inside the warranty)

Turned out to be the battery, got a jump and everything came back on. Have to get used to not having certain noises or clicks that once used to make us say things like: "I know that sound" it's the battery or whatever. Someday we will just reboot our cars when something isn't working!

Do you know What killed the battery ?

Sometimes they just are bad like in the case of my wife's Jeep.
In his case he'll have to track things like time, voltage and so on and check the volt meter on the cluster or off road pages now and then when driving.

I suspect cold weather maybe? At first I thought I left the truck running overnight, seems like it is very possible to do based on the fact that sometimes I can't hear the engine running! ( I really don't think I did that though)

If it was running overnight then the alternator would have been charging the battery. So it would not have been that. And you'd have no gas either if you came out to the vehicle off.

And thus the reason for the horn honk people gripe about when exiting a vehicle with the engine running. Thank you - made my case LOL

Cold weather does mean batteries are harder to charge to begin with (it's a chemical reaction and all chemical reactions slow when temps drop) - and they do tend to discharge more in the cold - think of how batteries are rated - Cold Cranking Amps - 0 degrees.

I'd have the batteries load tested, and see what the voltages are as you drive, or when you park the truck (and turn the engine off ? )
