Battery Dead

[IronMan]

That’s interesting. I never have the key card in there. I took it out as soon as I got the truck home.
I find it very odd that it is so low.
It reminds me of something I had in my wife’s infinity. The voltage was always around that 13 to 13.5. Infinity has something that shuts the alternator off a couple minutes after starting and will turn on at certain times while you’re driving. Supposedly it’s supposed to help with the fuel economy, but it kills batteries like crazy. It’s a pretty known issue for infinity. Wonder if it’s something similar in these trucks.

i never thought to look into it but my wife's infiniti has done the same thing..... QX80 we've had almost 8 years and on the 3rd or 4th battery..... my FX35 we've had longer and I think I've replaced the battery once in it....

There’s some videos of people cutting a wire under the hood for the Infiniti to bypass that system and it makes the alternator function like a normal alternator. We did it on our qx80 and have not had an issue since then.
