Have you checked the alternator yet?Could be the issue. Dunno enough to make a clear call. When I jump the car and take it to the store and then come back it starts up just fine for a little while. It's only when I let it sit for more than 5 or 6 days that it does this.
Do you have a Multimeter?Yes I do but I'm not good at it and I don't want to put the effort into it right now. Installing the new battery on my own was a pain in the ass.
it's the flux capacitor.It's an MDX, not a spaceship.
can you take it to an Auto Zone and have your battery and alt checked? They do it for free.Good idea. I believe they do.
It's an MDX, not a spaceship.Flux capasitor is for time travel not space ships ffs.
