Default Battery malfunction??

So my 2011 RX has always had a sensitive battery even after changing them. I can leave the lights on or whatever without it draining the battery. But where I live is pretty hot so this morning my car battery wouldn’t start my car. Well as I was leaving work, I put my car in reverse and all of a sudden, my car went nuts and the power steering went out. Even when I got home, same thing. Any body know what’s going on?

Could be the battery if possible have it load tested. A failing battery will make the cars electronics go haywire, same can happen if the terminals are not tight and clean.

I am having a hard time comprehending your statements [it is late for me].

This may not be the issue faced by you .... Auto trans vehicles have a PRND switch attached to the shifter/transmission. PRND switch ends up displaying the gear position in the cluster as well as act as a safety switch to enable the starter in P or N position only.

How old is the battery? Our batteries rarely last beyond 3 years here in the high desert.

If your battery is behaving like that and only a year old,
you may just have a bad battery. But if this is repetitive, check your alternator and consider looking for a parasitic drain.
