    2020 pushbutton getting charging system error message when trying to start. Got a new battery, same thing. Tried the other key fob as well. Checked all fuses. Any other idea besides starter issues? It has been starting fine until this.
    Thank you.

    I assume engine not turning over, when trying to start? Are battery terminals clean, and tight? If get extended warranty, call dealer and have them check your 2020 Tacoma out. If not, contact indepedant shop for help.

    Did you check the alternator and see if it’s charging. Also what is the voltage in the battery

    try shifting into neutral to start. i wonder if the shift interlock is causing issues.

    if i shift too fast between reverse to drive while backing away, sometimes it will stall the motor, and i get all sorts of 'charging' errors, despite me knowing the generation of why they happened.

    this truck just generally seems to throw a charging error whenever it should be running but isn't, so i would label that a secondary symptom to a non-starting problem.

    LS1 swap with nitros.
    When you push. The button does it click click click really fast (like a machine gun) or just sit there like a bump on a log?

    if it clicks, then likely still a low battery. If nothing, then something is preventing it from trying to start, such as the aforementioned neutral switch.

    Same thing happened to me on my 2016 TRD OR. Dealership said it was bad battery and replaced it. This fix lasted less than one day then same charging error flashed. Dealership then replaced alternator and issued never arose again. My truck was less than 4 months old when this occurred.
