Hi,
I have 2019 Odyssey EX-L, I was driving it in the afternoon with family, there was no indication of issue, then by evening I can’t start the car, can’t use remote either. Today, got a new battery and replaced the battery, the car still won’t start.

Any idea what could be the issue? Any link to troubleshooting tips would be helpful. Thanks in advance.

 

Does the engine turn over (crank)? Need some more info.

 

Sounds like mice or rodent eating wiring?? Do you live in the city or burbs?
Is this a crank, no start? Or just no crank?

First thing to do is to clean battery posts and cable terminals.
Check insulation near the terminals for corrosion.
Follow negative battery cable to chassis ground and clean.
Also, check engine ground strap.

After that, check voltage of battery with engine off. 12.4 volts or better.
