13 Santa Fe starting

My 2013 Santa Fe sport 2.0t will not start. When the start button is pressed, the radio, temperature control lights go off and after about 10 seconds come back on.
There's no noise from the starter like if the it was not engaging or the engine is locked up. The engine was replaced about year ago under warranty and the starter was replaced.
I installed a new battery today. When trying to start the engine it's like a dead ground lights go off and then come back on.

 

Personally don't have enough experience working with push button start systems.
Do you wish to troubleshoot this yourself or are you bringing the vehicle to a mechanic??
If you are doing this yourself then you will need an electrical schematic of your vehicle.
Then you need to be able to determine what is right and what is not.
Mostly basic power and ground checks. And maybe a starter relay by-pass check.
Check fuses? Maybe a visual inspection to check for frayed wires?

Good luck

 

Checked fuses, relays, replaced neutral safety switch, tried starting like the owner manuals stated for brake stop lamp fuses blown.

 

You don't have a brake lamp issue.
Your dash goes out completely. Like there is no power.
I would suspect the push button start control unit.
But, first try cleaning the battery post and cable terminals.
Follow the negative cable to chassis ground and clean that point up.
This will eliminate corrosion issue.

I have had that issue during the summer. Intermittent no crank, no start.
Lights would go out when trying to crank.
Stuck in supermarket parking lot with ice cream in the bags.
Kept trying. Eventually, it started and ice cream saved.
Next day cleaned up all electrical with battery.
Started up and did not have another issue with the 2001 Elantra
