2012 C250 suddently engine died, please help?
 

Hello,

I was wondering if someone could please share some thoughts or ideas on how I should approach this situation?

Car: 2012 C250 "keyless go" 30k miles

Situation: My mom was waiting at a red light, suddently the car died. She tried to start it up again but still nothing. I was not home to go check it out the situation, but my friend was able to get there to assist with the tow home.
No check engine light, no weird light, everything inside still turn on and functional. Just doesn't want to start.

Tried: reset battery, pulled the push start button to manual start the car, tried the second key but still doesn't want to start.

History of the car: No accident, no major repair history, maintenance is up to date.

What should I do?

Thank you

Update 1: engine doesn't crank, still nothing.

Bad battery

I will check that when I get home.

Isn't this suppose to be in the W204 section?

Dead battery....
