Drove 2013 Honda Accord EX-L Sedan to pick up my kid. When came out, it wouldn't start. Foot on brake, in park, and push start button and all the dash lights flashed repeatedly, but the engine would not turn over. Other electrical seems fine - lights work, radio came on, etc. My husband jumped the battery and it started, drove right to dealer. Today, they say it is still in "diagnostics" since this morning, the battery tests fine, the car apparently started just fine. Anyone experience this? Any ideas? Sorry if I didn't post enough info, I am not a "car girl" and I am just hoping for some help.

 

First thing to check would be the battery and then the battery connections - sounds like one has been tested already. So next on the list would be the battery cables, inspect and clean all ends of both cables to be sure they are clean and tight.

For giggles I would also check the battery inside the key fob.
