    2014 Prius hybrid with about 120k miles. When I go to start it, the car dash lights up fine but the engine doesn't start sometimes. You have to keep trying the start button and it eventually starts. I checked the 12v and it's performing fine. Not getting any dash lights, and nothing seems off under the hood. Just got the oil changed a couple of weeks ago. I thought it might be the key, so I changed the battery and it's still happening. I thought maybe the car wasn't detecting the key, so I tried using the spare key and still having issues.

    Any ideas on what it might be?

    when it won't start, is the ready light on? if not, check the brake light switch

    Of course the engine does not immediately start. You want a Ready. Are you saying the engine eventually turns over for ten seconds but does not run?

    Two things:
    I have noticed with all of the Prii my family has owned, that I sometimes hit the start button without first looking for the "ready" symbol on the dash.......and sometimes that takes a few seconds.
    So, first just be sure that you aren't getting in too big of a hurry.

    Then, how exactly did you "check" the 12 V to know that it is "performing fine" ??
