2015 Prius C - trouble starting

I thought the Three trim used a pushbutton start system? Or perhaps that wasn't true until a later model year?

Can you clarify whether yours has a traditional ignition lock on the side of the steering wheel, or a pushbutton starter?

 

Then my first guess is a dirty or failing contact in the actual ignition switch there on the steering column.

It sounds like the increase in incidence may soon make it easier to demonstrate at a repair shop.

 

Same issue with my car. it is 2012 pc 2. I highly doubt this is a mechanical issue with the ignition switch. More likely it can be related to not competed prep cycle. Either weak battery or ….

 

Does that model also require your foot on the brake to do a full "start" ?

Could be a sign of a weak 12 V battery too......not properly booting up some of the
electronic boards.

 

No need for foot-on-brake in our twist-key Two, but I can't speak for older model years.

Foot naturally goes on the brake about then anyway because it is needed to shift out of Park, but that's just coincidental.

 

Sounds like the 12v battery to me. Especially if it's the original. Although that 2 minute wait you describe makes me think there might be something else going on as well.

But I'm really curious how you got a trim 3 without push button start.
