Push start auto 100% does require the brake being depressed, if using my dad's Lexus as the basis...I'm certain smart key/push-start systems used are the same.

It's not a requirement for the manual either, but probably good practice.

oddly, yesterday my car wouldn't start and it took about 7 seconds of continuous nonstop cranking before it turned on... hello future engine problems?

i experienced it for the first time yesterday as well. push button start, auto transmission. i don't recall how firmly i was pressing on the brake pedal, but it took about twice as long as usual to crank before it started - maybe 5-6 seconds. this was in the afternoon, about an hour after i had driven it somewhere, so it wasn't a completely 'cold' start. never had a problem with cold start in the morning, or going home from work, when the engine has had time to cool completely in-between starts.

You know I had the same thing on my manual FR-S where it won struggle to start, happened maybe two times a week to me. When I was installing my Perrin silicone intake tube, for giggles I completely disconnected the battery terminals and ground and tightened everything back up nice and firm with a ratchet. Hasn't struggled to start since, and that was over six weeks ago in the same type of weather. I have a feeling flinging the car into a few select corners every day on the way to work probably loosened the connections causing the weak start. Maybe give that a try just to be on the sage side?

To add, I don't have to wait for anything to prime either after tightening up the connections, just turn the key immediately after putting it in and it starts right up.

Not sure why you would need to press the brake anyway to start an automatic. I assume these cars (as do all automatics except maybe cars that are antiques over 50 years old) have a 'Neutral Safety Switch' and the car will only crank when in Park or Neutral. Manual transmission cars have a 'Clutch Safety Switch' and will only crank when the clutch pedal is depressed. Are these cars any different? I'd think that pressing the brake pedal might only be a safety thing (since about half the owners manual seems to be safety bullets) that the manufacturer writes in there in the odd chance that your neutral safety switch fails and allows it to crank in reverse or drive.
