I've got a 2015 Aero Coupe, which I guess is going to be the same engine and fueling set up and it always starts immediately hot or cold.
I just googled it which made the following suggestions...
Crankshaft or Camshaft Position Sensors: As these sensors age, internal thermal expansion breaks down their circuitry when hot. They fail to send precise rotational signals to the ECU until cooled or subjected to extended cranking.
Fuel Pressure Leakdown / Leaking Injectors: If an injector drips or the fuel pressure regulator bleeds off pressure into a hot intake tract, a temporary rich or vapor-locked condition occurs, delaying immediate ignition firing.
