Re: 2014 V6 occasional hard start
When you start the car, do you just hold the start button until it starts?
You could try pressing the start button twice until it is in ACC mode, but not start the engine. Once the gauges have cycled and the beeps stop, you can press start again to start the car. This allows the fuel system to pressurize before cranking the engine.
If you symptom goes away, it could indicate that your fuel system is bleeding down more than normal, perhaps a problem with the fuel pump itself.
Of course, there is always the possibility of bad gas, so you might want to change fuel stations. Do you run regular 87 or that E85 stuff?
