new 2015 Fusion SE with single slight knock when pressing on gas pedal after start of car

[sferrell615]

I have had this since purchase on a 2015 Fusion SE 2.0L Ecoboost. I start the car, release the brake, the car starts moving forward, nothing wrong occurs until ~ a second after I press on the gas pedal, I can feel something moving in the gas pedal and hear a slight knocking noise. All the while, the car accelerates as expected and the knocking noise does not return.

I mentioned this to another Fusion owner who does not recall this. He said that perhaps it's from the 'prevent car rolling backward on hill' mechanism. I am OK with this if this is what is expected; however, I would like to fix it if it isn't.

I recognize that I notice things most others don't; however, I'm can't be the only person who has noticed this. Anyone?

Thanks

Scott

 

Ps. the vehicle health report says OK for everything.

 

Side question: does anyone know if the vehicle health report includes 'check engine light' error codes / messages? If not, I plan on purchasing a $20 reader online.

i test drove another 2015 fusion se 2.0 ecoboost at the dealership because they'd never heard of the problem.

 

this car also had 'the issue' so based on this i'm willing to digress that it is not in fact 'an issue' but an expectation.

 

no one could explain why; however, they came to the same conclusion as me... it only occurs after 1st starting the car when 1st stepping on the pedal when the car is in forward motion (in drive or sport mode). it does not occur later, at a stop light, nor when reversing.

 

i've driven other fusions (my dad has a 2.0 and a 1.5 non-ecoboosts).
