2017 Civic Engine Knock

[BOJANGLES]

Has anyone had this issue. Car has 7,640 miles and recently developed this engine knock noise. This is not the tapping style noise from the fuel injectors. Very unhappy. Hoping someone can shed some light on this.

First question. What gas are you using?

Any modifications to the vehicle?

Any modifications to the vehicle?

Zero modifcations. Noise there cold or warm. Most notible at 1,000-2,500 rpm. Does not change as engine warms or cools.

Mid grade. It isn't a octane knocking.

Just take it to the dealer and get it warrantied if it's knocking

I'd take it to a dealer. The handful of people that have experienced and reported engine knock on the forum either had a modified vehicle or mechanically overreved their engine. (via a mis shift)

I also experienced this with my 2016, 2.0 manual. I never overreved, dealer checked, no mechanical overrev codes. Btw, you can only overrev a manual car not automatic. I'm pretty sure it's the VTC actuator. I was told to keep driving and that this is normal operation of the vehicle. However, the knock is there (once the engine warms up) and wasn't there before... it's very slight, but still there. Was told to come back if it gets louder. I've had some bad luck with this car. The funny thing is, I got a dealer rental for the day that my car was in the shop, a 2018 automatic with a few thousand on it, and while extremely slight, I heard the knock also.

I know that many people will think we are nuts here, or dreaming this up, but there is some sort of a mechanical issue that has to be developing and more cars will start having it I'm thinking.

What did they say?

What did they say?

Checked valve adjustment. Valves were loose so they did a valve adjust. Noise still there. Determined knock sound coming from within cylinder head so they are replacing the cylinder head. Waiting are parts to arrive and car to be completed. Dealership has been great. Very professional. I'll post more when vehicle is finished.
