It is part of the engine I do know what exactly it is the VTC and diagnosed through Honda at their Golden, Colorado location. Other car makes and models from them have recalls with these exact issues except mine but it is the exact same issue. This has been an ongoing issue since I bought the car back in 2017 but the car was finally able to consistently make the noise enough to be diagnosed.

VTC actuator grinding noise during cold starts. Dealerships said it’s not a problem.

When attempting to start the vehicle, especially on cold mornings, I hear a grinding/rattling noise almost like a grinding clink. I think there is a problem with the starter similar to recalls for other Honda models.
