Sounds like an exhaust leak, inspect the exhaust system under the vehicle. Also raise the hood, you might see or hear the problem.

Other than wondering about an exhaust leak, the other thought I have is that the two hamsters under the hood have armed themselves with automatics and are at war. But mostly I’m also guessing exhaust leak.

Just to be different, I’m going with the Hamster war theory.

Sounds to me like valve tappet noise.

Perhaps the car should only be driven on hamsterdam avenue.

Does it sound like you are driving over rumble strips in the road when this sound occurs? If so, Google “torque converter shudder”. Is the symptom consistent with that?

George, the OP made a video of the noise with the vehicle not moving, the door open and a bush right in front of the vehicle, don’t think it is the torque converter…
