Anyone else notice this sound?

[macgyver60]

I've had my MachE Premium extended range for 2 1/2 yrs but about 3 months ago I started to notice a sound I never noticed before. Whenever I press the accelerator or let up on it I hear a brief faint "knock" coming from the rear of the car. It sounds like the sound when one billiard ball hits another. It just lasts a second but happens every time I press the accelerator and then again when I let up. I get the same sound whether I am in 1-pedal mode or not. I removed all lose objects inside the car and no change. I've tried accelerating as minimally as possible or barely let up on the pedal so that delta-V is barely perceptible and it still happens. I don't think this is a big deal, just curious if anyone else noticed it or had any idea what it could be? Thanks

A little engine knock is not unheard of in higher mileage cars. Just use higher octane electrons when fueling and have the service department check the timing during the next service.

Wow, thanks. Sounds like that's it. I'll take it to the dealer and see what they say

I have also just started noticing a similar sound in the last couple of months. I am right at 2 years and ~44k miles ownership. Did you get it fixed?

Yes, this totally happens to me too. I notice it mostly in cold temps.
