Just an update as it's been a bit now.

Have just over 1,200 miles on it, and while it still occasionally happens, it does appear to be quieting down a bit. Originally for the first few hundred miles it was seriously loud when it occurred, though it seems to have settled down considerably. It's still noticeable, but much less so. Otherwise, still have had no seemingly related issues.

So perhaps one of the (various) electric pumps simply needs some time to loosen up a bit (and quiets down as it settles in)?

Grandpa swore the sound of his .357 got quieter over the years as well.....

When my AC is on, it's really loud in the garage. Could the battery system be calling for cooling and causing the sounds.

You can hear all kinds of things without an engine running. There is even a marketing insert that came with the 4xe. My guess are some focus groups were concerned with the sounds.

Thanks for all your follow up on this. How has your hybrid gas mileage been, and has it improved over time as this issue subsided? I've noticed my 4xe seems to hemorrhage gas when it's making this noise, so hoping it's just a temporary issue.

I have heard several exhaust clamps not tight enough. Location under the drivers seat area there is a clam that isn’t tight enough. Let me know wheat you find.

Mine sounds super loud if the engine is cold and if the a/c is on from the start. It’s like after both have warmed up, the noise calms down.

I feel like this explains the increase in rpm (and THAT associated sound) but doesn’t address/explain the “air compressor” type sound.

I've explained it in this thread and there are countless explanations online. TLDR - it's normal and common.
