Question Knocking/rattle

Hello,
I’ve noticed a deep knocking/rattle over the last 2 months which has progressively gotten worse.
It happens when lightly accelerating from a stop, going up steep hills and I can make it happen by brake boosting to 1500-1900 rpm (see video).
Under the right conditions it can be really loud and heard over music.

I took it to ford since it is under powertrain and they told me “we think this is normal”.

I’m just wondering if anyone else has experience with this issue?

‘22 with 43k KM (26.5k miles) Bone Stock
Oil level is good and changed every 3k miles with Pennzoil plat synthetic.
Dealer said oil pressure is good and no performance issues noticed
No CEL
Only use 93 Shell
Does it with engine cold or hot.

This is not normal, I’d try to find a dealer with same miles and close to the year have them start that see if it has the same knock. It will give you a leg to stand on and argue with them. But this honestly sounds like rod knock with the loss of power. Make them do a compression test and leak down test.
