I bought the MY2017, built late 2016, Premium in fall of 2020 with about 24,000 miles on it. At some point about 1.5 years in it developed what I thought was a 'plastic-y' rattle, like what a loose electrical pigtail would sound like in the lower right front. For a long time I thought it was something in the pass/right side door, so opened up the door to check for loose panel clips, etc. Not. Thanks to a poster on this forum (Tietjens) who described a similar noise, I fixed the issue. It was a right side latch issue, within the engine compartment.

I was hopeful that this may be the cure and it was. Not sure what the infrastructure is up in that corner, but something in the linkage/cabling between the left side where the hood release is and this right front latch corner was loose. Tightening it up as shown in the post fixed it. It's now been several months, different weather conditions, temperatures, driving surfaces and it has not returned.

I routinely use a dry lube for all the hinge areas.. doors, bonnet/hood, hatch, door lock/close plates. I also replaced several of those black screw fasteners that hold down the covers in the engine compartment (cabin filter on right side, brake fluid res. on left side).

 

I have 45k on my car.

The only things that ever squeak are the seat belts rubbing on the seats (cured by applying leather conditioner) and the seat backs rubbing on the back of the car (fixed by being careful not to put seat back too far). Also get an occasional brake squeak but not often enough to be annoying.

One other thing that does happen is if the car interior is really hot it will creak slightly when car is underway until the interior cools down.

 

46,000km (28k miles) no rattles or squeaks in the warm weather
