On my 2020, many issues were definitely assembly related. Example, and I have many, but I'm not typing out the grocerie list.
Insulation pads not hooked on and just hanging by one point in cargo area beneath side panels (out of sight).
Paint apparently touched up and dabbed brutally to cover or hide dust or other flaw, how this gets past QC is amazing.
Loose fasteners on window tract.
Omitted inclusions such as two hook and sound deadening panels.
I could go on.
It's not design, it's someone failing their duty at assy point and going through unchecked.
