The longer treatment of this generation of Elantra is over at the Queensland fitment note — apertures, geometry, the lot. This is a footnote to it, and it exists for one reason.
Two full sets went out in the same batch in June 2026, both for the sixth-generation Elantra, the AD. One went to Queensland under a heading that read 2017-2020. The other went to T. in New South Wales — two front panels and two rear — under a heading that read 2016-2020. Same generation, same doors, same set. These notes are a record of what was supplied rather than of anything the buyer said about it, so T. is an initial and a state here and nothing more.
Hyundai facelifted the AD in 2019 and the front of the car changed visibly. The passenger door glass did not. A facelift is usually where this sort of thing goes wrong — a reshaped quarter light, a moved mirror, and a panel that used to fit stops fitting. Not here. So both year ranges are describing the same four apertures, and both are defensible: a range printed on a listing is one person’s summary of a generation, and people draw the line in different places.
The consequence is the part worth flagging. Search for a 2016 Elantra, land on a listing that begins at 2017, and you would reasonably conclude you were not covered. You were. The generation code settles it — if the car is an AD, the set is the right set, whatever the heading says. It is listed at CarShade, under whichever of the two ranges you happen to find first.
