Rear Hatch open button fracture lines?

[Myjigglybelly]

Got in a rear ended yesterday during stop and go traffic on my brand new Yukon (100mi on odometer) and I noticed there are fracture lines around the hatch open button area. Could anyone confirm that they don’t have it?

Those are called witness lines. The injection mold for that part has an “insert” which they swap out of the tool to mold the version without the power liftgate. The lines show up at the edges of the insert.

Don’t worry there is nothing structurally wrong with the plastic. It’s just cosmetic.

They make a T2 with no power lift gate?

I think the panel can physically separate there to facilitate repair of the switch if necessary Vs removing the whole tailgate panel. No big deal at all….

Do you mind taking a picture of your rear hatch button area?

Looks like accident damage to me.

Well, I was wrong!

highly doubtful....if that was the case there would be a clip/bolt/screw in place to do such a thing

SLE and LS trim have a manual liftgate.

I design injection molded plastic parts for a living. These are 100% witness lines from an insert in a tool. Trust me.

our 2021 Yukon, 22 Z71 and now our 23 have had those lines in the tailgate...pictured is our 23

I guess why do they design such that the witness lines are in such a obvious place?
