UNKNOWN. While I was driving down the interstate going 75MPH the top part of my grill flew off cracking my wondshield. I pulled over and pick it up and all the plastic welded factory clips broke off. This is a seriously dangerous issue that should be recalled and covered by GMC
My 2023 Sierra has an issue with the tailgate opening at any given time while in park. The dealer denied such issue until I noted a GM recall on the tailgate switch becoming contaminated with water.
Tailgate dropped while driving on the freeway. I was towing a utility trailer at the rime and the Tailgate hit the hitch area and scratched the Tailgate. It also dropped when not towing anything. I am leary to haul anything in the back of my truck
On May 5, 2024, while driving my 2023 GMC Sierra truck on HWY 40 near Holbrook, AZ, the tailgate lowered un-commanded twice while driving. I called GMC and they told me that my vin is not included in the recall. There is a recall for this exact problem however GMC said it is only for GMCC truck built at a specific plant.
I walked from my garage to the back of my truck to the driver door a drove away. At my destination the tailgate was open and my chainsaw was sitting there. Absolutely no way I could walk past my tailgate and not see the Stihl chainsaw looking at me and drive off without closing it first. I’ve owned the truck 1 week at this point

Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsAre body and structure problems common on the 2023 GMC Sierra?
They are documented: NHTSA holds 92 owner complaints naming the body and structure on this model year (19% of everything owners filed about it), and 1 NHTSA investigation is filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.
Is there a recall for the body and structure on the 2023 GMC Sierra?
No recall campaign is filed under this heading for this model year (there are 3 filed under other headings). A bulletin is not a recall: it carries no federal duty to repair for free.
When do body and structure problems show up on the 2023 GMC Sierra?
Too few of the complaints carry an odometer reading to say. The model year's page shows the mileage curve across every system where it can.
What does NHTSA's "Structure" heading cover?
Body panels, frame, roof rails, trim and glass as fitted. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
