2025 Toyota Sequoia Hybrid

I'm looking for advice from anyone who has dealt with a Toyota warranty denial. I own a 2025 Toyota Sequoia that is still under warranty. I first brought it to Mountain States Toyota because the power liftgate would only partially open, beep repeatedly, and would not open or close correctly using the buttons. I also noticed the right side of the liftgate was not sitting flush. The dealership confirmed in writing that the liftgate was misaligned, would not operate correctly, and that there was a significant gap on the right side. Their inspection notes also state they found no signs of previous repairs or accident damage and even checked the Carfax, which showed no reported accidents. Before the issue was repaired, the liftgate strut/arm snapped. The dealership is now denying warranty coverage, claiming the damage was caused by an "outside force." I don't understand how that conclusion was reached when the exact problem was documented before the strut failed. To make sure I wasn't missing something, I had the vehicle inspected by an independent auto body shop. They provided a written statement saying they found no evidence of accident damage or any outside-force damage and that the failure appears to be mechanical. I also have photos of the vehicle before it went to the dealership and after it left, showing new damage that wasn't there beforehand. I've contacted Toyota Customer Care, but they told me the dealership makes the warranty determination. At this point I'm trying to understand how a documented liftgate malfunction on a vehicle still under warranty became an "outside force" claim despite the dealership's original inspection and an independent body shop's findings. Has anyone experienced something similar or had success getting a dealership or Toyota to reconsider a warranty denial? Any advice would be appreciated.

The panoramic moonroof on the 2025 Toyota Sequoia spontaneously shattered while the vehicle was stationary. Nothing hit the moonroof. Was told by the dealership that it was caused by a pressure imbalance and although this is a know issue Toyota will not cover it as corporate doesn't see it as a issue. Was lucky the screen as deployed as it caught the glass from hitting the driver.
