Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The vehicle has a panoramic sunroof and I had opened the roof while I was parked and when I started driving something popped and the front of the sunroof lifted a little causing it to it the back glass portion of the panoramic roof. I pulled over to check it out and saw the the front guides were broken/detatched. I had to find a way to force the sunroof to close. I was only going around 25 MPH when the guides gave up. If I would've been going faster, the force would have broken the back glass.”
NHTSA complaint #11320417, filed 2020-04, 58,000 miles“The panoramic sunroof does not properly seal to car, allowing the glass to detach and fall from the vehicle during operation and likely to impair the operator during use. Furthermore, without properly sealing the internal cabin is exposed to the environment (i.e. rain, snow, ect.) causing further damage to the internal safety and electrical features.”
NHTSA complaint #11418014, filed 2021-05“Panoramic sunroof pillars/rails detaching while operating vehicle. The front roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair. When operating the vehicle at a moderate speed, the sunroof continued to adjust itself on its own. Belive that there is a risk of the sunroof detaching from the stock plastic rails and that it may not be properly bonded. I do not feel comfortable usuing the Panoramic sunroof for fear of it detaching during driving conditions, putting other motorist and myself in danger.”
