“The sunroof locked open during a road trip. I am mechanically inclined, so adding lubricant and driving through a low pressure air front caused the sunroof to shut. Had I been in an emergency, not mechanically inclined, or if this happen during inclement weather or to a little old lady this would have been a severe issue causing the vehicle to become inoperable due to rain or snow entering the cabin and reducing visibility, and damaging the electronic components in the vehicle's cabin. …”

NHTSA complaint #11572718, filed 2024-02

“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.”
