2016 Mercedes-benz GL-Class Complaints

Panoramic sunroof spontaneously shattered at some time between 2/4/26 and 2/5/26. Car was fine when I drove on 2/4/26 and parked at home at approximately 4:30p (still light outside). I got in car next day 2/5/26 at approximately 5:45p (when dark outside). Heard slight air/wind noise as pulled out of driveway and started driving. Looked up and saw sunroof completely shattered (but still fully attached). No glass inside car until the next day when the sun came out and glass started to fall in and create a hole in the broken glass panel. I was the only one who drove the car. Dealer viewed on 2/9/26, and provided repair estimate of $4,500.30. Still waiting on insurance to authorize repair. I have attached photos from 2/5/26 when discovered and next day 2/6/26 after hole formed and glass started falling into car (blocked by sunshade).

Tailgate sometimes opens while driving. It sometimes takes many attempts to reclose it from the outside of car. It will not reclose using the electronic button on the door. The alert comes on on the dashboard and its extremely dangerous as luggage can fall out. This happened while highway driving last week, scary. Apparently after googling this, it is common issue. The tailgate is one big gate hinged at the top so stuff can fall out.

Spontaneous shattering of anterior sunroof at highway speeds with no cars around and not near overpasses. Shattered glass rained all throughout the vehicle and passengers. Sounded like a gunshot and the glass appeared to be bowed out.
