2016 MERCEDES-BENZ GL450

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).

Air Conditioner always make musty / moldy odor. Many forums says that is a common problem all across Mercedes models and it causes allergic reaction resulting in sneezing all the time when a/c is on. Problem is especially bad for my kids who have environmental allergy like mold/mildew. This horrible odor coming from a/c is due to mold/mildew forming on condenser. Please order a recall ASAP.

1. Transmission spontaneously disengaged park to allow the car to roll backwards 10 feet. No one was in the car at the time of the incident. I have a security system video of the incident. 2. Spontaneous runaway vehicle could have crashed children in the driveway or the street. 3. The dealer is not available to reproduce the problem. 4. No one performed any inspections at this time. 5. The vehicle did not present any warnings messages or other symptoms of the problem prior to the failure. I have a security system video that shows the vehicle parked and 20 minutes latter the vehicle spontaneously moving backwards a few feet and then stops. Please contact for a copy of this video.

THE SUNROOF IN THIS VEHICLE SHATTERED OVERNIGHT WITHOUT ANY KNOWN CAUSE. THE VEHICLE WAS PARKED IN THE DRIVEWAY AT MY HOME. NO ONE WAS INJURED IN THIS INCIDENT. THE VEHICLE WAS LAST DRIVEN AT 10 P.M. ON 05/01/18 WITHOUT THE DAMAGE, AND AT 7:30 A.M. THIS MORNING, 05/02/18, WHEN I WAS GETTING READY TO LEAVE MY HOME, I NOTICED THE MIDDLE OF THE SUNROOF WAS STICKING UP A LITTLE BIT...IT LOOKED LIKE A PUNCH FROM THE INSIDE. WHEN I OPENED THE DOOR, A BIG PIECE OF THE MIDDLE OF THE SUNROOF FELL DOWN ONTO THE SCREEN UNDERNEATH IT AND THE REST OF IT WAS SHATTERED BUT STILL IN PLACE. THIS WAS THE FIRST DAY OF REALLY WARM WEATHER WE HAVE HAD IN A WHILE AND I DON'T KNOW IF THAT COULD BE RELATED TO THE CAUSE. WE TOOK THE VEHICLE TO THE MERCEDES BENZ DEALERSHIP AND THE REPRESENTATIVE THERE SAID HE HAD NEVER HEARD OF THIS HAPPENING; HOWEVER, THERE ARE MANY INCIDENTS REPORTED ON THE INTERNET OF THIS EXACT SAME ISSUE. I HOPE YOU CAN FORCE THEM TO LOOK INTO THIS ISSUE FOR SAFETY REASONS AND ALSO FOR THE MONETARY EXPENSE TO THE CONSUMER. IT SHOULD BE A WARRANTY REPAIR ITEM.
