GLC300

  • 23,000 miles
Exploding panoramic sunroof: While driving about 40mph on route 35south (middletown, NJ) in 30 degree weather at 7:30pm on 5feb2018 the forward panel of the panoramic sunroof exploded. There were no other cars around me. It was a loud pop explosion. The safety glass looks pushed out and glass started to fly behind the car onto the road. I pulled onto the shoulder and I contacted Mercedes help line for assistance. They told me to take the car to the nearest dealer (my local dealer contemporary motors in little silver, NJ). I did a night drop box drop off. Mercedes is now accessing the roof.
