general problems of the 2014 Mercedes Benz S550

Unknown.

At approximately 0030 Friday August 07, I was travelling 65 mph north bound on the ca215/60 freeway, there was little traffic. I heard what sounded like a gunshot, then a crincling glass sound and finally a whooshing of air I would soon see was a gaping hole where my closed panoramic sunroof use to be. I exited the freeway at the next exit and pulled into a gas station, got out of the car and upon inspecting the car found a huge hole where my panaramic sunroof use to be. I also made a video available at request.

I have had three run flat goodyear tires blow outward side walls rendering the vehicle in operable. All three occurred while driving on interstate highways within normal speeds of 70 to 75 mph. The first tire was replaced in FL in may - feft front, the second on August 9th in NJ same left front, and the third on August 12th in waterbury CT right front. All three tires had outward sidewall lateral destruction of 4 to 6 inches. The decompression was instantaneous the tires were 1, oem, and 2 and 3 replpacement for oem all same make and model goodyear. The vehicle is a mb 2014 S550 sedan with 20 inch rims. There is noi defect on any of the rims. The serial or VIN iswddugg8fb3a047390 net wgt 4,773 lbs. .

Backup lights on this car are totally useless. Dealer says no brighter bulbs are available. Dangerous situation. Backed into a mailbox and did $700. 00 in damage. Please advise what I should do.
