Unknown or other
The glass on the panoramic sunroof exploded/shattered under normal driving conditions. It was raining but not too heavy. It didnât appear that anything hit the glass and no potholes were hit. It seemed to be due to pressure or temperature which caused the explosion which sounded like a loud gunshot and the glass was in pieces. There were no injuries as the sunroof shade was closed and thus the glass fell on the shade. It has not been inspected by dealership or insurance as closed on Sunday and today due to Labor Day, but yes it is available for inspection upon request. However, as it was raining and I needed to get home, I covered the entire sunroof with Duct Tape.

Visibility/wiper
- windshield, and I had Satellite repair it through an insurance claim because it was urgent for my safety. - the windshield and its adhesive never bonded together making the windshield structurally unsafe and if I would have gotten into an accident then my vehicles airbags would have not deployed properly. - The issue was brought to my attention from a Satellite repair representative. - yes Safelite who contacted my insurance. - I went through a car wash and found water making its way into my car interior, which I then inspected and found that my windshield was floppy and not attached to my car and how it should.

Wheels
5 MONTHS AFTER RECIEVEING THE CAR I WAS ON THE HIGHWAY AND MY FRONT PASSANGER SIDE TIRE AIR PRESUURE INDICATOR WENT OFF. I PULLED OFF THE HIGHWAY AND PUT A "FIX A FLAT" IN THE TIRE THINKING I RAN OVER A NAIL. THE TIRE WENT LOW AGAIN SO I DROVE TO THE LOCAL MERCEDES BENZ DEALERSHIP WHERE THEY MOUNTED THE CAR AND SHOWED ME THE "FIX A FLAT" GEL COMING OUT OF THE SIDE OF THE UNDAMAGED TIRE INDICATING A CRACKED WHEEL. THEY REMOVED THE TIRE AND INFACT I HAD A CRACKED WHEEL. 4 MONTHS LATER MY FRONT DRIVERS SIDE AIR PRESSURE INDICATOR WENT OFF WHERE THE MERDCEDES DEALERSHIP CONFIRMED MY SECOND CRACKED WHEEL IN LESS THAN A YEARS TIME!

Desiccated Air Bag Inflator RuptureOpen
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled…
