While driving down the road I heard a loud explosion that sounded like a gunshot hit my read window. This caused me to jerk the car and almost hit the driving car next to me. I pulled over and realized that my sunroof had suddenly exploded and shattered onto the shade located in the ceiling.

I was so lucky nobody hit us and it took 20 minutes of trying to start it to get off of the highway to a gas station where it cut off again The dealer said it is a known problem however my vin number was included despite the fact that they know that the 2020 mercedes benz s450 has an issue that should be recalled due to the severity of the situation and safety of the public.

Had windshield breakage and replacement on 14 December 2023. On 29 January 2024, had an apparent windshield strike (pinhead size) and windshield cracked from middle to top. Within 20 minutes crack had spread all across the top of windshield. While parked crack spread down and completely across the bottom of windshield in about 30 minutes. Vehicle is now in Mercedes dealership for windshield service once again. I have been driving for 60+ years and never saw this massive of a windshield crack caused by a pinhead size strike. My belief is that either it was bad glass or installation. I have read numerous complaints regarding Mercedes glass and am concerned whether I can safely operate this vehicle. Would appreciate you looking into this issue.
