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.
