Sunroof glass panel exploded outward. Fabric retractable interior sunroof liner did contain all of the fragmented safety glass. No prior impact on or to the sunroof. If the interior fabric sunroof liner had been retracted, the interior of the vehicle would have been showered with the glass shards impacting the driver and all passengers. There was no warning. A loud sound similar to gunshot occurred as the sunroof failed. The vehicle was driven to a local windshield repair facility for examination. I contacted and notified Mercedes Benz USA of the incident. They have not done a follow-up as of this date. I contacted Mercedes Benz of Anchorage AK and will do a follow-up with that dealership on May 31 2022.

On day zero when I bought the car, it was raining. The new car wiper was shattering or making bumpy movements. It was not cleaning the heavy rain water or it was spotty. The Mercedes mechanic told it is a known issue and there is no permanent fix. They just changed the wiper blade and put solvent on windshield which may be good for few days/weeks and need to take the car everytime, I have this issue till I have warrantee. This is very annoying and safety issue in Houston rainy season. It can happen anytime in the middle of busy road and under rain.
