I own a 2023 Mercedes CLA250 VIN: [XXX]. This morning I was driving 50 mph on a road with no traffic, no car in front or behind me, no trees or overhead wires and my sunroof imploded. I have the privacy screen closed which saved me from the shards of glass raining on me. I have included pictures of the roof as well of the poor quality of the glass that is used for the sunroof. I am shocked there is no safety film in that glass to prevent it from shattering. This was a terrible experience- I expected more from a Mercedes. I’m horrified this can happen.

Exploding sunroof. Dealership will not accept responsibility even though this is a known issue with their cars. This exploded on the highway and could have caused major issues for other drivers and myself with flying glass. There was not any external impact that caused the explosion. Mercedes needs to recall and fix this issue to prevent other accidents.

I slid on snow during a storm and hit head on to an oncoming car and my car has been deemed a total loss. During the crash not a single airbag at all deployed. I hit the windshield and the dash, at least one should have gone off, but none of them deployed in the car

While executing a right turn, the steering wheel became locked. The driver attempted to apply the brakes, but they were unresponsive. Consequently, the vehicle collided with the divider.

electrical 1 complaint shown

During regular use my 2023, Mercedes Cla 250, had a fault in the instrument display in which the display shut off completely. Only the media display remained on, however the media display is completely useless in this scenario, only the instrument display can show the speed in which the vehicle is traveling and the Rpm range in which the vehicle is being accelerated at. I was left stranded, hopeless, and endangered as a result of this catastrophic vehicle failure.
