There are 1 owner-reported body & structure complaints for the 2023 Mercedes-Benz C-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
While driving at 60mph my panoramic sunroof completely shattered. Nothing at all hit the sunroof to cause it to shatter. If my sunshade cover had not been on, the glass would have fallen on me while operating my vehicle. This is not only dangerous but unacceptable. It was also a distraction that could have caused an accident. Mercedes did not make me aware of the class action lawsuit they have with the panoramic sunroofs, and I feel that was neglectful on their part. Upon inspection from a service advisor at a Mercedes Benz dealership, they told me something must have hit it (nothing hit it) and want to charge me $4,000 to fix it.
