NHTSA Complaint #11454305 — 2016 MERCEDES-BENZ CLA250

The panoramic sunroof failed to close after it was opened. I attempted to close the sunroof after use and it stayed open. This is concerning as debris could have flown into the car and impaired operation. Another concern is the short-circuiting/fire risk of the internal wiring and components in the event of rain. We took the car to the dealership where an associate told us that this is a common problem with CLA class cars. This was the only inspection of the car thus far. There were no messages or warnings prior to the failure.
