Beyond mechanical failures, structural issues like panoramic sunroof explosions and roof panel detachment are recurring, with multiple complaints detailing glass shattering or panels flying off at speed, creating immediate dangers to occupants and other road users. The lack of comprehensive NHTSA crash test data makes it difficult to assess overall structural integrity in a collision, but the reported structural failures are alarming.
