Interior Rearview Mirror problems of the 2012 Hyundai Veloster

There is one serious safety defect with this car, the side mirror adjustments (in particular the passenger's side). The dealership has not been able to properly adjust the mirror and they stated that the limited adjustable was "just how it was designed. " therefore, I would like this researched further and corrective actions taken. This car is not as safe as it should be. Specifically, when a tall, larger person has the seat set in the far back position, and sits up fairly high, the right side mirror cannot be properly adjusted, and in combination with the rear view mirrors and the left side mirror, it creates "blind spots," and, in particular, a very large "blind spot" to the right--very dangerous when changing lanes or passing!.
