On certain buses, the convex passenger-side exterior rearview mirror may not be curved enough. If fitted with a convex passenger-side mirror, Canadian regulations require a minimum and maximum curvature radius of the mirror surface.
Safety Risk
This small error does not affect safety, as the visibility out of the vehicle is not limited by the non-compliant mirror assembly.
Corrective Actions
This is not a recall. Nova Bus has made production changes to ensure that all new buses have compliant convex passenger-side rear-view mirrors.
