2021 LEXUS UX200 Visibilitywiper Problems

Rear glass window is much to dark in standard oem built in tint into window. Can only see out clearly in broad day light otherwise much too dark. We have been involved in several near back up collisions even though we have a back up camera, we are used to looking back through the rear window and outside rear view mirrors. We have complained to Toyota by phone and checked for recalls. WE like the to have this rear window replaced with an oem like window with minimal tint. We have no safe options other than to trade in this SUV. The consumer stated the tint was removed and there is no longer a safety concern with the windows. However, the consumer does have concern with the vehicle having a spare tire well but no spare tire located in the vehicle.
