Is not having a radio in a new car considered a quality issue

It is not considered a quality issue. This is because, during the manufacturing and sales process of automobiles, vehicles are equipped with equipment and configurations that are usually optional or customizable rather than required standard features, and the absence of a radio in a vehicle is not a quality issue when the vehicle manufacturer lists the radio as an optional accessory at the time of sale or when it is not included in the standard equipment items. The radio is now considered one of the standard features of a vehicle's interior equipment because it is an essential source of entertainment and information for drivers and passengers.
