General Motors Co. ( GM ) announced three safety recalls along with a non-compliance recall, in order to resolve safety issues. The automaker informed The National Highway Traffic Safety Administration (:NHTSA) about these recalls on Jun 5, whereas customers will be informed through letters by General Motors.

The first recall is for 57,512 vehicles including Chevrolet Silverado LD and GMC Sierra LD of model year 2014 and Silverado HD, Tahoe and Suburban and GMC Sierra HD and Yukon and Yukon XL of model year 2015. General Motors recalled the vehicles due to the possibility of a malfunctioning base radio.

In addition, there may not be an audible chime even if the front seat belt is not buckled.
