General Motors has already recalled some 2015 Chevrolet Corvettes to check park brakes and driver air bags.

In one recall of 784 units, made in Kentucky from 20 August, 2014, to 4 September, 2014, cars may have only one of two the rear parking brake cables fully seated and engaged, resulting in the parking brake only operating on one of the rear park brake drums.

Without the parking brake working on both rear wheels, the vehicle may roll away if parked on a steep gradient and, as such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard #135, 'Light Vehicle Brake Systems'. 

A second recall covers just 89 cars made between 20 and 27 August, 2014 and involves the driver air bag. In the event of an air bag deployment, the air bag module back plate may fracture, allowing the bag to separate from the steering wheel.

An air bag that separates from the steering wheel may increase the risk of injury to the driver in the event of a crash, NHTSA said in a routine emailed notification.

Dealers will replace the driver side air bag, free of charge.
