One day after releasing an internal report that found a pattern of "incompetence and neglect" within the company, General Motors announced four more recalls that affect 89,126 vehicles.

One of the recalls affects 31,520 vehicles that may contain a defect that could prevent airbags from deploying in a car accident. GM said it was aware of at least one crash in which a vehicle occupant sustained an injury because the airbags didn't deploy when they should have.

The company said it was aware of other crashes that were similar in nature, but it is not yet known whether they're related to the condition, in which the shorting bar inside the driver's airbag may occasionally contact the airbag terminals. If the car and terminals are touching each other in a crash, the bags will not deploy.

Vehicles from the 2012 model year are affected by the problem, and they include the Buick Verano,Chevrolet Camaro, Cruze and Sonic. GM has conducted two previous recalls for this condition involving 7,116 cars.

GM is also recalling 57,512 models of the 2014 Chevrolet Silverado 1500, 2014 GMC Sierra 1500 and 2015 Silverado HD, Tahoe and Surburan, as well as the 2015 GMC Sierra HD, Yukon and Yukon XL models because their radio control modules may not work, and thus prevent certain audible safety warnings.

Certain models of the 2013-2014 Chevrolet Spark and 2013 Buick Encore are being recalled for a different airbag problem, which could prevent airbags from deploying properly during a crash. And 33 2014 Chevrolet Corvettes are being recalled for yet another airbag problem, in which an internal short circuit could disable the airbags.

So far in 2014, General Motors has issued 34 separate recalls that affect approximately 15.9 million vehicles – more than the company has sold in the past five years combined
