General Motors announced on Friday that it is issuing four more recalls that cover a total of 105,688 cars and trucks around the world.

The new recalls has raised the total number of recalls for the automaker to 34, including one involving defective ignition switches and linked to at least 13 deaths, according to Reuters.

GM's recalls for this year so far cover about 13.9 million vehicles in the U.S., which includes the 2.6 million cars with faulty ignition switches. The company has recalled close to 15.9 million vehicles globally, and about 90,000 of the vehicles recalled on Friday were sold in the U.S.

69,552 heavy-duty Chevrolet Silverado and GMC Sierra full-size pickup trucks from model years 2014 and 2015 are covered in Friday's recall. Chevy Tahoe and Suburban, along with 2015 models of the GMC Yukon SUV, are also covered, Reuters reported.

GM said it is recalling the vehicles because the base radio may not work, which would prevent audible warnings if the key is in the ignition when the driver's door is open. Another problem is that if a front seat belt is not buckled, there would not be an audible warning.

The company added that it was not informed of any crashes or injuries related to the issue.

"In all cases, customers will receive letters from GM letting them know when they can bring their vehicles into a dealership," GM said in a statement on its website, Businessweek reported.

Failure in the airbags is the main issue in three of the four recalls, and has been a major focus for the Detroit-based automaker and other car companies. U.S. investigations and recalls due to defective airbags have also taken place in the past two years for products from Ford Motor Co., Nissan Motor Co., Honda Motor Co., Toyota Motor Co., Volvo Cars and Chrysler Group.

GM said no crashes involving airbag failure have been confirmed, Reuters reported.

The steering wheel air bag coil will be replaced by dealers. The replacement will prevent contact between the shorting bar inside the driver's airbag and the air bag terminals.
