General Motors on Thursday said it is recalling about 109,000 vehicles due to two concerns that could cause the rear axle to lock and the passenger-side airbag not to work.

The carmaker said that the airbag recall affects almost 96,000 of 2005 to 2007 model year versions of the Cadillac CTS.

The axle recall affects almost 1,300 of 2011 model year versions of the Cadillac Escalade, Chevrolet Avalanche 1500 and Silverado 1500, as well as the GMC Sierra 1500.

Dealers will replace the passenger presence system in affected vehicles at no charge to the customer.  The axle recall is expected to begin in January. GM did not say when the airbag recall would begin.
