General Motors announced Wednesday a massive recall of 717,950 vehicles from several models due to safety concerns.

The recent model vehicles affected by the recall include the 2014-2015 Chevrolet Silverado LD, 2014 Chevrolet Impalas and 2015 model year Chevrolet Tahoes. The issues have been linked to two crashes and three injuries. However, no vehicles listed in the recall have been linked to any deaths.

A major issue in the recall is a bolt problem with certain models' power adjustable seating. But none of the recalls involve the ignition switch faults that have led to the recall of close to 15 million GM vehicles worldwide so far this year.

In its statement on the recall, GM (NYSE:GM) provided the following information on the vehicles affected:

The 2011-2012 Chevrolet Camaro, 2010-2012 Chevrolet Equinox and GMC Terrain, 2011-2012 Buick Regal and LaCrosse and 2010-2012 Cadillac SRX U.S. models equipped with power height-adjustable seats are being recalled for possible issues with the bolts connecting the height adjustor. GM says the vehicles are safe to drive. But owners are advised not to use the power-adjusting feature until their vehicle is fixed at a dealership. This recall affects 414,333 vehicles in the U.S. 

The 2014 Chevrolet Caprice, 2014 Chevrolet SS, 2014-2015 Chevrolet Silverado LD and HD, 2013-2014 Cadillac ATS, 2014 Cadillac CTS, 2014 Cadillac ELR, 2013-2014 Buick Encore, and 2014-2015 GMC Sierra LD and HD vehicles are being recalled due to a possible problem with the welding on their seat hook brackets. According to GM, the bracket hook assembly may be incompletely welded on these vehicles. Dealers will check the vehicles to see if the welding is sufficient and will correct the connection if it is found to be incomplete. This matter affects 124,008 vehicles.

The 2011-2013 model year Buick Regal and 2013 model year Chevrolet Malibus are being recalled for a problem with the system alerting drivers if their turn signal bulbs have blown out. GM says dealers will reprogram the system to correct the problem. This concerns 120,426 vehicles.

2014 Chevrolet Impalas are being recalled for problems with the belt-drive electric power steering on some vehicles. GM says a loss of power steering can occur while driving or during the car’s start-up due to a faulty ground connection to the car’s Power Steering Control Module. Drivers are asked to take their vehicle to dealers to have it inspected, and the defect will be corrected at no charge. One crash has been linked to the problem, but no injuries or fatalities. This issue affects 57,242 vehicles.

Some 2014-2015 Chevrolet Sparks are being recalled for a problem that could cause a noise to come from the front suspension and cause a steering control to be loss. GM says dealers will check the vehicle and make sure the proper bolts are correctly tightened. This problem affects 1,919 vehicles.

The 2015 model year Chevrolet Tahoe/Suburban and GMC Yukon/Yukon Denali are being recalled due to roof carriers on the vehicles being attached incorrectly. The improper installation could cause tears in the roof rail air bags if they are deployed.

A total of eight of the vehicles are currently in dealer stock. GM says the issues will be fixed before they are sold.
