General Motors announced on Wednesday six safety recalls on 717,950 U.S. vehicles.
None of the recalls were related to the ignition switch issues that have caused nearly 15 million recalls of GM vehicles worldwide this year. The new set of recalls brings GM's recalls worldwide this year to nearly 30 million.
Company shares were down slightly after the news.
The largest recall is for a potentially loose bolt in power adjustable front seats for several cars from model years 2010 and 2012.
Vehicles involved in the recalls announced Wednesday have been linked to two crashes, 3 injuries and no deaths, GM said.
The defective vehicles included 2011-2012 model year Chevrolet Camaro, 2010-2012 model year Chevrolet Equinox and GMC Terrain; 2011-2012 Buick Regal and LaCrosse; and 2010-2012 Cadillac SRX models for a loose bolt in the power height front seat adjuster that has caused injuries.
The recall also covered recent model years, with concerns of an incomplete weld on a seat hoot bracket in model year 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.
In a statement, GM told vehicle owners to bring affected models to dealers for inspection and that less than 1 percent of welds would likely need replacement.
Buick Regals from 2011-2013 and model year 2013 Chevrolet Malibus faced recalls for failure to alert the driver to burnout of one of two bulbs in a front turn signal.
Owners of 2014 Chevrolet Impalas with belt-drive electric power steering should also have their dealers inspect and repair the system if necessary, GM said, as paint may have impaired steering control by seeping behind the ground nut.
The car maker also recalled 2014-2015 Chevrolet Sparks imported from Korea for a lower control arm bolt that was "not fastened to specification." Although GM did not know of any accidents related to the issue, the company said the defect could cause mechanical problems that would result in loss of steering control.
Twenty-two vehicles of model year 2015 Chevrolet Tahoe/Suburban and GMC Yukon/Yukon Denali have roof carriers possibly attached with the wrong screws that could cause holes or tears in deployed roof rail air bags, the release said. GM added that the eight vehicles still at dealers will be repaired before sale.
