General Motors Co. (GM) recalled 717,950 vehicles, including some recent-model Chevrolet Camaros and Buick Regals, to repair seats, turn signals and other parts, reported Bloomberg.

The action involves six separate recalls, including 414,333 Camaros, Regals and Buick LaCrosses from model years 2011-2012 to replace a bolt for seat-height adjustments, Detroit-based GM said in a statement today. Today’s actions bring to almost 29 million the number of vehicles GM has flagged in North America this year after the company also revised downward recalls announced last month.

“These recalls signify how we’ve enhanced our approach to safety,” Jeff Boyer, GM’s vice president, of global vehicle safety, said in the statement. “We are bringing greater rigor and discipline to our analysis and decision making. If we identify an issue – large or small – that might affect the safety of our customers, we will act decisively.”

GM revised its tally for the number of vehicles recalled in a June 30 action because some cars had been double counted. About 6.6 million vehicles are affected by that recall, or about 1 million less than what was initially assessed, the company said in a statement sent by e-mail.

The biggest U.S. automaker is stepping up the pace of recalls as it faces multiple investigations for its slowness in calling back 2.59 million small cars with ignition flaws linked to at least 13 deaths. Since that action began in February, the company has recalled other cars for similar issues.

Today’s recalls also include 124,008 vehicles where seat hook brackets may have received an incomplete welding, GM said. No injuries or fatalities are related to this recall, GM said. The welding issue affects the 2014 Chevrolet Caprice, 2014 Chevrolet SS, and 2014-2015 Chevrolet Silverado LD and HD and 2014-2015 GMC Sierra LD and HD.

GM also recalled 120,426 Buick Regals from the 2011-2013 model years and Chevrolet Malibus from 2013 for internal turn signal indicators that may not work. GM said it isn’t aware of any injuries or fatalities related to this recall.

Other cars involved in the six recalls today include the 2014-2015 Chevy Spark to fix a lower control-arm bolt and 2015 Chevrolet and GMC large sport-utility vehicles with roof carriers that may have been attached with the wrong retaining nuts.

GM fell 35 cents, or 0.9 percent, to $37.41 at the close in New York.

GM has surpassed the record for U.S. safety fixes by an automaker in a calendar year. With today’s new recalls, the tally is 25.5 million for the U.S. and 28.8 million for North America. That eclipses Ford Motor Co. (F)’s single-year record of 23.3 million in 2001.

By comparison, automakers are projected to sell 16.1 million new cars and trucks industrywide this year, according to the average of analysts’ estimates compiled by Bloomberg.
