Shares of General Motors (GM - Get Report) were falling in trading Wednesday after the automaker announced it was issuing a recall for 3.5 million vehicles across four different brands because of a braking issue.
The recall involves the Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 pickups from the 2014 through 2018 model years, the Cadillac Escalade from 2015 through 2017 and the GMC Yukon and Chevy Suburban and Tahoe from 2015 through 2018.
The company said that a pump in the power-assist brakes can put out less vacuum power than needed, which increases the stopping distance and increases the risk of a crash.
The National Highway Transit Safety Administration began investigating the issue last year after getting 11 complaints from owners who said their brakes were underperforming. The government agency recorded nine reports of crashes that caused two injuries.
GM shares were down 0.37% to $39.44.
