Sept. 11, 2019—General motors is under pressure from the federal government and as a result, is recalling more than 3.4 million pickup trucks and SUVs, reported The Detroit Free Press.

GM says a pump in the power-assist brakes can put out less vacuum power than needed, increasing stopping distance and the risk of a crash.

The recall covers the Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 pickups from the 2014 through 2018 model years. Also included are the Cadillac Escalade from 2015 to 2017, and the GMC Yukon and Chevy Suburban and Tahoe from 2015 through 2018.

NHTSA began investigating the problem last year after getting 111 complaints. The agency at the time reported nine reports of crashes that caused two injuries.
