After an investigation by the National Highway Traffic Safety Administration (NHTSA), General Motors is recalling 3.4 million of their trucks and SUVs, due to a problem with the vehicles’ brakes as they age.
The recall was issued on September 6.
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.
General Motors said a pump in the power-assist brakes can put out less vacuum power than needed, increasing stopping distance and the risk of a crash.
A GM spokesman Dan Flores, told Consumer Reports in an email that the company is aware of 113 crashes and 13 injuries because of the problem; no deaths have been reported.
The recall addresses a flaw with the powered brake-assist system, which reduces the amount of effort a driver needs to exert to stop the vehicle. If the system fails, a driver may find that the brake pedal takes much more effort to push. Drivers may also find that it takes more distance for their vehicle to stop, which could lead to a crash, NHTSA says.
Multiple reports on the recall state that owners were to be notified starting September 6. It was not immediately clear on Wednesday how many injuries or crashes are linked to the issue. However, GM said it could impact braking in “rare circumstances,” according to Reuters.
