(CNN) General Motors has issued a recall of 3.4 million pickup trucks and SUVs in the US in order to fix a problem with brakes in the vehicles.

The issue has resulted in 113 accidents and 13 injuries, although no fatalities have been reported, GM spokesperson Dan Flores tells CNN.

"General Motors is voluntarily recalling certain 2014-2018 model year Cadillac Escalade, Chevrolet Silverado, Chevrolet Suburban, Chevrolet Tahoe, GMC Sierra, and GMC Yukon vehicles for a condition related to increased brake pedal effort," GM said in a statement. "In rare circumstances, these vehicles may have a condition in which the engine-mounted mechanical vacuum pump output may decrease over time, decreasing the amount of vacuum/power brake assist."

As the pumps in the power-assist brakes put out less vacuum power than is needed, "customers may experience increased brake pedal effort, hard brake pedal, and/or potentially increased stopping distance."

All of these issues could increase the risk of a crash.
