Cars need to go, and they need to stop, which is why General Motors will recall almost 3.5 million trucks and SUVs because of a possible issue with a vacuum pump that could make braking more hard, according to Reuters. Affected models include the Chevrolet Silverado and GMC Sierra and their 1500, 2500 and 3500 variants from the 2014-2018 model years, and the Chevy Tahoe, Suburban, GMC Yukon and Cadillac Escalade from the 2015-2018 model years.

According to GM, as the pump in power-assisted brakes age, they may put out less power than needed, increasing stopping distance and the risk of a crash.

The recall comes following a lengthy investigation by the National Highway Traffic Safety Administration, which began previous year in November.

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

Dealerships will recalibrate the vehicle's electronic brake control module to remedy the problem. Owners were to be notified starting September 6.

According to the automaker, the problem lies within the vacuum pump. The vacuum assist pump is lubricated with engine oil that flows into the pump through a filter screen, but GM said the design may cause the system to lose effectiveness over time due to debris such as oil sludge accumulating on the filter screen.

Drivers could feel a vibration in the brake pedal or a change in pressure required to push the brake pedal if their trucks have the vacuum pump problem. 5-litre turbocharged engines. GM says in documents posted Wednesday on the NHTSA website that a software error can corrupt data used by the engine control computer.
