General Motors announced a recall Wednesday of 3.46 million GM trucks and SUVs for a braking issue that has been linked to 113 accidents and 13 injuries. The problem arises from a vacuum pump issue where the pump make less vacuum over time, thereby increasing the braking effort. The pump is lubricated by engine oil and can accumulate debris and oil sludge lessening the pump's effectiveness.
The recall covered model years 2014 - 2018 of Cadillac Escalade, Chevrolet Silverado, Suburban, and Tahoe, and GMC Sierra and Yukon.
GM told the NHTSA that the pump design was only used during those years of manufacture.
In a smaller recall, GM is recalling 177,000 2018 Chevrolet Malibus with the 1.5-liter Turbo engine where an error in the engine control computer could disable the fuel injectors.
