The recall covers Chevrolet Silverado and GMC Sierra 1500 light-duty pickups from the 2014 through 2018 model years. It's not clear if there are more crashes or injuries related to the recall. There have been more than 100 complaints from truck owners of poor brake performance, and there have been reports of almost a dozen crashes that caused two injuries. Then in July, the federal agency provided the Detroit-based automaker with additional information, which prompted the company to open its own investigation into the issue.
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.More news: Kevin Hart's Wife Eniko Offers Update On His Health After Hospital Release

GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen.
GM discovered the problem and reported it to the National Highway Traffic Safety Administration, according to the report.
GM also is recalling over 177,000 Chevrolet Malibu sedans from the 2018 model year in the USA because the fuel injectors can fail.
General Motors has plans for a massive new recall campaign that involves some of its most popular vehicles.
