US probes flaw in GM trucks, SUVs
U.S. highway safety investigators are probing an alleged defect in 2.7 million pickups and sport utility vehicles built by General Motors Co. that are getting into collisions because drivers are having trouble braking.
The National Highway Traffic Safety Administration opened an investigation on Tuesday of trucks and SUVs including GM's best-selling Chevrolet Silverado after receiving 111 complaints from consumers. The power brake vacuum pump in the models can degrade and make it difficult to stop, according to the agency. There have been nine crashes related to the problem and two injuries, NHTSA said.
The investigation involves the 2014 to 2016 model year Chevy Silverado, Suburban and Tahoe; GMC Sierra and Yukon; and the Cadillac Escalade. GM has been monitoring field reports and other data on the vehicles and will cooperate with NHTSA to evaluate them further, said Tom Wilkinson, a company spokesman.
GM shares have traded down 12 percent this year, trailing the S&P 500 Index's 1.2 percent decline.
