U.S. regulators are investigating reports of faulty breaks for recent models of General Motors pickups and SUVs.
The National Highway Traffic Safety Administration (NHTSA) has received more than 100 consumer complaints, which include nine crashes and two injuries, from brake issues in 2014 through 2016 Chevrolet Silverados, Suburbans, and Tahoes, as well as GMC Sierras, Yukons, and Cadillac Escalades.
In total, the brake issue could affect more than 2.7 million vehicles.
The NHTSA points to brake vacuum pumps as the likely issue. The agency said that “a brake vacuum pump can deteriorate, causing increased braking effort and longer stopping distances.”
GM spokesman Tom Wilkinson said that GM is monitoring complaints and warranty claims about the brakes and is working with NHTSA to evaluate them. Owners with brake problems should have their vehicles inspected by a GM dealer or repair shop and keep their receipts should there be an official recall.
In September, the car manufacturer recalled 210,000 of its 2018 and 2019 vehicles for brake issues, but no relation between the two incidents has been suggested.
As of now, there is no time table for a decision as the agency is determining the cause, severity, and frequency of the brake problem.
