General Motors Co. is calling back 3.5 million large pickup trucks and SUVs in the U.S. to fix power brake boosters that may fail.
The campaign supplements a similar recall that began in June to fix the same flaw in 310,000 vehicles in Canada. Affected vehicles are fitted with power brake boosters that may gradually lose vacuum and stop providing the expected level of brake assist.
The two recalls target certain 2014-2018 model Cadillac Escalade SUVs; Chevrolet Silverado pickups (pictured) and Tahoe and Suburban SUVs; and GMC Sierra pickups and Yukon SUVs.
The National Highway Traffic Safety Administration says the defect has prompted 111 operator complaints and at least nine crashes in the U.S. The agency has been investigating the underlying cause of the malfunction since last November.
GM dealers aim to remedy the problem with a software update that modifies the behavior of the vehicles’ brake control module.
It’s the fifth generation of a vehicle that has been increasing in sales year after year since its introduction in 1997.
