General Motors said Tuesday that it will recall 230,000 vehicles to fix a problem with their brake systems that could affect their stopping distances. The recall covers certain examples of 2018 and 2019 model year Buick LaCrosse sedans, Cadillac XTS sedans, Chevrolet Cruze, Impala, and Malibu sedans, Chevrolet Bolt EV electric cars, and GMC Terrain and Chevrolet Equinox crossover SUVs. GM said that about 210,000 of the recalled vehicles were sold new in the U.S., while the others were delivered to Canada. At fault are rear brake pistons that GM said in government filings were improperly chromed and tempered when they were manufactured.
