Bad Rear Calipers

This bulletin applies to a host of GM vehicles including 2018-2019 Buick LaCrosse and Regal, Cadillac XTS, Chevy Bolt EV, Cruze, Equinox, Impala, Malibu and Volt and GMC Terrain.

GM has recalled certain of the above vehicles because the rear brake caliper pistons may have an insufficient coating, causing gas pockets to form, potentially reducing rear brake performance.
