GM is issuing a recall for some 194,100 model-year 2018-20 Buick, Cadillac, Chevrolet and GMC vehicles due to missing or loose bolts on the stop-start accumulator endcap, which involves a part of the drivetrain that helps the system switch from the brake to the accelerator.

Missing or loose bolts on the endcap could result in a transmission oil leak and may progress to a loss of propulsion, increasing the risk of a crash. Additionally, a transmission fluid leak in the presence of an ignition source may increase the risk of fire. Affected vehicles include model-year 2018-19 Chevrolet Cruze and Buick LaCrosse cars; model-year 2018-20 Chevrolet Equinox and Traverse and GMC Terrain SUVs; model-year 2018 Chevrolet Malibu cars; model-year 2019-20 Buick Encore and Enclave, Cadillac XT4, Chevrolet Blazer and GMC Acadia SUVs; and model-year 2020 Cadillac XT6 SUVs.

To resolve the issue, dealers will inspect the stop-start transmission accumulator, and replace the unit for free if any bolts are missing. Buick, Cadillac and Chevrolet manufacturer GM will begin notifying owners Dec. 14. Owners can call Buick at 800-521-7300, Cadillac at 800-333-4223, Chevrolet at 800-630-2438, the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236 or visit its website to check their vehicle identification number and learn more.
