Recalls and investigations

One recall on the transmission and drivetrain covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.

20V-668Oct 29, 2020
Power Train:Automatic Transmission

General Motors LLC (GM) is recalling certain 2018-2019 Chevrolet Cruze and Buick LaCrosse, 2018-2020 Chevrolet Equinox, Chevrolet Traverse and GMC Terrain, 2018 Chevrolet Malibu, 2019-2020 Buick Encore, Buick Enclave, Cadillac XT4, Chevrolet Blazer and GMC Acadia, and 2020 Cadillac XT6 vehicles.

“The vehicle was struggling to pick up the gears and stalled in the road. After having it checked at the Chevy dealer stated it was the Transmission that needed to be replaced. The vehicle is unable to reverse due the the transmission issue. Unable to drive. There is no active recall for this issue which is concerning, considering I've read multiple drivers have the same issue with the 2018 Chevy traverse.”

Should you keep driving it?

This page can't tell you that. 1 of 70 reports involved a crash and 5 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
