Recalls and investigations

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

18V-576Aug 30, 2018
Service Brakes, Hydraulic:Foundation Components:Disc:Caliper

General Motors LLC (GM) is recalling certain 2018-2019 Chevrolet Equinox, Impala, Cruze, Volt and Bolt EV vehicles, GMC Terrain vehicles, Buick Lacrosse and Regal vehicles, Cadillac XTS and XTS Professional vehicles and 2018 Chevrolet Malibu vehicles. The rear brake caliper pistons may have an insufficient coating causing gas pockets to form, potentially reducing rear brake performance.

Risk and remedy
Risk: A reduction of braking performance can increase the risk of a crash.
Remedy: GM will notify owners, and dealers will bleed the vehicle's brake system, free of charge. The recall began October 11, 2018. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782.

“Service Stabilitrak warning will pop up on my dash. The car loses power. Push on the gas and it sputters. Had it serviced by GMC 2 years ago and now it is happening again. More frequent in colder weather. There are thousands of reddit posts about this same issue from other 2018 Chevy Malibu owners. GMC refuses to acknowledge it is a quality or performance issue on their end.”

“Cam-driven Brake Booster Vacuum failure without warning. My engine died, my brake pedal and steering wheel stiffened, while in moderate traffic. I had use excessive brake force to slow my vehicle to a stop. Currently have 78,012 miles as it is sitting in the repairs shop. This is the first time it has happened, but I worry it may happen again because upon further research, it is a very common part failure.”

Should you keep driving it?

This page can't tell you that. 6 of 68 reports involved a crash and 3 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.
