Brakes (hydraulic) Vehicle recall #18V576000 · 2018 · 210,628 vehicles
What's wrong: The rear brake caliper pistons May have an insufficient coating causing gas pockets to form, potentially reducing rear brake performance.

The fix: Gm will notify owners, and dealers will bleed the vehicle's brake system, free of charge. The recall began October 11, 2018.
Seat belts Vehicle recall #18V673000 · 2018 · 15,800 vehicles
What's wrong: Certain second-row or third-row rear seatbelts retractor assemblies May not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (fmvss) number 208, "occupant crash protection."
Why it matters: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.
The fix: Gm will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018.
