    Brake system issue

    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.

    Consequence

    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. GM's number for this recall is 18279.

What the ratings mean

NHTSA gives the 2018 Chevrolet Impala 5 out of 5 stars overall, level with the 5-star median for the 7 comparable 2018 vehicles NHTSA rated in this class.

NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.

NHTSA's dynamic test put this vehicle's rollover probability at 12.1% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.

How this compares

At 25 MPG combined, the 2018 Chevrolet Impala ranks 5th of 10 large cars EPA rated for 2018 — exactly the 25 MPG median for that group.

That places it a little below the middle of its class. If annual mileage is high, the running-cost gap against a class-average rival compounds quickly.

EPA puts annual fuel spend at about $2,450, $200 less than the $2,650 typical for the class. Over five years at 15,000 miles a year that is roughly $12,250, a $1,000 difference against a class-median vehicle.

Tailpipe CO₂ is 360 grams per mile — about 5.4 metric tons over 15,000 miles of driving.
