    Safety restraint issue

    SEAT BELTS:REAR/OTHER

    General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. 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."

    Consequence

    If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.

    Remedy

    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. Owners may contact 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 18315.

How this compares

At 25 MPG combined, the 2018 Cadillac CT6 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 $3,050, $400 more than the $2,650 typical for the class. Over five years at 15,000 miles a year that is roughly $15,250, a $2,000 difference against a class-median vehicle.

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