Why it matters: If the child seat cannot be attached correctly to the anchorage bar, there is an increased the risk of injury.
The fix: Gm will notify owners, and dealers will inspect, remove any excess adhesive, and apply anti-corrosion primer to the inboard child seat anchorage bars, free of charge. The recall began August 3, 2018.
