Airbags Vehicle recall #20V446000 · 2020 · 769 vehicles
What's wrong: General motors, LLC. (gm) is recalling certain 2020 Buick enclave, Cadillac xt5 and xt6, Chevrolet blazer, silverado 1500, 2500 and 3500 and traverse and GMC acadia and sierra 1500, 2500 and 3500 vehicles. The diffuser component of the roof-rail air bag (rrab) inflator May not have been properly crimped to the inflator and could separate from the inflator during air bag deployment.

The fix: Gm will notify owners, and dealers will replace the suspect rrab modules, free of charge. The recall began September 3, 2020.
Fuel system Vehicle recall #20V639000 · 2020 · 2,781 vehicles
What's wrong: The fuel pump's jet nozzle May have a plastic burr remaining from the manufacturing process, possibly causing a blocked nozzle and an insufficient fuel supply to the engine.
Why it matters: Insufficient fuel supply can result in an engine stall without warning, increasing the risk of a crash.
The fix: Gm will notify owners, and dealers will replace the fuel pump module. The recall began November 16, 2020.

The fix: Gm will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021.
