The National Highway Traffic Safety Administration (NHTSA) stated that airbag indicator lights may prompt malfunctions in 749,312 General Motors’ trucks.
The NHTSA probe covers SUVs and pickup trucks from Cadillac, Chevrolet, and GMC – and they have shared documents about the investigation. According to this documentation, there have been 15 complaints, and eight confidential statements made to the NHTSA. So far no major injuries or fatalities have been reported.
Here is the focus for their investigation:

The Office of Defects Investigation (ODI) has received fifteen consumer complaints on alleged airbag system malfunctions on certain General Motors (GM) vehicles. Nine of the consumer complaints allege the illumination of an airbag malfunction indicator (MIL). Six crash incidents have significant frontal collision damage where driver frontal airbags failed to deploy. all the complaints received by ODI involve either GM vehicles (Model Years 2020 and 2021 Silverado, Sierra, Tahoe, Suburban, Yukon, Yukon XL, Escalade, and Escalade ESV) covered by GM Technical Service Bulletin (TSB) 21-NA-005.”DOT/NHTSA
