General Motors will be contacting the owners of certain 2021 Chevrolet Traverse and 2021 Buick Enclave SUVs, about a problem that could result in the front air bag not deploying properly. Owner notification letters are expected to be mailed out beginning of August 2021.

According to the defect report, during a weekly service programming system (SPS) audit, it was discovered that a small number of 2021 Chevy and Buick models may have been manufactured with the incorrect sensing diagnostic module (SDM) data calibration. The data files were corrected in the SPS system and the problem was reported to GM’s safety program. Their investigation found a small number of 2021 Chevrolet Traverse and 2021 Buick Enclave vehicles may have received the same incorrect data and decided to conduct a safety recall.

General Motors will be contacting the owners of affected vehicles with instructions to update the calibration software in the SDM. GM’s number for this recall is N212340220 and the NHTSA campaign number is 21V-472
