The National Highway Traffic Safety Administration has issued a safety recall for a large number of GM vehicles that may have a faulty airbag malfunction warning light.
The problem: affected vehicles may have a communications gateway module that incorrectly processes a loss of communication with the sensing diagnostic module (SDM), causing the air bag malfunction indicator light to inconsistently illuminate.
The hazards: the airbag malfunction warning light comes on when there is no actual problem with the airbag, the user could be led to believe the vehicle airbag has malfunctioned when in reality, it hasn’t. Conversely, if the user observes the warning light flickering on and off intermittently, seemingly without reason, they may no longer see it as a valid identifier of an airbag malfunction.
The fix: GM dealers will be instructed to update the software in the communications gateway module. These repairs will be performed at no cost to the vehicle owner.
Affected components: communications gateway module, airbag malfunction warning light.
Number of affected vehicles: a total of 285,622 GM vehicles are affected by this airbag malfunction warning light-related issue.
