General Motors has issued a Voluntary Emissions Recall for select units of the 2019 Chevy Silverado 1500 pickup truck due to a problem related to a faulty Engine Control Module (ECM).
The problem: affected vehicles equipped with the turbocharged 2.7L I4 L3B gasoline engine may have a condition where the ECM fails to properly diagnose, set Diagnostic Trouble Codes (DTCs), or illuminate the Malfunction Indicator Light (Check Engine Light) if certain fault conditions of a catalytic converter failure were to occur.
The hazards: if the ECM were to improperly diagnose an emissions-related issue, the affected vehicle has the potential to fail emissions testing.
The fix: certified GM technicians will be instructed to inspect the ECM and reprogram as necessary. It should take techs roughly 45 minutes to perform the fix. It’s worth noting that some owners may be eligible for reimbursement.
Affected components: Engine Control Module (ECM).
