Around 2.2 million Honda vehicles undergo an engineering analysis by the National Highway Traffic Safety Administration (NHTSA) because of engine restart failure concerns. The investigation targets incidents where Honda vehicles do not restart their engines automatically when Auto Idle Stop begins at traffic control points.

The NHTSA's Office of Defects Investigation processed 1,384 customer complaints about engine restart failure incidents. Such a malfunction creates dangerous risks because it leaves drivers stuck in damaging traffic conditions.

All reported conditions disclosed to authorities showed four accidents coupled with fires while two other instances resulted in injuries. An engineering analysis by the NHTSA has become necessary since the reported incidents showed severity which determines the extent of this issue.

The research examines the Auto Idle Stop feature because this system lowers fuel usage by shutting off the engine when a vehicle stands completely still. This system has encountered restart failures which led to safety issues with its operation.

An engineering analysis by NHTSA will study the Honda vehicles under evaluation while evaluating Auto Idle Stop system design and operational behavior. The agency intends to both find the fundamental reason for restarted engine malfunctions along with analyzing future incident likelihood.

The probe surveys many Honda vehicles and a failure to determine safety defects can trigger mandatory recalls. The investigation requires Honda to give all essential data and information to authorities and also participate in the investigation process.
