## NHTSA's summary

A customer may experience a hesitation or shudder while driving approximately 30\-55 mph and at 1400\-2000 RPM. The engine speed begins to visibly flutter on the tachometer. This occurs during warm up after a cold start. This hesitation is felt under these conditions while maintaining a constant accelerator pedal position.
