Official 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.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
