Service bulletin 18-047-14

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Flash: Surge, Shudder Or Pulsation At Highway Speeds This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software. A small number of customers may experience a surge, shudder or pulsation type sensation when driving on smooth road surfaces at highway speeds of 37-62 mph (60-100 km/h). Some customers may also describe the sensation similar to that of a fish biting on a fishing line (fishbite) .If the customer complains of the above condition, perform the Repair Procedure.
