NHTSA Investigation PE15015

Inconsistent Throttle Response

This investigation was opened on April 20, 2015 to investigate reports of inconsistent throttle control on all MY 2015 HD XG750 and XG500 motorcycles.At the time, ODI had 14 consumer complaints and no crashes reported.At the time of closing this investigation ODI has 51 reports (6 of which allege a crash occurred). In addition to requesting information from Harley-Davidson (HD), ODI interviewed complainants and dealer service/parts department personnel.ODI staff also test rode one of the crash bikes to experience the alleged condition first-hand.At low fuel levels (typically below .8 gallon), the engine may stumble and/or stall when fuel flow from the pump to engine is interrupted.This is due to a poor seal at the fuel pump inlet. Ultimately, HD decided to recall (15V-474) the affected motorcycles (MY 2015 XG500 and XG750 produced 1-20-14 through 6-24-15) to install a new fuel pump assembly.With the recall, our information request is moot and this PE is closed.

An investigation is a separate record from a recall and from a manufacturer communication. A manufacturer campaign to repair a safety defect or a failure to meet a federal safety standard.
