Service bulletins for the 2019 Infiniti QX50

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.

PARTS UPDATE - P2018-10-01. Service bulletin. FUEL SYSTEM, GASOLINE; FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:INJECTORS. Fuel Injector Replacement Retailer Inventory ***** Parts Update ***** 100% of retailer inventory parts need was automatically shipped to affected retailers the week of July 23, 2018. The purpose of this update is to inform retailers that 14035-5NA0A Intake Manifold Gaskets are on temporary parts restriction. Intake manifold gaskets may be incorrectly packaged and a PDC stock check is currently in progress to confirm. If necessary, retailers may place a replacement order via DBS as an SVC order type only. Orders will be filled as parts become available on a first in, first out basis. Retailers should ensure that the correct part numbers and quantities are ordered for each VIN. Retailers can refer to IPSB16-384 for specific ordering instructions. As mentioned above, retailers should already have enough parts to repair affected inventory need with the exception of any incorrectly packaged 14035-5NA0A Intake Manifold Gaskets. Any parts necessary for this repair that are not restricted will need to be placed separately via normal ordering process.
