SERVICE INFORMATION
The control motors for the power rear hatch (back door) are calibrated for smooth and even operation.
Adjustments or position change of the back door hinges or striker requires the back door to be re-calibrated.
The following are examples that can cause hinge position change requiring re-calibration:


Manually opening the back door aggressively, such that above normal force is exerted on the hinges as
the door stops at the full open position.



While opening the back door a wind gust pushes the door open, exerting above normal force on the
hinges as the door stops at the full open position.



With the back door open, the side of the door is heavily bumped.



Purposely performing adjustment to the door hinges or striker.
NOTE: If the back door reverses and closes while opening with an automatic/power open operation, it
is an indication that re-calibration is needed.

The Service Procedure in this bulletin provides the steps for back door re-calibration.

Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained
individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe
that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this
applies to your vehicle.
