***** Campaign Summary *****
Infiniti is conducting a Voluntary Service Campaign on certain MY 2014-15 Q50 vehicles
equipped with Direct Adaptive SteeringTM (DAS) system to update the DAS software to the
latest production standards. In extreme cold conditions (approximately -13 degrees F/-25
degrees C), the current system software calibration may default the system into manual
steering mode that has some increase in steering effort upon starting the vehicle and
illuminates one or more error messages on the information display. While the manual mode
results in some increase in steering effort, the steering continues to function preserving
vehicle control. To help prevent this Direct Adaptive Steering issue from occurring, Infiniti
will update the system’s software.
Q50 Hybrid vehicles located in cold climates and subject to the P5323 or P5326 campaign
will have the 12-volt battery replaced as part of the campaign as well. The 12-volt battery is
being upgraded to a heavy duty battery on these vehicles to support system operation in
cold climates.
Infiniti performed a DAS software update in early 2014 to help improve extreme cold
weather performance. However, in the interest of continuously high level of client service
and satisfaction, Infiniti is making additional DAS software updates available to all clients.
***** What Retailers Should Do *****
To ensure client satisfaction, retailers are asked to perform the following repair procedure
prior to sale. Once repaired, vehicles can be sold without further action.

***** Retailer’s Responsibility *****
It is the retailer’s responsibility to check SERVICE COMM using the appropriate Campaign
I.D. for the campaign status on each vehicle falling within the range of this voluntary
service campaign which for any reason enters the service department. This includes
vehicles purchased from private parties or presented by transient (tourist) owners and
vehicles in retailer inventory. If a VIN subject to this voluntary service campaign was part
of a retailer trade, the letter associated with that VIN should be forwarded to the
appropriate retailer for repair completion.
Frequently Asked Questions (FAQ):
Q.

Is this a safety recall?

A.

No, there is no safety defect. This is a service campaign being conducted to update
the DAS to latest production standards, but it is important that your vehicle is
remedied if your received a notification letter. While the manual mode results in
some increase in steering effort, the steering continues to function preserving vehicle
control.

Q.

Is a STOP SALE in effect?

A.

No, but retailers are requested to perform this campaign on affected vehicles in their
inventories prior to sale to ensure client satisfaction.

Q.

What is the reason for this voluntary service campaign?

A.

In extreme cold conditions (approximately -13 degrees F/-25 degrees C), the
current system software calibration may default the system into manual steering
mode that has some increase in steering effort upon starting the vehicle and
illuminates one or more error messages on the information display. While in manual
mode the steering continues to function preserving vehicle control. To help prevent
this Direct Adaptive Steering issue from occurring, Infiniti will update the system’s
software.
Q50 Hybrid vehicles located in cold climates and subject to the P5323 or P5326
campaign will have the 12-volt battery replaced as part of the campaign as well. The
12-volt battery is being upgraded to a heavy duty battery on these vehicles to
support system operation in cold climates.

Q.

What will be the service department action?

A.

To ensure client satisfaction and confidence, Infiniti will reprogram the DAS control
units with updated software that increases DAS relay coil voltage, which heats the
relay at a rate that prevents ice from forming and accumulating. Retailers will also
replace the 12-volt battery on vehicles subject to this campaign.

Q.

How long will the software update take?

A.

This enhancement should take approximately 1.5 hours to complete, but your
retailer may require your vehicle for a longer period of time based upon their work
schedule.

Q.

When will vehicle owners be notified?

A.

Owners of all potentially affected vehicles will begin to be notified the week of
December 14, 2015 via U.S. Mail to take their vehicles to an Infiniti retailer for repair
at no charge.

Q.

Are parts readily available?

A.

Yes.

Q.

Is it safe to use my vehicle until the repairs can be made?

Alternate transportation may be provided under Infiniti’s Courtesy Vehicle Program
while your vehicle is being serviced. This is subject to vehicle availability. Check
with your retailer for availability and further details.

Q.

I have lost confidence in the vehicle. Will Infiniti replace or repurchase the
vehicle?

A.

We apologize for any inconvenience this may have caused. The repair will correct
this condition. As the condition will be corrected, there is no basis on which to
repurchase or offer you a replacement vehicle.

Q.

Will I have to take my vehicle back to the selling retailer to have this service
performed?
