Q50 Direct Adaptive Steering Owner Letter - FINAL
OWNER NOTIFICATION
Dear Infiniti Q50 Owner:
Infiniti is committed to providing the highest levels of product safety, quality and customer
satisfaction. With that in mind, we want to bring to your attention important information
regarding a voluntary service campaign to update the Direct Adaptive Steering™ (DAS) system
on your vehicle.
REASON FOR SERVICE CAMPAIGN
In certain conditions such as freezing outside temperatures or a drop in battery charge at
startup, the current DAS system software calibration may switch the system to a manual
steering mode that requires a noticeable increase in steering effort and illuminates one or more
error messages on the vehicle information display. To help prevent this from occurring, Infiniti
will update the DAS software and recalibrate the system.
WHAT INFINITI WILL DO
To ensure your continued satisfaction and confidence in your Q50, your authorized Infiniti
retailer will perform a DAS system diagnostic check, software update, and recalibration. In
certain instances, your Infiniti retailer may need to replace the DAS control units. All services
will be performed at no cost to you for parts or labor. This service should take approximately 2
hours to complete, but your Infiniti retailer may require your vehicle for a longer period of time
based upon their work schedule.
WHAT YOU SHOULD DO
Please contact your Infiniti retailer at your earliest convenience in order to set an appointment
to have your vehicle upgraded at no expense to you. Please bring this notice with you to your
service appointment. We understand your time is valuable so your retailer will work with you to
make the update as convenient as possible.
Thank you for your cooperation and we are indeed sorry for any inconvenience this may cause
you.
Should you have any questions, our representatives would be pleased to assist you.
