Steering Lock Failures on the Nissan 370Z and GT-R
As you will have read on nissansportz.com and many other forums, there is a known potential fault with the steering locks fitted to early 370Z and GT-R cars. This guide has been compiled from information from our members, our own investigations and through communications with Nissan UK.
The aim of this is to provide facts on the failures and cut out any hearsay and myths with regards to this issue so you know where you stand.
As part of the keyless entry system, the 370Z and GT-R are fitted with a solenoid that activates / deactivates a steering lock in conjunction with the car’s ignition. This effectively does the same job as the physical lock on a car with a conventional key.
When the ignition is turned on (and the car goes into ACC mode) the solenoid releases the lock. As a safety feature, a status signal is passed back to the BCU to confirm the solenoid has operated successfully.
It has been seen that some early 370Z and GT-R cars a fault occurs whereby the signal indicates a failure, or potential failure, in the lock - resulting in a ‘yellow key’ error light on the dashboard. Note, this is not to be confused with the initial ‘illumination check’ procedure the dash goes through to prove all the warning lights are working. The red arrow in the pictures below show the location of the warning light.
370Z Key Light:
GT-R Key Light:
If the key warning light is activated when the ignition is turned on then the car will become disabled and will not start as a safety precaution. If the light comes on whilst driving then the car will continue to run and may restart OK but it is an indication that the steering lock will fail.
This is the section from the 370Z Manual:
What has Nissan done to prevent this happening?
An upgraded part for the GT-R/370Z steering lock went into factory production in March 2010. For the 370Z, any car with VIN’s SJN12AAZ34U0200746 or SJN1GAAZ34U0300622 and higher will have the upgraded part.
The revised steering lock has part number #48700-JF00C and since then, later revisions (#48700-JF00D, #48700-JF00E, etc.) have also been produced.
What happens if my car has the older part number?
If your car has the older part fitted then there is the potential for this part to fail. This does not mean that it will fail.
Be vigilant and if you experience the fault contact Nissan Customer Services (details below).
What happens if my steering lock fails?
Firstly, you should have pan-European RAC cover – this is renewed for free every time you service your car with a Nissan dealer. You should not have to pay to have your car taken to the dealer if the lock has failed and you are unable to drive the car.
Call Nissan Customer services (details below) as soon as you are able to report the fault and get a Case Reference Number.
If your vehicle is in a warranty, the repair should be covered by the Pan European warranty. For those vehicles out of warranty the cost of the part has been reduced by Nissan to £465. Nissan will also consider any steering lock failure for a gesture of goodwill, potentially reducing the cost of the repair.
How long will it take to fix?
At the time of writing there is currently a 3-week lead time on this part. Nissan acknowledge this is not acceptable and are in the process of organising a fast-track solution. In the mean time, Nissan will endeavour to provide you a loan car.
