I took my 2009 to the Dealer this past week and they told me my car had a Recall. I asked if it was the Steering lock.
I told them that it was replaced about 3 to 4 yrs .ago.
The Service Coordinator told me that Nissan told them they have to replaced mine again because of a new REV. They had to order the part which already came in.
So I'm not sure what is still going on with this issue..... but all 370Z Steering lock issue should be covered by Nissan
