Hi-Step'n370Z

I own a 2010 370Z Roadster with the Touring Package and Navigation, and it was built in July of 2009.

I wanted to let you know that I took my 2010 Z to the dealer yesterday and asked them to check into the lock problem.

The Tech looked under the steering column and saw that the lock in my Z has the part number: 48700-JF00D.

He told me that I already have the replacement part that replaces the number's 48700-JF00A and 48700-LF00B, and he also think's that 48700-JF00C is included as the locks that were problematic. I understand they're called; "REV A - REV B and REV C.

It looked like Nissan installed the "REV D" during the building of my Z. I have no idea as to why they did that, and wonder if Nissan was aware of the problem's in the 2009's and early built 2010's, and by July had changed to the "REV D's".

But, that wouldn't explain later year models having the locks with the bad numbers.

My point her is that - IT LOOK'S LIKE - if you have a 2010 Z, and it was built in July of 2009, then you have a good chance of already having the replacement lock installed from the factory.

If you can, crawl under the steering column and take a look at the number. It's printed on a white tag that's stuck on the lock, or take it to a Nissan Dealer and have them take a look for you.

Also, I want to thank those on this Forum for making me aware of this issue, and for supplying so many posts filled with really informative and useful information.

Thanks again to all of you.
