tell the dealer to check the steering lock revision. there's a barcode on the unit they can scan to get datecode and revision number. If your car has RevA or RevB, it needs to be changed.

also remember that this problem seems to occure more when the battery is weaker (colder weather, some cars with 3yr old poorly maintained batteries). if your battery has better cca due to warmer day, etc. chances are it can make the failed unit work again temporarily.

The ECU is just what they said over the phone. They have not even seen the car yet. It was just a wild guess/possibility.

I didn’t realize there was a proper way to maintain the battery. How does one maintenance a car battery. I get my oil changes at the dealership every time.

the battery need to be charged and floated when not in use. especially if your car is a hobby car like mine it needs to be on a battery manager (battery tender) during the week or during hibernation.

my dd (G35C) is also on battery manager on the weekends. my short 22mile round trip commute (where half is bumper to bumper) is not enough to charge the battery. my car is 7.5yrs old and still running factory battery. :p

I use my car every day of the year. Normal size trips.

yah, most car batteries seems to only last about 3-4yrs these days under normal use. in favorable climate it might last longer but not by much.

weak battery apparently contributes to the failure but not the root cause. :)

This just happened to me today. On the way to work this morning and I stop to get some gas. No issues. Get back into the car and press start and uh oh, nothing. I tried both keys and a jump, but still nothing. I got a flatbed tow to the dealership and luckily for me, it was RIGHT across the street. Unlucky for me, it turns out it was my steering lock unit malfunctioning and costs $800 bucks for them to order and it won't come in for a week. They have no loner cars available either. I love it.

kenchan 12-17-2011 10:47 AM

sorry to hear xsaintx. so you locked your car when you stopped in for gas? or left the door unlocked?

im starting to think keeping the doors unlocked doesn't help cause the steering locks anyway when the car is turned off...

Add one more Z falure
 
My 2010 with 7200 miles died in a Wal-Mart lot Friday afternoon. The key emblem lit up and brake pedal stiff and locked in park. Had it hauled to dealer Sat morning. Hope for Mon or Tues fix. At least it is still under warranty.

Megan370z 12-19-2011 11:34 AM

ohhh well, on my first day of Christmas vacation , I have that same problem that you guys have been dealing with !!

the Z is waiting for the towing and then process his way to the dealership !
I'm about 3000kms from my warranty to expire ! thats a good timing after all and my steering lock assy is #48700-JF00B

At the rate these are failing on this forum alone, I hope Nissan would "goodwill" those with problems out of warranty in the future...

i hope they just do a recall for all affected Z's regardless of warranty and be done with this non-sense.

it's bad enough nissan used the same bad parts on affected non-GTR cars and did not 'drill deep and wide' on this quality issue. i am 99.99% sure nissan's intelligence is aware of this issue.

Had this problem a couple weeks ago and had the steering lock replaced under warranty..
I knew what the problem was as soon as the car wouldn't start and showed the key fob symbol on the dash..

cevans87 12-20-2011 03:09 PM

Well they did a "goodwill" of a whopping $200 towards any service needed on my Nissan. Such ********.

I told the woman on the phone that plenty of us on the forums have had this happen and this is my 3rd Nissan, it is unacceptable that this happened and isn't being covered. My car is only 4000 miles out of warranty and I paid $1200 out of pocket to have it fixed.

She went on to say that it was a non-negotiable offer. I said it was ridiculous that they are aware of problem and refuse to actually do an official recall. I stated that I'd like to talk to the person who she talked to about getting me the "good will" payment, she said "He doesn't talk to customers"

I was pretty livid, I was able to get his title and an address in Tennessee where their Corporate offices are located. I will probably wind up writing them a letter, but I'm doubting anything useful will come of it. I'll post it later when I get home as it's scribbled down on a sheet of paper. I'll also give everyone here her direct extension, maybe you can at least get 2 free oil changes (whoop-de-doo)
