2009 NISSAN 370Z with 37000.0 miles

Lock set - steering models jf00a,jf00b and jf00c are faulty. Recall was done on Nissan gt-r for the faulty part. The same part is in the 2009-11 370z and suffers the same defects but was not included in the recall. Car will not start with a faulty lock set - steering. Part is known to be defective as indicated by the recall from Nissan (campaign id# P0309) for the identical part in the 2009 gt-r. Nissan must recall this faulty part in the 370z and reimburse customers who have paid for costly repairs and/or replacement parts due to a part know to Nissan (as evidenced by the gt-r recall) to be faulty.

2009 NISSAN ALTIMA HYBRID with 57000.0 miles

The steering lock unit (part number 48700-9n00b) needed replacement. The steering lock unit did not properly engage when the vehicle was turned off. Because the unit did not engage, the vehicle would not start. I was left stranded in a parking garage at night and had to have the vehicle towed. The nearest dealership was in alexandria, va. They charged $900 to diagnose and repair this problem. Since the vehicle had over 36,000 miles, it was not covered under warranty. This is a widely known issue with Nissan vehicles and is present on several online forums. Most of the steering lock unit failures occur after the warranty period, but before 60k miles. There is an existing safety recall for the 2009 Nissan gt-r model for the steering lock unit (campaign id P0309). This is Nissan's top tier vehicle. At this time Nissan has chosen not to issue a recall for other models to include the altima. Anyone driving a Nissan with this known issue can be stranded at any time.

2009 NISSAN ALTIMA with 58000.0 miles

On a recent cold morning i got into my 2009 Nissan Altima, at 7:00 am and drove son to school. Came home and parked vehicle. Got back in car at 3:00 pm and car would not start. The car had been fine that morning. Push start would not get out of "lock" position. Headlights, inside lights, brake lights all worked. Steering wheel was not locked. Would not get out of "park". Battery was tested and not the problem. Fuses were checked and brake switch checked and not the problem. Looked on internet and found multiple incidents where steering lock mechanism was faulty on 2009 Nissan Altima, and was not engaging and therefore the car would not start and was locked by immobilizer. The only option is a $500.00 plus part from Nissan and another $500-600.00 to install. Car was towed to dealership at cost of $109.00 to me, and the estimate from the dealer to fix the now diagnosed steering lock malfunction was $1,100.00 making this a total cost of $1,209.00 on a vehicle that has less than $60,000 miles. I looked on the internet and found the following information by another dissatisfied customer : 1. Nissan did a recall on their more expensive model Nissan gtrs was recalled, part number 48700-jf00a or 48700-jf00b, being replaced by 48700-jf00c and called campaign id P0309. 2. Same part number is failing for Nissan 370zs as well, same years and same part number 48700-jf00a or 48700-jf00b, yet they are not being recalled. 3. This problem is also occurring in Nissan maximas and Nissan muranos however i could not find the part number. 4. In all models of Nissan this part was removed in mid 2010 due to consistent failure. There should be a make-wide recall for all models for this part, not just the gtr because it's the most expensive of them. Call 1-800-Nissan 1 and complain, i am...

2009 NISSAN 370Z with 44000.0 miles

Steering lock unit failed. "key" light indicator appeared. Car unable to start. Tow needed to dealer for out of warranty repairs. There was a voluntary recall on the same part for 2009 gtrs models (reference: ntb10-025, campaign id#: P0309. It is ridiculous that there is no recall for 370z models which uses the same defective part!!!!!!

2009 NISSAN 370Z with 50000.0 miles

Attempted to start my 370z this morning, key light would come on, and the lock light came on the push button start. But no response. After some research, it appears that the steering wheel lock mechanism is stuck halfway so the steering wheel turns but nothing is indicating to the ecu that it is unlocked. Nissan had issued a recall for the same part on 2009 gt-r's (ntb10-025 P0309) but not on 370z's. It became such an issue that in 2011/2012 Nissan stopped installing the device on the 370z model. More and more 370z owners are becoming stranded because of this defect and it should be recalled and replaced.
