Upon attempting to start the car, ignition would not change from "lock" to "acc" or "on". intelligent key warning lamp was lit steady on dash. Steering wheel column was not locked. All power and other functions worked (lights, door locks, etc). Battery is fine. Independent testing found steering lock control module part 48700-9N00B faulty. Similar/same part on Nissan gtrs was recalled, part number 48700-jf00A or 48700-jf00B, being replaced by 48700-jf00C 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. This problem is also occurring in Nissan maximas and Nissan muranos however I could not find the part number. In all models of Nissan this part was removed in mid 2010 due to consistent failure. The part costs approximately $500 from Nissan, is usually out of stock and back ordered, and also costs another $400-$500 to be installed at a dealer. 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.

After work my wife's car would not start. The intelligent key warning light was on but the push button was non responsive even with the fob in the key fob slot. We had the vehicle towed to the dealer and was told it the steering lock control unit had gone bad and is preventing the ignition swith from working. This part should be recalled by Nissan since it prevents starting the car leaving you stranded.

Without any warning my 2009 Nissan Altima would not start. I could not depress the brake in order to start the car. The car recognized the intelligent key was inside the car, I could lock/unlock the doors and trunk, dome lights worked. Basically I was stranded. I contacted the dealer I purchased car from (whom are not familiar with Nissan vehicles) and an extended warranty, they had me troubleshoot. I called lock & key company, not familiar working with this Nissan problem. Called Nissan dealer while waiting, they advised me a typical problem with this yr/make and I was at the mercy of Nissan to repair, he forgot to tell me that it wasn't covered under any warranty program and no recall. Vehicle towed to dealership/service dept I purchased car from, they towed to local Nissan dealer. Now they want $750 for repairs on something that even Nissan is aware of (I called Nissan no. America) and they will investigate if perhaps something else triggered the sensor to not work properly. My car will stay at dealer until I get an answer and the $750. It could have happened at any time, no warning lights, car didn't act up in any way. This poses huge risks, people could be stranded at night or on the side of a road.

That didnt work eitther. So we replaced the battery. That didnt work. Still wouldnt start. Dealer came and towed it to the dealership today. Said its the steering lock assembly going bad. I need it replaced. Its not covered under warrenty. $723 it will cost me. Dealership stated they have had this issue with many many 2009 Altima.. why is this not a recalled part?

2009 Nissan Altima coupe was in parking lot and would not start. The intelligent key warning light was on dash. Had car towed to dealer. They advised steering lock control unit (part #48700-9N00B) was bad. This is a common problem on '09 Altima as well as 370Z. Dealer offered 10% discount and advised $600 total. I called Nissan customer care and escalated to regional office. This is a real safety issue because who knows where and when you can be stranded. Nissan has recalled this part on other models and discontinued this feature on subsequent models. This is a safety issue and something needs to be done!

Car will not start. The ikey light and the "red key" security light come on. The ikey opens the door locks, trunk. Holding the unlock key down resulted in the windows rolling down. Could not get the widows to go back up. Disconnecting the battery for 10 minutes, replacing the battery in the key fob, using either key did not work. Towed car to the dealer for diagnostics.

This morning was very cold. I warmed my car up, went to vote. When I left the poll, I get to my car and it won't start, says that there is no fob in the car. The red security light is flashing. So I put the fob in the "doghouse" that is supposed to work as a back up method.. nothing.. still won't start.. disconnected the battery, reconnected and tried again.. nothing. Did all my research to find many many page so complains about it.. it's the steering lock mechanism. Seems they did away with that feature in late 2010 models.. guess they know why.. so now I'm stuck with a $700 bill for an issue hundreds of people are having. As a matter of fact, my car was the second 09 of the day with the same exact issue. Coincidence?? I think not.

My car it would not start. There was absolutely no activation of the ignition system. After following all trouble shooting advice in the car's manual, I towed the car to dealer where they stated an open circuit in steering control unit is not telling the control unit that the steering wheel is unlocked and ready to start. The steering lock control unit (part# 487009N00B) needed to be replaced. This is all part of the vehicle anti-theft immobilizer system. The cost to replace this unit was $1,062.90. I feel this is a serious safety flaw in the 2009 Nissan Altima. 1. this was a fully functioning car (except for anti-theft glitch) that left me and my daughter stranded in a very remote area. 2. Nissan promotes how safe, reliable and economical their cars are, but the anti-theft system can disable the vehicle leaving driver stranded with only one option, which is, to be towed to a dealer because of ant-theft system glitches. 3. the car, being economical, should not require an over $1,000 repair because of an anti-theft device circuit malfunction. 4. there are several conditions that can occur that will result in the Nissan Altima becoming immobilized stranding drivers. I am stating only one. This is particularly dangerous especially to female drivers. 5. I feel that Nissan should come up with an override code or device that will allow a driver to escape from potentially dangerous situations that were created by Nissan's vehicle immobilizer system. Especially when the car is fully functional except for an anti-theft immobilizing circuit falsely telling that the vehicle is not ready to start. I believe this is a serious safety flaw in their vehicle security system.

Car will not start. The intelligent key warning light is on and preventing me from starting the car.

09 Nissan Altima just over 44K miles the steering wheel lock malfunctioned. No lights on dashboard, brake pedal very stiff, the vehicle will recognize that the key is inside and outside and is inserted at the location on the left side on driver and is able to lock and unlock but it will not start at all. Towed to dealer and as I am over my 36K warranty but not over the 3 year warranty I had to pay over $800 to fix for a vehicle that is not even over 3 years old. I will not buy another Nissan again.

Failure of car battery 18,730 miles I noted a strong smell of rotten eggs a few months ago and found that the positive post on the battery had considerable corrosion. I cleaned it off as best I could and hoped that would solve the problem. The smell of rotten eggs has continued and the corrosion returned and even more. It would appear that the positive post is no longer sealed into the battery. The battery is no longer a sealed maintenance free battery and thus is allowing sulfuric acid fumes to leak out around the post and corrode the terminal and all connecting cables.

Brake lights not lighting & push to start not working at times. Nissan said this is a known issue with the brake light switch & sub harness. After investigating the issue on the internet I found numerous reports of this problem. When the switch fails you are not aware of your brake lights not working.

I drove my 09 Altima to the mall parked it, an hour later I tried turning it on and it wouldn't start. No crank, and it wouldn't even go to acc. I tried jump starting it and even change out the battery but no luck.

My 2009 Nissan Altima would not start. Vehicle is equipped with factory intelligent key starting system, and the intelligent key warning light would blink on the dash.had vehicle towed to nearest Nissan dealer. A faulty steering lock control unit (part #48700-9N00B) needed to be replaced. This is becoming a common issue with 2008-2009 Nissan Altima's and other Nissan vehicles produced in those years. A recall should be started!

2009 Nissan Altima 2.5S was backed into in a parking lot, low speed collision, minor damage to rear bumper. A few days after this incident, when trying to start car with keyless ignition system, it took nearly 30 minutes to start. It is required that the brakes be depressed to start car, but when pushing on brakes, the brake lights do not turn on, and when ignition button is pushed it only turns on the accessories, which is the normal action expected if brake pedal was not being pressed. It is not clear if this is because of the collision or just highly coincidental. I believe that this is a problem with the brake switch. This is now an intermittent problem, but has made the car unreliable with the possibility to leave a driver stranded.

My 2009 Nissan Altima power windows that when you use the required buttons to raise the window or windows they raise themselves without the assistance of keeping your finger on the upside of the button. So they raise up automatically and if you have kids or dogs or someonewith their head, hands or fingers the window does not stop until it reaches the closed position. My dog was caught in one but I was fast enough to stop and lower the window. What if a child has any part of their body and one does not see them. These windows should not have the automatic up feature.

Intelligent key waning light would flash infrequently while driving and this warning warns of BCM failure and the end result is the vehicle will not start leaving the driver stranded at any place and time. Repairs have not been completed yet, but I was told that BCM replacement would solve the problem.

The 2009 Nissan Altima has an electrical discharge design flaw. The headlights turn off automatically after 5 minutes, apparently the battery rapidly drains even after the auto-headlight shutoff with the car turned off. I purchased a 2009 Nissan Altima 2500S December 7th, 2008, the car died January 23rd, 2009. I drove the car from home to work in the rain. The car was parked for around 10 hours, after returning to drive home, the car was dead - the keyless entry didn't work, using the mechanical key to enter the car, the start button didn't work. Aaa couldn't tow the car due to a height beam blocking the tow truck - the car couldn't be moved because the car was frozen in park due to the dead electrical system - the trunk couldn't be opened with the switch on the trunk or by the switch on the dash. Aaa jumped the battery and the car has run for 3 days now without any problems. The battery was so fully drained that the radio needed to be reprogrammed with the time and stations. This raises questions of how many safety systems relying on the battery will fail - for example the car can roll away if shutoff in neutral - if the battery discharges, is the shift gear then frozen in neutral? the rapid discharge of the battery with the car off is a design flaw which leaves the consumer stranded, potentially in a dangerous situation.
