As the title states, I have been experiencing issues with my door locks lately. It first started with the rear driver side then expanded to the rear passenger side and now the front passenger side. The only side that has been unaffected is the front driver side, so far! The problem is that the doors will NOT fully lock when using the button on the door or the key fob. The problem is intermittent and doesn't seem to have a pattern. I should mention that it isn't uncommon for them to work and then not in the same day or even hour. My service manager seems to think that its the actuators? He greased the mechanisms, but it didn't solve the problem. I find it hard to believe that they would all go bad at once! I could accept this if it was one, but not three and I'm sure its a matter of time before the front driver side does it. Any ideas? It has to be something else!

 

I haven't heard of this problem.

Where you are saying 'NOT fully lock', I assume you mean that some doors fully lock and some simply stay unlocked.

If that is the case (and I am sure that is what you are saying), and you have a situation where doors that don't lock one day may lock the next, this means the mechanisms inside the doors work when properly triggered.

If this were with one door, the problem could possibly be inside the door. But with three doors involved, this almost has to be an electronic problem in the central door locking system, and should certainly have nothing to do with anything being wrong inside the doors.

This is something that will require a good automotive electronic diagnostic service man, and is not something we can fix on our own (unless we are astute automotive electricial diagnosticians).

 

Thanks for the reply light! I'm in complete agreement with you. When my service manager said that he wanted to replace the rear door actuators (driver and passenger side), I told him to hold off as he wanted $195 per door. Shortly thereafter my appointment, the front passenger door lock started acting up! To clarify, your assumption was correct, the door lock will not fully switch to the locking position, the locking mechanism may move slightly, but not enough to switch from unlock to lock or vice versa. Then, it will work again, maybe later that day or the next, before failing again!

 

You no longer have warranty coverage?

 

I had a similiar issue with my 2009 when I first got it. There was a loose connection in the plug behind the speedo, that goes to the Body Control Module. Apparently a pin had worked itself loose out of the plastic housing of the connector.

 

I didn't purchase an extended warranty so I am not sure?? How long would something like this be covered?

 

This problem would come under the 36 months, 36,000 miles (whichever comes first) warranty.

 

Not sure if it could be related, but when I use my key fob to lock my doors, the chirp that you normally hear doesn't always work. I don't shut it off either?

 

doesnt sound right 4 all 4 door actuators to go out. look at "09Maxima_Sam's " fix

 

Still haven't gotten a chance to get my car in to the dealership, but I am now noticing that my horn isn't working when I attempt to hit in on the steering wheel?!?! Do you guys think this has something to do with the main electronics? Thanks!
