I have a '99 Maxima...
What does it mean when your security light is solid while driving?
It happend to me a couple times, but i shut it off a couple times and it went back to normal. I was just curious what it meant.

 

This also happened to me once....I thought i remember reading something about it but I have a 99 and after doing some work....cleaning the starter or something it did that for the first time running the car, once I stopped and shut it off then restarted it never happened again.
