Well My lane detection system is not working properly, If i get close to a line(not on it or going over it) it will blink and make noise. It is supposed to do this when I go over it or cross it. and when it rains It goes off like crazy, I had to turn it off. I paid extra money for this option and now it is just turned off, I took it to the service dept. and was told there was nothing abnormal. Everything I took my car in for they told me nothing is wrong and that it is all normal, after creating a case with nissan and took it back they fixed three out of 12 of the items but this is one they did not, very upsetting.
