I have a 2010 g37x coupe, just realized when i try to set cruise it doesn't work. The cruise light is on and shows in the dash but when I try to set I just end up losing speed.
Have checked google and found some things saying to turn wipers off while setting and/or pull the break pedal up with your foot before hand. Neither work.
I tried it once more today and something happened I've never seen before, turned car on, turned cruise on, and pulled out. Heard a beep and there was something that looked like an arrow on the dash screen and disappeared when I accelerated over 40km/h. I'm guessing it's some time of sensor that tells you to accelerate past a certain speed before setting cruise speed?
Anyway, anyone else have this issue or might have an idea to help?
Thx

 

I'm having the same issue with my cruise control... 2008 G37s. w/o Nav.
Have you made any headway on figuring out the problem
