Question about cruise control on 370z

speedracer007 · 09-14-2016, 07:18 AM

So my cruise control has become intermittent now again. 1 1/2 years ago I was having the problem of the cruise sometimes engaging / disengaging and I took it into the dealership (still under warranty).

When I got it back, was told they had to replace some switch.

Well it has started up again and now I am not under warranty.

Same symptoms as before:

1) Green light comes on, but cruise does not set when button pushed.
2) Lift up the brake pedal with foot and I can engage cruise.
3) If I hit a bump or rough patch of road, cruise disengages.

So looking at the pictures that mults posted above, it seems like I need to make an adjustment to the UPPER SWITCH (I have an Automatic). I assume that I need to adjust nut 3 to move the switch such that it is a little bit lower in order to touch the plate on the brake pedal. It would seem that I would want to make slight adjustments, because you still want the cruise to disengage when the brake pedal is pushed.

I looked into this when I first had the problem, but since it was under warranty took it into the dealership. I asked the Tech when I picked up the car if they had to make an adjustment to the switch, but he said "Oh no, we had to replace it". I am hoping that was just dealership mentality of lets replace a part with a new part instead of just making an adjustment to a perfectly good part.
