every time I go over 85 mph my set light flashes and will not alow me to engage until I shut my car off for ten seconds.... this gets really annoying on the turnpike

 

I have an 02 and I frequently run to Houma La from Houston, and if I set mine pretty high, it kicks cruise off and my light flashes also. Same thing, shut the car off, get gas....good to go again. I dunno? Funny you brought that up.

 

Go slower

 

I just know that shouldn't do that and id like to get to the root of it. if anyone can give any insight to this nightmare please share lol

 

You are exceeding the design limits.

The cruise control has a specific speed range that it works in. On the low end, it is 25 mph. On the high end it is 89 mph.

From the 2002 Infiniti I35 service manual:

Automatic Speed Control Device (ASCD) allows a driver to keep vehicle at predetermined constant speed without depressing accelerator pedal. Driver can set vehicle speed in advance between approximately 40 km/h (25 MPH) and 144 km/h (89 MPH).

 

AS Dennis said... it has happened to me in the past when going over 90

 

This is new for me, Thanks for that info.

 

So your telling me that once I go over 89 mph I wont be able to set it again until I shut off my car? cuz that's whats happening, and its never done this b4...

 

Don't know
