My cruise control turns off by itself few seconds after I set it and the cruise control light in the dash starts to blink. I have to turn off the cruise control switch on and off to reset it but it does the same thing again. Does any one had a similar issue?

I was having the same problem for a little while on my 96 I30, but thankfully it went away (oddly) after a little time. I always blamed it on the car being a brat hahaha (partly my fault cause i spoiled her)...Maybe you should sit it out and wait for a little while, it may go away. If not i don't know bro sorry. Thought atleast my 2 cents would help a little.

I've had 2 A32 I30s now, no such problem on either of them. How often it happen? Once in awhile? Everytime?

might be a warning of an issue with the cruise system

It happens everytime I try to use it.

No issues with mine but do post back when you find it.

I imagine that the flashing is a "service me!" indicator of some sort & seem to remember that the owners manual tell of the flashing meaning that it's time for service.

Good luck....
