I've got a 2007 Murano that I have yet been able to diagnose the issue. When this first started I would try to turn on cruise and I would get a flashing cruise light on the dash but if I restarted the car it would typically go away. Then a few months ago I would set the cruise and it would turn off after a minute or so. A few weeks later I had the speedometer start bouncing and would got to 40 or 60 during driving. All of this with no related codes. I saw that changing the VSS was easy but that hasn't fixed it. I also have on TPS that has stopped sending pressure readings but I don't think that is related. Oh and occasionally the turn signal doesn't give the clicking sound but it has been returning so far.
