Let me add, I also noticed that anytime & everytime I use my turn signal ...the speed number display changes to a lower number momentarily ...regardless of using cruise control. This is wacky, and I guess I'll be looking to buy a replacement turn signal lever soon.
It took me a while to notice this added condition, because my eyes are fixed to my surroundings and mirrors as I normally change lanes.
Does the problem stem from the lever, column, or speedo display? ...voltage drop or wire grounding out?
...guess I'll just not change lanes till I can get it sorted...
