detected speed limit very wrong

[SteveDC]

Anyone see this problem before and what would it mean if you had active cruise control set to follow the limit? BTW, the speed limit in this neighborhood is 15 mph, and the area before it was 35. The Porsche continued to show 65mph as the limit past multiple signs posting speeds of 35, 40 and 15. Normally it detects correctly. Glad I didn't have the cruise set today!

I had the same thing in my 21 MY 4S. The indicated posted limit would freeze after several minutes of driving. My dealer me that I had a defective CPU and replaced it.
