I have the exact same thing happen when the ABS light intermittantly comes on. I have checked my fluid and it is topped off. Yes I have an intermittant ABS light and I understand that may indicate that I have a bad HUB. The point I trying to make is the cruise only fails when the ABS indicator is on. There is never a low brake fluid light. Could the ABS be trying to tell me there is a problem with the fluid level sensor? Just asking.
