Automatic 2004 Outback 2.5i Safety. Cruise control was set to 110kph and we were pulling up a long incline. The speed had dropped back to around 100kph. Without warning the cruise control dropped out. Disturbing.
Pulled to the side and was engine idling normally - then drove off normally. Used CC all the way home for the next 150km no problem.
About 10 minutes after the event I glanced at the display (which was set to outside temperature at the time). It was flashing and showing something like [20 0] for just a few seconds - like an error message.
At service a few days later the local dealer could find no problems or stored errors - but apparently these are cleared if not repeated with
80 km or a certain amount of driving time occurs without a repeat error.
Any thoughts.
