2004 Toyota Sienna 6 cyl Two Wheel Drive Automatic 102000 miles
When driving on cruise control, the dash board lights all come on, the speedometer flips between 30 and 70 mph, the radio cuts off and the only way to " reset" it is to put it in neutral for a short period of time (10-20 sec). This happens once in a while and when on the highway. It has been into the dealer 4 times with no luck and $3000 in costs. Any ideas.
