I have an 01 IS200 with 98K miles on clock.
This problem only occurs in cold damp weather during winter.
After starting the car and driving for ten/fifteen minutes dash warning lights all flash on and off once. Immediately afterwards headlights go out and needles on dials all go to zero. Otherwise car contines to drive normally.When I pull in and turn engine off/on the problem is resolved and does not recur again on journey.
Car has been checked by main dealer and independent mechanics who can not identify problem.
Any suggestions?
