This is the second time it has happened, and the Lexus Service department was unable to figure out the problem. Driving back to DC from Baltimore I came off 295 onto New York Ave. and applied about medium braking in order to stop at the first red light. Upon stopping, there was a deep clunking noise and the engine cut off. All the lights (chekc engine, oil, battery, etc.) within the driver's console (speedometer, RPM,etc) lit up. I then had to put the car into park and start the engine again. The console lit up the same way it does when you turn the key into the third position, right before starting the engine. This is the second time this has happened this month, and I will be going back to the lexus dealership next week, but has anyone else encountered this problem? Any assumptions to what may be the problem? Any help would be much appreciated. Thanx in advance.
