I have owned a 2000 Toyota Echo since new and all maintenance has been done at the same Toyota dealership. It has been a reliable drive but it is over 20 years old.
There is one intermittent problem. When driving, it will stop and the engine will not restart. This behaviour is completely at random. It has happened when it was cold at a stop light. Today it happened just driving down the road. It occurs less than once a month. Leave the care to sit for 5 to 10 minutes and it will start. There are no other symptoms.
It has been taken to the dealership and they were unable to find anything wrong. And because it is intermittent, taking it out for a test drive has not been helpful.
My wife is the primary driver and the car stopping unexpectedly distresses her a great deal.
Any suggestion would be appreciated.
