My car was bought last August from a main Toyota dealer, 3 years old and in showroom condition. Occasionally when I'd turn the key nothing happened, dead.... I'd try a few times and it would start on perhaps the 3rd or 4th effort.
This was very intermittent and I mentioned it to the particular salesman one day who said just to call in with it. Another few months passed.
One mornng a few weeks ago when it happened again I decided just to drive over to the car dealership. No appointment but was given absolute courtesy, salesman sat and yarned with me, got me a coffee, called the service department and a service guy (SG) came around to chat with me.
Anything that came to mind to him he felt would occur regularly so he took my car over to the service department there and then, have another coffee, it'll take about 20 minutes.
SG comes back having checked all and says car is perfect. SG says.... May I ask Coolgran, are you sure to always put your foot/clutch to the floor when you turn the key. Or do you have an extra set of floor mats in your car.
Hmmm says me .... I guess I put my foot to the floor, I just do it automatically, don't take note, and I've never had this problem before. And No, no extra or different car mats.
SG says.... can I tell you that Toyota have a safety system and if the clutch is the slightest touch off the floor when turning the key, it will not start. Just in case a child may try to mess with the pedals.
You may feel that your foot is to the floor, try making sure that it is to the floor and see what happens. Don't hesitate to come back if necessary.
It has never happened since.
