Focus start-up

From time to time my 2010 Ford Focus refuses to start. When it does nothing happens, the engine doesn?t turn over, none of the accessory lights turn on, the radio doesn?t turn on, but I could go back to the car a few hours later and it could go again. The RACV man said it could be interference from other cars or phone towers. I have taken it back to the dealer several times, but it has not been fixed because they cannot replicate the problem. What do you think is causing the problem?

It could be interference from other sources, such as phone towers, but normally you would find that it happens at the same place every time, and when it does you should be able to see a phone tower or something like that nearby. If it happens randomly I would look for some other cause. The immobilizer is a good place to start, it’s possible that it’s not communicating with the car’s computer, but it’s a very difficult problem for a dealer to diagnose when the problem can’t be replicated. Perhaps also consult a locksmith.
