Hi Guys.
07 Ford S-Max 50k mileage.

Car is driven every day exactly same way on exactly same distance.
Problem is that every few weeks battery goes completely flat ! Trying to start the car in the morning and NOTHING ! Battery is completely flat. When starting it with cables using another car it starts straight away.
I've checked the battery and alternator with voltage meter and everything is fine. It looks like something is draining power but couldn't find anything. No lights left on etc. It does like that every few weeks !

Another thing is that brake light bulb (always same one) is getting burnt every few months. Can this be related ?

According to service history, papers and invoices that came with the car, this car has the battery changed 3 times already !!!

Any ideas ???
