Unreliable starts

2005 BMW 6 Series 645Ci 2dr Coupe (4.4L 8cyl 6M)


At first I loved this car. I'm a low mileage driver and BMW tells me the car is meant to be driven a lot. If you don't drive it a lot this car is a life of hell.

The BMW dealer told me if I don't drive it at least one day a week for an hour the battery will die. He said there is too much draining the battery. It's not a week though.
Seven starts drains the battery.

I keep it on a trickle charge, but that apparently doesn't keep it from draining. After
the battery drains a couple dozen times, its time for a new battery which today cost over $500.
That's not acceptable but what is really unacceptable is having an $80,000 car that leaves me stranded and calling AAA once a week.

Best Features

The speed in 6th gear is amazing.

Worst Features

Let buyers know that if you are a low mileage driver this is not a car for you.

68,898 miles and bought brand new.. Never had a dead battery and this is only one of several I drive.. (it does sit for a week or more at a time)... I would have to bet that there is something else going on with yours..
