550i Slow crank?

So I have a 2008 550i sport and it cranks very slowly and then once it fires it starts very quickly. Almost sounds like a weak starter. Is this normal? Anyone else experiencing this?

Re: 550i Slow crank?

That's what I thought. I looked at the service records and the battery was changed once already. The car only has 45k on the odometer.

I agree with Batmbl could b your battery , also a sign of a week alternator. Be ready for some screwy malfunction errors .... Due to alternator starting to go bad, not fully charging the battery,,

Is that normal at this mileage? My 1995 540i with 135k needed an alternator at that age, but this car is babied. Is it possible to get a bad factory one.
