I have a 2008 Cayenne S.  Recently when starting I have turned the key and only had the engine turn over a couple of times, then stop.  If I turn the key off then try starting again, the engine fires up.


Is this a symptom of a failing battery?  I bought the car about 6 months ago so i don't know how old the battery is.  I have seen that the battery is under the drivers seat?


If this is a symptom of a failing battery, are there any recommendations on a replacement battery?

Go to the auto parts store to check your battery for free, open the hood and there is 2 battery post connections. 

I would not trust them to change the battery under the seat tho even if they could.

You can certainly have a local Autozone or Pep Boys check your battery or alternator condition for free but best to have a shop with the proper scan tools to check your Cayenne for any active and pending codes. A start stop like that could be any number of faults
